September Highlights

Rock Pink

Rock Pink (Talinum calycinum) has been in bloom for weeks and it just got better and better, as long as the warm weather lasted. I love the bright magenta of the flowers against the natural greys of the rocks and stone mulch. I hope it proves to be hardy, here in western Quebec, but even as an annual it is worth growing for mid to late summer colour in the rock garden. Small bees love the flowers.

Ironweed

A useful contrast to all the tall yellow daisies, the bright saturated purple of ironweed (Vernonia sp.) glows in the autumn sunshine. This plant is tall and rugged.

Ironweed and Switch Grass.

Tall Sunflower

Of the many tall yellow daisies for late summer and early autumn, my favourite is Tall Sunflower (Helianthus giganteus). It can be very tall – to 3 metres. That’s a plus. If you are going to do tall, do it! Even small gardens have lots of room in the vertical direction. Tall Sunflowers flowers are a lovely clear yellow and the purple stems are a nice contrast. On warm afternoons the plants hum from the volume of pollinators. After the flowers fade, the seeds are relished by goldfinches.

Heart-leaved Aster

Now, I warn customers that pretty Heart-leaved Aster (Symphyotrichum cordifolium) is a pushy native that spreads, but let’s face it: most gardens have spots where a tough, pushy plant is just the thing. We have an ancient clump of common lilacs, as do most old farmyards. The lilacs are fragrant and lovely and visited by Canadian Swallowtail Butterflies, for about a week in the spring, and then, for the rest of the summer, they are a big, boring green lump with no fall colour. Heart-leaved Asters are willing to grow in the dry root-filled conditions under the lilacs and bloom in a beautiful pale blue ruff at their feet. Like other asters, they are important for late-season pollinators.

Closed Gentian

Daisy-form flowers dominate late-season wildflower gardens. Native plants with distinctive and unusual flower shapes are always interesting and even more welcome when they bloom in the fall. This is a white-flowered garden selection of the native Closed Gentian (Gentiana clausa).

Small-flowered Sundrops

It is difficult to convey in a photo the great charm of Small-flowered Sundrops (Oenothera perennis). I was heartened recently when some discerning customers at the nursery made a bee-line to it.

Compared to the enormous luminous flowers of Ozark Sundrops (Oenothera macrocarpa), or the great flower masses of citrine yellow of Common Sundrops (Oenothera fruticosa), the flowers of Small-flowered Sundrops are indeed small. However, in a wildflower setting, where its companions might be Hairy Beardtongue or Long-leaved Bluets, the Pointillism-like effect of small dots of brilliant yellow is exactly right.

Beaux Arbres’s stock of Small-flowered Sundrops is from locally-sourced seeds. The plant makes small mound as wide as it tall, studded with brilliant yellow flowers in early summer. The fall foliage is a vivid red. The plant is more tolerant of light shade than you might expect from an Oenothera, sometimes found in open glades in woods.

Shining Rose

Another wild rose we are propagating at Beaux Arbres is Shining Rose (Rosa nitida), also known as Maritime Rose. I collected the seed for this species in Nova Scotia. I understand it occurs in Quebec along the Gulf of St. Lawrence shore but it does not occur naturally in the Ottawa valley.

I particularly like this rose for gardens because of its relatively low stature and its fine foliage texture. Its leaflets are smaller and shinier than those of other North American wild rose species, Shining Rose has fabulous fall foliage colour — flaming reds and oranges — and small red hips. Its suckers in loose sandy soil, as do most wild roses, but it is constrained by tighter clayey soils. Topping out at three feet or less, Shining Rose is the ideal wild rose for smaller gardens.

Thanks to all our FWG customers!

Another successful sale at the Fletcher Wildlife Garden! Thanks to all the FWG volunteers who put on this wonderful event and thanks to all our customers, some new, some familiar faces.

If you were not able to get to the FWG on Saturday morning, Beaux Arbres has an even greater selection of native plants available at the nursery. Please phone (819-647-2404) or message, to confirm we are open. We are open any time we are there.

Our next events are not until August: the Pontiac Garden and Gifts Tour on the 4th and 5th and our own Open Garden Day on Sunday, the 26th.

I now have time to do the long neglected task of actual GARDENING at Beaux Arbres, although propagation still continues. I will post about new and interesting species throughout the summer.

Michael is planning some basketry workshops at the farm this summer.

 

New Species for the Fletcher Wildlife Garden Sale, June 2

I am almost too busy getting the plants ready for the sale to blog about them but there are a few new species that are too interesting to ignore.IMG_0942

Seeded earlier this year and already big enough to plant now, the lovely biennial Swamp Thistle (Cirsium muticum). I know, Swamp and Thistle. Don’t let your experience with weedy non-native thistles, neither the stately but dangerous Bull Thistle nor the absolutely appalling Russian Thistle, put you off this great native for damp spots. It is so unlikely to seed into gardens that I suggest you collect some seeds in the fall to ensure you don’t lose it. I received my seeds as a generous gift from Lis Allison, whose Pine Ridge Studio, near Carp, is a great source for locally grown native ferns. Native thistles are great nectar sources for butterflies and the nutritious seeds feed many birds.

Also new this year: Dwarf Arctic Iris (Iris setosa var. arctica), a miniature wild iris and seriously cute. We have some in bud. Seriously cute. Shop early.

We are bringing a few pots of Rock Whitlow-grass (Draba arabisans). Perhaps not the most exciting of Drabas — the really tiny, exciting ones are all denizens of either the high Arctic or Alpine peaks and dislike hot weather — but we just this past Sunday saw this species used very effectively in the Natives area of the Alpine Garden of the Montreal Botanical Garden (featured image). This Draba species is an easy  plant for rock gardens, small enough for troughs.

And speaking of rock gardens, yes, we will have lots of Common Bluets, still happily blooming.IMG_0948

We will not be bringing many shrubs to the sale this year — three species of roses, some Shrubby Cinquefoil, a few others. Plan to come out to the nursery for more shrubs.

The Fletcher Sale is the only time we bring the mid to late summer meadow flowers into Ottawa. They won’t be in bloom now, of course, but take the opportunity to add some great heat-loving natives, for flowers throughout the summer. Many of the prairie and meadow flowers are important nectar and pollen food sources for diverse pollinators: Boneset, Great Blue Lobelia, Cardinal Flower, Swamp Milkweed, diverse yellow daisies and many others. New this year: Rattlesnake Master and Tall Coreopsis.

 

New Species for sale Sunday

We have always tried to have some genuinely rare and/or unusual plants for the Rare and Unusual Plant Sale . This year we have some new and very special species.

We are keeping a close eye on our pots of seed-grown Eastern Shooting Star (Dodecatheon meadia). This species is not locally native; it occurs in Canada in Manitoba, with a wider distribution in the U.S.A. Beautiful and distinctive, Shooting Star is on the logo of the North American Rock Garden Society. Shooting Stars are spring ephemerals, which is to say, the entire plant disappears after flowering, to spend the summer as an underground tuber. The short period in growth means they are slow to develop. We have been growing ours for three years now and hope some will be up to salable size in time for Mothers’ Day..

New for 2018

Rattlesnake Master Eryngium yuccifolium – odd mace-like flowers.

Closed Gentian Gentiana clausa – a white-flowered garden form, 4-year old plants. You can expect them to flower well this September in a damp spot in your garden.

Ohio Goldenrod Solidago ohionensis – well-behaved, flat-topped goldenrod from moist, calcareous soils, adaptable to ordinary sunny gardens. Pictured above, growing wild along Lake Huron shoreline.

New Plants for Shade

Wild Geranium I have a few of this popular flower for light shade or woodland edge. Unfortunately, many of my small plants of this species have not recovered from the winter. I hope to have more available for the Fletcher Wildlife Garden Sale in June.

Dog Violet A nice little plant for damp shade. Grows from central crown and does not spread into lawns.

Kidney-leaved Violet Grows in shade in damp, shady sites.

White Bear Sedge Carex albursina – an evergreen forest-floor sedge with relatively broad, deep green leaves. Limited supply.

Twinflower Linnaea borealis var. americana – beautifully fragrant pink bells in pairs above a low, evergreen carpet in cool, moist, acidic organic soil. From cuttings.Linnaeus boreale

Some popular and special species which we introduced in previous years will be back again: Dwarf Canadian Primrose Primula mistassinica, Broad-leaved Sedge Carex platyphylla, Blue-stemmed Goldenrod Solidago caesia (a lovely clumping goldenrod for light shade) and American Spikenard Aralia racemosa, among many others.
