It is not too late to order plants for pick-up at the Westboro Ottawa Farmers’ Market on Saturday. Please get your order to us by noon on Friday as we load up the trailer Friday afternoon. Order Plants.
We are out of many popular species until next year. No more Butterfly Milkweed, Ironweed, or even Large-leaved Aster. However, we still have lots of plants available – little known species such as Ditch Stonecrop, Whorled Milkweed, and Goat’s Rue. We have some great native vines available: Purple Clematis, Virgin’s Bower, Canada Moonseed, and Hairy Honeysuckle. The latest Plant Availability list is up on the Order Plants page.
Native vines, and where to get them, have been much discussed this summer on some native plant Facebook pages I follow. Beaux Arbres has a fine selection of native vines for the Ottawa region.
One of my favourite vines is the Glaucous Honeysuckle. Unfortunately, I forgot to collect seed from this species last year. To have some Glaucous Honeysuckle available, I layered some stems of the plants in my garden. I have only a couple of these starts left. I do have a good supply of Hairy Honeysuckle, grown from seed. Hairy Honeysuckle is similar to Glaucous, but the flowers are yellow rather than red and it flowers a little later.
Canada Moonseed (featured image) is not well known but it is a good vine for shade. The flowers are tiny and hidden in the leaves. If the plant is female, and there is a male nearby, the flowers will be followed by dark blue fruit. Leave these for the birds – the seeds should not be eaten by people. Canada Moonseed has attractive lobed leaves.
There are two native Clematis in the Ottawa area. Virgin’s Bower is a large vigorous vine, adorned with a froth of small white flowers in late summer. It flowers best in a sunny locations. Much less common and much less known, Purple Clematis has large nodding blue-violet flowers in spring. It is found in the wild in woods, but it flowers more abundantly in gardens if it has at least half-day sun. Both vines have attractive seeds heads after their flowers. Now that I have a few Purple Clematis established in the garden at Beaux Arbres, I have easy access to a supply of seeds of this elusive species, and I now have a good supply of young Purple Clematis available.
American Bittersweet is, like Canada Moonseed, dioecious, that is, it has male and female flowers on different plants. Some years ago, I grew some American Bittersweet from locally collected seed, and I still have a few pots left. This plant will not flower when dwarfed by being kept in a pot, and there is no way to tell if it male or female until it flowers. Most folks, quite understandably, want a known female, since it is the bright orange fall fruit which is the decorative feature of this vine. The oldest and largest specimen in the garden at Beaux Arbres is a female and it has produced a couple of suckers. Drop me a line if you are seeking a female American Bittersweet, and I can pot up a sucker off our known female.
We grow two herbaceous vines, the dainty biennial Allegheny Fringe, and new this year, the intriguing American Groundnut. We were generously given some garden divisions of Groundnut by a loyal customer and I am propagating it from the roots. For centuries, American Groundnut has been vegetatively propagated by Indigenous people in eastern Canada for its edible roots, so this is one species where I needn’t worry too much about maintaining genetic diversity through propagating by seeds. The tubers of American Groundnut are delicious roasted.
There is one more native vine which I would very much like to be able to offer: Carrion Flower. I have tried several times to start this handsome herbaceous vine from seed but have never been successful. I would love to hear if anyone has been successful in germinating Carrion Flower.
We could meet in a parking lot, wearing masks. Not necessarily at dusk, and I don’t know if I could hide the clematis under my overcoat, but the new retail normal is … odd.
I have one pot of the native Purple Clematis (Clematis occidentalis) still available of the plants from my original seed collecting. I now have this species established in my garden, but it will be a few years till I have mature plants available for sale again. This is a woodland clematis with large (for a wild clematis) purple flowers in the spring. Native to the Ottawa Valley but not at all common. It is much more restrained in growth than the abundant white-flowered Virgin’s Bower (C. virginiana). The individual plant I have for sale is 4 years old and has abundant flower buds.
I also have two pots of Fremont’s Leather Flower I am willing to sell. I raised 5 plants from seed from the Ontario Rock Garden Society seed exchange. Now, I do like to keep at least 5 plants of unusual species that I hope to collect seed from, but Fremont’s Leather Flower is one of the limestone-loving Clematis. A realistic assessment of the space I might someday have in my yet-to-be-built limestone garden (realistic assessment is a hard task for plant lovers) suggests I am never going to have the space for 5 Fremont’s Leather Flowers. So I am keeping only three.
Fremont’s Leather Flower is a non-vining Clematis from the south-eastern US. it has dangling white or lavender urn-shaped flowers in June on a clumping herbaceous plant about a foot and a half high. In the wild it is found on dolomitic glades and limestone prairies
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.
