September is a good time to plant native wildflowers in your garden. It is an especially good time to add spring-blooming natives such as pussy-toes, columbines, and violets, if you want to increase wild-life attractiveness and spring colour for next year. These early bloomers grow well in cool soil so even with cooling night temperatures, they have plenty of time to root in well and prepare for lots of bloom for next year.
Pussytoes, both the low, creeping field pussytoes (Antennaria neglecta) and the slightly larger plantain-leaved pussytoes (A. plantaginifolia) are host (food) plants for the caterpillars of American Lady butterflies. American Ladies are strong fliers and mama American Ladies are well able to find new patches of pussytoes, even in seemingly inhospitable city gardens.
Violets are also key butterfly food plants. The diverse native species of violets are the hosts for the caterpillars of the several species of Fritillary butterflies. We often see the small Meadow Fritillaries checking out the Canada violets which are growing in lower dampish bits of lawn at the bottom of our garden. And, yes, Canada violets are the aggressively spreading violets which will seed themselves in lawns. We have them in both purple and white form and we like the way they create a floral carpet in that part of the lawn. However, I can quite understand that not everyone wants this effect and why some people are wary of adding Canada violets to their gardens.
We also offer other species of violets, some of which are anything but aggressive spreaders. We have two species of violets for open, sunny, dry places: Bird’s Foot Violet (Viola pedata) and Hooked-spur Violet (V. adunca). They may be especially attractive to the large and glamorous butterfly called the Great Spangled Fritillary, a creature which likes warm, sunny places. Hooked-spur Violet is also called Early Violet and it is a lovely low, early bloomer for rock gardens. Bird’s Foot Violet is a very special species from Carolinian Ontario which has relatively large flowers and which will rebloom in summer. It is an exceptionally nice flower for sunny rock gardens.
September is a good time to plant shrubs. Beaux Arbres carries some of the smaller, decorative native shrubs and this year we are well supplied with Pasture Rose (Rosa virginiana), Sweet Fern (Comptonia peregrina), Purple Chokeberry (Aronia prunifolia), and Kalm’s St. John’swort (Hypericum kalmianum). The last one, Kalm’s St. John’swort, is a Great Lakes indigene which also occurs in the Ottawa Valley. We are proud to be able to say our Kalm’s St. John’swort is grown from seed collected here in Bristol Township, Quebec.
Beaux Arbres Native Plants has these and many other species of wildflower in stock. We are open until the end of September. Come and visit us soon.
