This cheery little flower is an under-appreciated Ottawa Valley native. Along with its early-blooming companions in the wild, such as Early Saxifrage, Prairie Smoke and Hooked-spur Violet, Early Buttercup (Ranunculus fascicularis) is a great choice to provide floral resources for newly emerged pollinators. Early Buttercup is a true spring ephemeral — the plant withers into dormancy shortly after the seeds ripen in late spring. The leaves re-emerge from the somewhat tuberous root almost as soon as the snow is gone the next spring.
Early Buttercup grows wild on only one alvar in the Ottawa Valley. It is more common on the alvars of central Ontario. Beaux Arbres’ stock of Early Buttercup was grown from seed collected in the Ottawa Valley, i.e. it is local genotype.
Early Buttercup occurs in the wild only on alvars and similar open, calcareous habitats. This gives us a clue to what it likes in the garden: full sun, sweet soil, and not being crowded by larger neighbours. Like other alvar inhabitants, it is tough, adapted to heat and cold and spring wet, and its summer dormancy allows it to endure the droughts of summer.
I am making an assumption, on this snowy day in January, that I will have Early Buttercup available in the spring of 2021. We went into the winter with a good supply of seedlings. However, I have had unexpected winter losses in the past, and I am never totally sure plants are available until I see them start to grow in the spring. I will be posting Availability Lists in the spring, as growth resumes.
