Roy Diblik’s Grand Geneva Resort Garden in Mid-June

0162
Last July, I visited Grand Geneva Resort and Spa, not to play a round of golf, but to check in on the Roy Diblik designed garden that they have out in front of the main building – you can read more about that <here>.   This past week, I took another look at the garden, this time in Mid-June.  While there where many colors showing in July, shades of purple dominated the palette in Mid-June.  In the photo above, the globular flowers of Giant Purple Allium (a Dutch Bulb) complement the various shades of Blue Salvia.

0163

In the foreground the monochromatic color scheme is set of by bright green masses of Sesleria autumnalis, Autumn Moor Grass. 

In the photo below the dark green strappy leaves of Allium ‘Summer Beauty’ weave in and out of the small gray-green leaves of Catmint (Calamentha nepeta var. nepeta.)  In a few weeks both of these will be in bloom with balls of pink flowers and a mist of white flowers respectively.

The Purple Coneflower in the center foreground waits its turn to put on its show of flowers, while the Yellow Baptisia (Baptisia sphaerocarpa) is just finishing up and starting to set its ornamental bean-like seed pods.

0169

Bowman’s Root (Gillenia trofoliata, now known as Porteranthus trifoliatus) is native to the Eastern half of the United States (including Illinois) and parts of Ontario, Canada.  Tolerant of Shade (naturally found growing in moist woods) is can take full sun as well.  American Indians used the plant extensively in their herbal medicines, which you can read more about at the University of Michigan’s website <here.>  The plant can reach heights of 2 to 3 feet or more, with an equal spread.  The Plant is covered with 1″ five petaled, star shaped flowers, the fall color is an excellent orange/red color.

Not too much going on in this little bed in Mid- June:

Lots of green in this bed in Mid-June

But the same bed a few weeks later, in Early July of last year, is a real riot of color – the garden is designed to change throughout the growing season with layers of color emerging as others fade.

A few weeks later, its comes to life with burst of color

And that is why I enjoy visiting gardens designed by Roy at different times of the year – it’s a great lesson in how to arrange plants so even when they are not in flower, the planting is still an interesting mix of textures and plant forms … at some point in the season though, each part of the garden, or plant combination, has its moment in the sun -just like fireworks on the fourth of July – each successive display is unique and awesome in its own way.  And just when you think you’ve seen the best, a new display explodes before you with another amazing mix of colors and forms.

A Visit to Roy Diblik’s Northwind Perennial Farm in Mid-June

0143

One of the many vignettes at Northwind: a rustic shed with chives and geraniums in flower.

As I drove up to Northwind Perennial Farm, in Burlington, Wisconsin, on Saturday, June 14th, I was met with cars parked all along the street, in front of the nursery.  At about the same time, I saw a turn off into a grassy area of the nursery for overflow parking.  The nursery was holding an antiques fair that Friday and Saturday – I was more interested in seeing the gardens in early June (I visited last year in late July, which you can read about <Here>).  For a little background on Roy and his business partners Steve Coster and Colleen Garrigan there is a good article by Beth Botts which you can find <here>.

0127

The display gardens help the visitor see, literally, what the plants will look like when they are mature specimens – the garden is always changing throughout the season.

As I pulled into the impromptu  parking area, I saw Roy walking by himself taking pictures of the all of the cars.  As soon as I found a parking space, I grabbed a copy of Roy’s book, “The Know Maintenance Perennial Garden,” from my back seat a walked over to Roy.  I introduced myself, mentioned that we have met in the past, and would he mind signing my copy of his book.  He smiled, and said “Sure, but I don’t have a pen,” I quickly raised my other hand holding a pen and smiled.   We talked for about ten minutes – a very pleasant chat about nothing in particular, but it felt like I was talking with an old friend about that I have known for years.

0049

Geranium ‘Orion’ in the foreground with pink chives and blue salvia behind.

With all of the nearby buzz of the antique sale going on, here I was chatting Roy about his new book, the plants he grows, and life in general – it made the 110 mile journey to his nursery all that more worthwhile.

0044

At the end of our chat, he did take my book and signed it “Roy” along with the note to “Always share the joy of gardening!! Have fun!!”  It was the beginning of a very nice visit to Northwind Perennial Farm.

0047

If the plants in the display garden look familiar, then you may also have visited the Lurie Garden in Chicago’s Millennium Park – the garden was designed by Dutch nurseryman Piet Oudolf but the plants were grown by Roy, and many of Piet’s plant choices were inspired by Roy and his love of prairies.  Roy has also designed many gardens on his own, including ones at the Art Institute of Chicago (on the northeast and northwest corners), the Shedd Aquarium (that I still need to visit) and one I did visit last weekend at The Grand Geneva Resort, in Lake Geneva, Wisconsin, and many, many more – all based on his “Know Maintenance” approach to garden design, a process of designing communities of plants that work well together, and look good, with a minimum of necessary maintenance – an approach detailed in his latest book: “The Know Maintenance Perennial Garden.”

0068

The sound of water is always a welcome sound in the garden – here, a waterfall is artfully placed in the landscape at Northwind


0142

The blue flowers if Skullcap, Scutellaria incana – a southern Midwest native, are impressive


0141

Skullcap prefers some protection from the afternoon sun and naturally occurs under trees along waterways

The  retail yard at Northwind is divided loosely into plants that prefer sun and plants that tolerate or do better in shade, as well as an area with a variety of grasses. 

Some of the plants are pulled together as suggestions of good plant combinations and to show how they would look in a garden setting:

0140

‘Husker Red’ Penstemon, ‘Walkers Low’ Catmint, and ‘Blue Star’ Amsonia

The sun loving plants in the sales area:

0134

This past Sunday The display gardens are helpful in that they show how plants don’t have to be massed in large groupings of one species, next to another large mass of another species, the image below shows a nice alternative, the planting below also demonstrates that leaf texture is as important as flower color – maybe more so. Lesson learned.

0124

Good use of color, on the other hand, is also demonstrated in the gardens at Northwind:

0126

A monochromatic combination of blue Salvia ‘Wesuwe”, along with a hardy geranium and a Purple Allium grown from a bulb.

One plant that caught my eye, that had no showy flowers, was Palm Sedge (Carex muskingumensis), a Midwestern  woodland native:

0123

Palm Sedge, the bright green fine textured foliage works well with other plants – in both sun or shade (with good moisture)

It was growing in an open, sunny area, and was as big as a bushel basket. Very dynamic, and showy.  I need to divide the ones I have growing  my garden, get them out in the sun and also give them more room to develop into specimen plants.

0122

This Palm Sedge was about two feet tall!

Some Plants in Bloom:

The salvias were in bloom, the Lurie Garden is well know for its June blooming “river” of salvia running down its center.

0120

‘Blue Hill’ Salvia, there is also a white version, called ‘Snow Hill’

0091

Salvia ‘Wesuwe’

0118

Kalameris incisa ‘Blue Star’

0085

White ‘Alba’ Dwarf Chives

0095

‘Husker Red’ Penstemon

0063

Yellow Indigo, Baptisia spaerocarpa

0054

Yellow Indigo, three feet tall and wide. Bold!

In one of the shady gardens, I was blown away by the  hardy geranium ‘Magnificum,’ aptly named, growing behind a low stone wall constructed by Steve Coster, Roy’s business partner.

0132

The flowers of Geranium ‘Magnificum’ glow in the shade

0133

The color of Geranium ‘Magnificum’ is electric, to day the least – sadly, I didn’t notice any for sale the day I was there.

While chatting with Roy earlier in the production area (overflow parking) he recommended Monarda bradburiana, a native horsemint.  Last year, while visiting the nursery in July, I saw Monarda ‘Coral Reef’ in flower and bought a plant to try in my garden – the coral pink flowers were pretty incredible.  The Bradbury Monarda is a native of Missouri – however, Roy first saw the plant growing in Europe, liked its short habit, at about 20 inches, and its early bloom, about a month earlier than other monardas and decided to grow it in his nursery.  Monardas are great at attracting butterflies and this one would make a great combination planted with Pale Purple Coneflower (Echinacea pallida) – another butterfly magnet, whose bright shades of pink would complement the more muted tones of the Bradbury Mondara – both like full sun.

0100

Bradbury Monarda

The yarrows (Achillea) looked tempting, I especially liked that they had great gray foliage.  The yarrows have a long bloom time, and the flowers dry well for winter arangements. The five foot tall ‘Gold Plate’ Yarrow could add a lot of drama to a garden.

0148

‘Coronation Gold’ Achillea (Yarrow) 36 inches tall, golden flowers

‘Coronation Gold’ Achillea – finely cut silver foliage

‘Moonshine’ Achillea – 24 inches tall, yellow flowers

0152

‘Moonshine’ Achillea – Ferny, silver foliage

0156

Achillea filipendulina ‘Gold Plate’ – 5 feet tall!!! Yellow flowers

Some of the plants that I bought:

Columbine Meadow Rue, Thalictrum aquilegifolium

Columbine Meadow Rue is native to woodlands across Ontario, Canada and New York State.  The pink stamens are the showy part of the flower, while the blue-green divided leaves are reminiscent of native columbine.  This plant will tolerate full sun,  but as an understory plant, it would make a nice addition to the shade garden with its tall (36 inches), airy habit and late spring blooms.

0093

Meadow Rue

St. Bernard’s Lily, Anthericum ramosum

This Eurasian native caught my eye due to its interesting growth habit of 20 inch long, gray-green narrow leaves forming a clump, with 30 inch long wiry stems topped by white star-shaped flowers.  It apparently likes full to part sun with average, well drained soil.

0115

St. Bernard’s Lily

Prairie Golden Aster, Chrysopsis camporum

Now known as Heterotheca camporum, Prairie Golden Aster is a Midwestern Native that I first saw blooming at Taltree Arboretum, in Valparaiso, Indiana.  Often found growing in sandy waste ground, it will be interesting to see how this  plant performs in a garden situation.  Full sun and well drained soil is what this plant seems to thrive on. Plants can grow to three feet tall and two feet in width.  The one inch, daisy-like flowers are noted to bloom for most of the summer.

 The Antiques Fair

While I didn’t choose this weekend to visit Northwind because of the antiques fair going on, it was a somewhat interesting diversion.  I was at least hoping for a garden themed sale, and it was, to a point, but most of the stuff for sale was better suited to the sun porch than the actual garden. I did, of course, have a good time poking around the nursery in search of new ideas and plants, it was just a really nice bonus to bend Roy’s ear for a few minutes before entering the melee.

0037

0069

Paint it white or Martha Stewart green and it will sell – well that seemed to be an apparent thought among vendors anyhow

0074

I did find these garlands made of sheets of phone book paper rather interesting in a grade school Hawaiian lei made of Kleenex kind of way.

0071

I envisioned vines growing all over this wire chair

0080

In the barn were some silverware wind chimes – a massive chandelier would be cool – hang it in the woods as surprise .. hmmm, upcoming project?

Early May Blooms, Mixing Natives with Other Plants in the Shady Perennial Garden

9259In early spring many of the Midwestern woodland wildflowers bloom before the trees (mostly oaks) fully leaf out and create a shady canopy.  There are also a few garden perennials from other parts of the world that bring color in to the early May garden.  Let’s take a look a few that are at their peak of bloom right now. 

In the picture above, common violets intermingle with Jacob’s Ladder (Polemonium reptans).  Violets come in many shade of blue and purple, as well as yellow and bicolor blue and white.  The violets above were propagated from a naturally occurring population that had reddish purple coloration (difficult to capture in an image) that complements many other early bloomers, including Ruby Epimedium (Epimedium x rubrum), seen below.

9260

9205

9254

The leaves emerge a bright chartreuse green on the Ruby Epimedium – planted where the morning sun highlights this stunning color.  The leaves turn a more standard green as they mature.  Epimedium sulfureum, a similar species, flowers  in yellow but does not seem to be as robust.  At a foot or so tall and wide, epimedium works well in part shade in groupings of five to nine (or more)  interplanted with other perennials. 

Trilliums, such at the White Trillium (T. grandiflorum) seen below, are often collected from the wild and sold in garden centers, there are, however, some ethical nurseries that propagate their plants from seed or divisions – easy to do, and should be purchased from those sources.  Timing is critical when collecting the seed, generally eight weeks past flowering, since the pods will eventually shatter and the seeds will drop to the ground – as long as the seeds are turning brown, they can be collected and planted in seed flats to expand a population of plants.

9240

White Trillium, aka. Large Flowered Trillium – a easy to grow shade plant

9242

Toad Trillium, T. sessile can have dark purple/black leaves as they emerge in the spring.

Trillium plants will fade after flowering and go dormant until reemerging the following spring, therefore it is best to plant them where the soil will not be disturbed – such as near the base of trees or large rocks.  Other native woodland plants such as Hepatica, seen below, actually send out their new leaves for the season right after flowering, and look great all summer, and stay green through the winter season, only fading the following spring.  Flowers, which range in color from pink, to white, to purpley blue, sometimes emerge as snow is still on the ground in late April.

9212

Hepatica acutiloba now known as Anemone acutiloba, showing seed clusters

Rue Anemone, like hepatica, is a member of the short flowing buttercup family.  The flowers are pure white to slightly pink, with blue green leaves that remain throughout the summer if the soil does not dry out for an extended period.  Rue Anemone looks great tucked into nooks and crannies throughout the shade garden.  Leaves turn yellow in the fall months.

9246

9202

Rue Anemone, Anemone thalictroides aka, Thalictrum thalictroides.

Lenten Rose (Helleborus sp.) is native to Europe and blooms along with the native woodland flowers.  The large, coarse flowers can be an interesting complement to the other finer textured flowers in the shade garden.  These easy to grow perennials can be divided after flowering, by cutting apart divisions with a bread knife, to create more plants.

9199

The flowers of Lenten Rose, ‘Ivory Queen’ last for several weeks

The low groundcover Sweet Woodruff (Galium odoratum) is widely found growing in moist woods throughout Europe and Asia, it also mixes well with our Midwestern natives as seen below with Woodland Ginger (Asarum canadense). The leaves of both the Woodland Ginger and the Sweetwoodruff wil stay green all summer if the soil is kept moist during dry spells.

9415

Wood Shield Fern (Dryopteris marginalis) and Christmas Fern (Polystichum achrosticoides) are two easy to grow evergreen ferns native to the Midwestern woods.  Wood Shield Fern’s, upright vase shaped growth, can reach two feet tall, while the Christmas Fern is more low spreading.  Below both are seen mixing well with Woodland Ginger (Asarum canadense), Wild Ramp (Allium tricoccum), and Woodland Geranium (Geranium maculatum) with its pink flowers just coming into bloom in Mid-May.

9413

Christmas fern at lower left and Wood Shield Fern at upper right

Jacob’s Ladder (Polemonium reptans) is a neat low mounded woodland plant covered in sky blue flowers for a week, or so, in May.  The rest of the summer, the pinnate foliage looks great and work well, planted along the edge of the shade garden as a nice transition to lawn or other pathway materials.  The Jacob’s ladder often found in garden centers is a taller European variety, with variegated foliage – inferior in appearance to our Midwestern plants.

9490

Polemonium reptans halfway through its bloom cycle

 Blue Wood Phlox can be found blooming at the same time as Jacob’s Ladder, and slightly after Jacob’s Ladder is finished blooming.  In May wiry flower stems shoot up a foot above the low evergreen foliage and put on a bright blue display that works well with other more sun tolerant Dutch bulbs such as Grape Hyacinth (Muscari sp.) and Tulips.  9453A mix of blues and whites in a rock garden I constructed at my home, gets plenty of sun in the spring, but is somewhat shaded by the overhanging Silver Maple in the summer:

9455

9462In one part of the rock garden, the shade tolerant Sedum ternatum, native to Midwestern woods and limestone bluffs is just starting to put out its white, star shaped flowers.  The sedum stays evergreen the year around and works well as a groundcover in the shade garden.

9458

Illinois Stonecrop, can be found on limestone bluffs as well as floodplains (Swink & Wilhelm)

Most sedums, this one included, can be propagated by pinching off a short stem and pushing the base of the stem into the ground where more plants are desired.  Occasional watering of the cuttings will promote quicker rooting.

9460

Sedum ternatum with Blue Wood Phlox in the shade garden

Virginia Bluebells (Mertensia virginica) is such a ubiquitous old fashioned perennial, that many gardeners are unaware that it also is a American woodland native – mostly found in flood plains, but very adaptable to well drained garden soils.  The charming bell-shaped blue flowers only last a week, then the plants begin to wane, turn yellow, and go dormant for the summer, it is therefore a good idea to note where these plants occur, so that the plants are not inadvertently disturbed while gardening in the summer months.  Interplanting Virginia Bluebells with others perennials that will help mask the fading foliage is something to consider as well.9438Virginia Bluebells can form large colonies by dropping its seeds in bare soil surrounding the mother plant, these volunteers are easily removed if desired.  The roots are fleshy and can be divided after the plants are finished blooming to create more plants.  Virginia Bluebells will do well in most decent garden soils.

9434

A mass of Virginia Bluebells overtake the low evergreens when in bloom, only to quickly retreat with equal vigor

Another early blooming European native is the old fashioned Money Plant (Lunaria annua.)  Grown for the silver dollar sized papery seed pods (silicles) that are used in dried arrangements.  This plant will reseed around the mother plant, and in some soil types this may be a nuisance.  In my experience, the mother plants have survived many winters (unlike what the name implies) to rebloom in the spring and provided more dried arrangement material the following fall.

9428

German Money Plant in the back of the herb garden – growing in very dry crumby soil

9424

The four petals indicate that the Money Plant in a member of the cabbage family (Brassicaceae)

For a punch of bright orange in May, Trollius europaeus, or Globeflower, cannot be beat.  The plant, hailing from Europe,  prefers a bit of shade and consistently moist soil but otherwise is a rather carefree perennial.  It blooms at the same time as some of the Giant Purple Alliums  and Chives and the purplely pinks allium blooms could make for an interesting combination with the bright orange blooms of the Trollius.

9477

9479Lastly, we get back to some Midwestern natives for the shade.  Many sedges do well in dry shade, Penn Sedge (Carex Pensylvanica) being one of them.  This sedge is one of the “sod” formers, as opposed to forming neat tufted “clumps.”  Use this growth habit to your advantage by interplanting such shade plants as the trilliums, noted earlier, violets, whose electric blue flowers play well with the bright green foliage of the Penn Sedge.

9264

The course foliage of Ramps (middle right) works well with the grasslike foliage of Penn Sedge

The flowers of the Penn Sedge are a bit underwhelming, but the yellow anthers can sometimes be considered a bit showy in mass plantings.

9404

Penn Sedge spikelet – not showing yellow anthers in this photo – few seeds, seen in front of lower finger, are produced and are difficult to collect, as they drop immediately when ripe

All Violets (Viola palmata shown below) look great interplanted with other woodland plants, especially Penn Sedge.

9440

Palm Violet

  As do specimen plants such as Jack-in-the-Pulpit (Arisaema triphyllum).  While the plant itself goes dormant after bloom, a showy red seed mass forms to catch the viewers attention in late summer, very cool:

9371 Or Sessile Bellwort (Uvularia sessilfolia) whose foliage looks good througout the summer.  The dainty pendulous yellow flowers are curious, if not overly showy.

9257

9250

 These are just some of the interesting plants that come into flower early and can be combined with each other and with later flowering plants to great effect.
