Beaux Arbres will be bringing plants into Ottawa on Saturday, September 11th. We will be distributing prepaid orders of native plants from a Britannia area parking lot on that Saturday, from 9:30 am until noon. This will probably be our last delivery of plants for the season. The nursery will still be open until the end of September.
Ironweed ($12) and the native hibiscus, Swamp Rose Mallow ($18) are now available and looking very good. We still have seedling Butterfly Milkweeds available — now is a good time to get this much-in-demand species. Many other species are still available. Because some species are available only in small quantities, rather than post a new Availability list, I am asking you to use the August Availability List as a wish list, and I will fill your orders to the best of my ability, in the order they come in.
Beaux Arbres Native Plants has a new Plant Availability List out. We will be bringing pre-paid orders to our regular Britannia area parking lot on Thursday, July 8th, and then, on Monday, July 12th, we will be bringing plants to an address in Navan. Both days the plant order distribution will be in the afternoon, from 4 to 7:30 pm. We expect folks have plans on summer weekends, hence the weekday dates, but we don’t expect our east-end customers to fight the rush hour traffic across town, especially with all the road construction, so we are trying out the new address in Navan.

Customers who come to the farm have often picked up some species which hasn’t made it on to the Availability List because I only have one or two of them in stock. This spring, one lucky customer happened to ask about Hobblebush on the very day I decided that I would never have room for all three of my precious Hobblebushes, so she left with a pot of seed-grown local genotype Hobblebush. Yes, children, that actually happened. So for this issue of the Plant Availability List, I start the list with some of the oddments and singular items that wouldn’t usually make it on. The larger shrubs are things I have grown for our own landscaping and I have been selling off the extras. Once, say, the last Grey Dogwood is gone, it probably won’t be on the list again. The herbaceous items are just things I happen to be low on.
I should point out that the Pearly Everlasting is available with or without resident American Lady Caterpillars, while supplies last. And while we are talking about caterpillars, the Butterfly Milkweed is not yet big enough to include on the list, but it will be on a list coming out soon. They are coming along nicely but not yet ready to plant out.
I have a couple of new things for the Rock Garden: Showy Jacob’s Ladder and Littleflower Penstemon. Not locally native at all, just little cuties from the Rocky Mountains.
Oh, and yes, that Glaucous Honeysuckle vine that I have been promising will be ready any week now — it is ready now and is on the list. Everybody should consider planting a Glaucous Honeysuckle: not too big, two seasons of interest with flowers and fruit, and a host plant for the caterpillars of the charming Hummingbird Clearwing Moths. What’s not to love?
Beaux Arbres will be bringing a delivery of prepaid orders to Ottawa on Wednesday, August 19th, to our west-end parking lot in Britannia. If you would like to order native plants, please download our current Plant Availability list, in either PDF or Excel format, contact us with your choices, and we will get back to you by email with details about the pick-up location and payment options.
We are now accepting sturdy nursery pots for re-use. If you have purchased plants from us, we welcome the return of our 4 1/2″ tall or 2 1/2″ black pots or black nursery cans. In fact, because of lock-down and the provincial border closing, we were unable to get to our supplier of pots this spring, and are now very short of 2 1/2″ pots for seeding for next year. We do not use cell packs or other flimsy nursery plastic.
I noticed some Marsh Marigolds growing in the ditch of the dirt road that runs down the side of the farm. I also knew that the road, which was in rough shape where it slopes down to the creek, was due for some grading from the municipality. So I dug up the clump that was furthest into the road, divided it into four, and potted it up. I should have taken more. Re-visiting after the road work, I notice some of the clumps in the ditch had been uprooted, dragged, and partially covered with gravel. I rescued the roots and potted them.
In the feature photo you can see the original four, in large pots at the back, blooming beautifully. I plan to keep these to collect seeds. The plants in front are in rough shape. A few may recover in time for this year’s sales. Most won’t be salable till next year, if they recover at all.
These are some of the plant I would have been bringing to the Friends of the Farm Mothers Day Sale on Sunday. They are the best looking bunch of plants I have had in the six years since Beaux Arbres first attended the sale.
However, I can bring them into Ottawa for you next week. We are aiming for Wednesday, May 13th, to bring prepaid orders to a west-end Ottawa parking lot.

Some of the seeds I have in very small quantities, perhaps because that was all I was able to harvest, or sometimes because I think the plant is a bit specialized and will be attractive to only a few gardeners. Tall Coreopsis (Coreopsis triptera) is one such. It is a nice, easy, tall yellow daisy, but the number of gardeners who need a 7 foot plant which runs is limited. However, if you have an expanse of Big Bluestem Grass (Andropogon gerardii) and want to add colour and diversity to your fledgling tall-grass prairie, Tall Coreopsis would be just the thing. If you want a tall yellow daisy which very much stays put, I have seeds, new this year, of Compass Plant (Silphium laciniatum), tap-rooted, with elegant leaves.
Another species I have only a couple of seed packs for is Fen Grass-of-Parnassus (Parnassia glauca). Everybody loves this little charmer when they see it in bloom, but I have to warn you it is both fussy to site and very, very slow from seed – a species only patient and experienced gardeners should attempt from seed.
Lead Plant (Amorpha canescens) is a lovely summer-blooming little shrub in the Pea family. It is slow to mature but otherwise not difficult to grow in a dry, sunny spot. Each pod has only one seed, and the hard, tightly-wrapped pods must be removed for the seeds to germinate. I suspect that folks who have had difficulty germinating this species were not using hulled seeds. I go at a small heap of the pods with a heavy marble rolling pin and some elbow grease. Some of the seeds get crushed in the process but I do manage to release many seeds. I have had great germination success with seeds I have prepared this way and now offer for sale. Lead Plant is so slow and tap-rooted, it almost never appears in the nursery trade, which is a shame.
Dwarf Mountain Fleabane (Erigeron compositus) is a charming species, easy to geminate and easy to grow. I think anyone with a rock garden might like to have this little mat-forming daisy in quantity. It grows in the Canadian Rockies and also across the north to the Atlantic. It seems to be tolerant of the hot, humid summers of the Ottawa Valley.

A few species want such a long period of cold-moist stratification I have put them in little bags with moist vermiculite and they are already (December) in my fridge: White Turtlehead, Dwarf Arctic Iris, and Beach-head Iris. If you take any of these home from Seedy Saturday in March, you can place them back in the fridge until you are ready to sow them, probably when it starts getting warm about the beginning of May. Alternatively, you can sow them and place their pot outdoors to experience natural winter temperature fluctuations.
Although it is quite common in woods and hedgerows, this native honeysuckle is known to few gardeners.
Glaucous Honeysuckle’s red tubular flowers with yellow anthers, in mid-spring, have the same colour scheme as the much better known Wild Columbine, and it should come as no surprise that ruby-throated hummingbirds are the pollinators it has evolved to attract. The buds are a deep, dark red. This seems like it should be an exciting colour but, in fact, dark red is quiet and hard to spot in the landscape. This may be part of the reason why this vine is so little known. As well, the flower clusters, and the berry clusters which follow, are often partially hidden in a cup formed by the uppermost pair of leaves. The bright red fruits, which ripen in early summer, are, like most soft summer fruits, taken very quickly by birds.
I am amused by the joined, or perfoliate, pairs of leaves, around the flower clusters — they remind me of the Tin Man’s hat. This is a nice vine to plant to by a sitting area, to enjoy the intricate flowers, and their hummingbird pollinators, close-up.
The botanical name for Glaucous Honeysuckle is Lonicera dioica. Dioica as a specific name, should mean that the plant is dioecious, i.e with male flowers and female flowers on separate plants. However, Glaucous Honeysuckle is NOT dioecious. Botanical names are assigned by whomever describes the species first, not necessarily by accuracy.
Glaucous Honeysuckle is a twining vine. It does not have tendrils or other clinging mechanisms. In the wild, it is often found growing as a shrub-like sprawling jumble. Give it a trellis or other support and a tiny push in the right direction, and it shows off its limber and obliging nature. (Limber Honeysuckle is an alternative common name in the U.S.) It is not a tall vine, topping out at about 2 m.
My first encounter with this charming little native primrose was on the wave swept shore of Lake Huron, on the Bruce Peninsula, where limestone pavements shelve incrementally down to the water’s edge. Nestled in tiny, moist cracks in the limestone, never far from the spray, were some small pink flowers with yellow centres, Primula mistassinica. I have since encountered this plant in other locations in eastern Canada, almost anywhere there is damp limestone, such as in seepage areas on limestone cliffs. Primula mistassinica is named for Lake Mistassini, the largest lake in Québec.
Brought into the garden, this little primrose flourishes and has many more flowers in each cluster. The buds form the previous year, visible but nestled deep in the basal rosette of leaves, and ready to bloom very early in spring. This is a charming little plant for a damp spot in a rock garden or a trough.
When I initially encountered Primula mistassinica, I called it Bird’s Eye Primrose. I have since learned that that name is perhaps better reserved for a very similar species, with a slightly more eastern distribution, Primula laurentiana, and P. mistassinica should be called Dwarf Canadian Primrose, although getting folks, including me, to alter the common names they learned in childhood is not an easy task. From their written description, I find it difficult to know exactly how the species differ. I decided the thing to do would be to grow them side by side. I was able to acquire some wild-collected Bird’s Eye Primrose seed, from the Ontario Rock Garden Society Seed Exchange, in 2018. The little P. laurentiana seedlings have not yet bloomed for me, and, honestly, did not look that different from P. mistassinica for most of the summer. However, by November, there were some differences apparent: Bird’s Eye Primroses have fewer and broader leaves and they are less persistently evergreen, as we can see in the photo below. Both plants have buds in their centres, ready for next spring’s early bloom.
While active outdoor gardening is on pause, this is a good time to introduce some wildflowers which may not be known to most gardeners in the Ottawa area.
These flowers may be unfamiliar because they are not native to the the Ottawa Valley, but hail from further south in the USA, as does today’s species, or, perhaps, from the tall-grass remnants from the extreme south west corner of Ontario. Species which are not locally native are obviously not appropriate for ecological restorations. But for gardens? There are arguments for and against restricting your gardening choices to locally native species, which we will leave to another day.
Another reason wildflowers may be unfamiliar to gardeners is that they are confined to highly specific habitats such as alvars or fens. Or they may be diminutive and easily overlooked until they are brought into cultivation in rock gardens and troughs.
Downy Skullcap, a fine border plant from the eastern USA, contributes nice blue colour and distinctive flower shape to the late summer garden. The summer leaves are edged with dark purple. Purplish pigments suffuse the leaves in the autumn.
Some other Skullcap species do occur in the Ottawa area: Marsh Skullcap (Scutellaria galericulata), the curiously named Mad-Dog Skullcap (S. lateriflora), also found in damp areas, and the diminutive (S. parvula) , which grows on alvars, including Ottawa’s Burnt Lands alvar. They all have blue flowers with the distinctive skullcap shape. Closely related, Downy Skullcap is suitable, in showiness and in size and in growing requirements, for a place in a perennial border.
On a dreary November day, with the golden tamaracks providing the only colour in the landscape, the interior of the hoop house is only a couple of degrees warmer (still quite chilly) but colourful fall leaves still linger. The brightest colour comes from the leaves of Wild Geranium. I like the green and red carpet of Prairie Smoke. The lovely soft apricots of Bowman’s Root have mostly faded to brown but one plant is still glowing.
