The cure for insanity

Cornus canadensis – Bunchberry or Dwarf cornel, creeping dogwood
Native range: Eastern Asia to Far East Russia, Canada, Greenland, Northern USA

We are in for a steamy week ahead; certainly not my idea of great weather. The creeping dogwood also likes it cool. Usually the name Cornus makes us think of trees and shrubs. But this is a lovely perennial dogwood, which grows only to 15-20 cm tall, with leaves arranged in whorls of 4 or 6. The flowers, typical for a Cornus, are easy recognizable after the 4 large, white petal-like bracts. The fruit is an attractive, red, globe-shaped drupe, persistent, and also edible; especially birds are very fond on consuming the fruits during the fall migration.

Among its uses by the Natives Americans I found the mention of fruits consumption as a cure for insanity!

(Maybe I should try to sell fruits instead of seeds – I might get rich; or I can eat them all and have at least my plant-insanity taken care of).

Desirable as a groundcover in any shade garden, where it will form a carpet underneath small trees or shrubs; I have also seen it growing on old tree stumps on top of moss, which would be great to try to ‘reproduce’ in a shady corner. It needs a slightly acidic substrate and a really cool location in part-shade to shade.

Propagation: by seed (difficult germination, but there are protocols available) and division.

Note: Linnaea borealis – twinflower, it was the favourite plant of Carl Linnaeus from when exploring the northern part of Sweden (and the only species that bears his name). A delicate, evergreen woodland plant, with short stems that bear pairs of nodding, pink flowers usually in June. Borealis –‘northern’ refers to its distribution in forests of the northern hemisphere (circumpolar).

      You can give it a try in the fall again by seeds, and maybe I will provide dry berries too for those in need…
      (it really needs a cool, moist spot and improved substrate – anything that would acidify it: pine needles compost, peat)

    Dr. Mosquin described the unusual explosive pollination mechanism of this little gem several years ago in BEN. Check it out next spring when you are poking around the garden or woods.

      Thanks, that’s really interesting! – always something new to learn about…There is a small population in the nearby woods that I can check in the spring (for collecting I have to go a
      bit up north).
