On shrubs and subs

In the cities, we plant floral borders to our walkways. Alongside our human paths in the deep forests, where we've cleared away the duff and rotting branches, the borders plant themselves. Seen this trip; lichens and mosses, wild strawberries and the tiny native trailing blackberry, vanilla leaf and wild columbine. And the tiny twinflowers and tidy bunchberries.

Twinflower, Linnaea borealis

These little flowers stand less than 4 inches tall. I went through my guide to wildflowers twice, page by page, from lilies to broomrape; the twinflowers weren't there. I checked the index, which I should have done first, but never do, and there they were, among the shrubs.

I always think of shrubs as being larger plants, smaller than trees, but at least knee-high. And the twinflower doesn't look shrub-like. But a shrub is defined as a woody plant, usually multi-stemmed, usually under 20 ft. tall. No lower limit.

The twinflower has woody stems, but they trail along the ground, sending the short flower stalks up into the light above. Each stalk ends in a Y, and bears two bell-like flowers. Look at the photo above; a half-dozen or so "clappers" dangle below their "bells". The leaves are evergreen, to match the forest above.

Bunchberry, Cornus canadensis, aka Dwarf dogwood. With twinflower for size comparison.

If the twinflower is a shrub, why isn't the bunchberry? It has trailing, somewhat woody stems, is in the same genus as the Pacific dogwood, a tree, and the red-osier dogwood, another shrub. Maybe it's that the stems are only somewhat woody. Wikipedia calls it a subshrub.

The actual flowers are small, greenish yellow, with purplish centres; four bluish white bracts at the centre of the leaf whorl upstage them, at least to our eyes. The bees aren't fooled.

The leaves are semi-evergreen, and the fruit is a red berry, edible, they say. I haven't tried them. Yet.

Hints of spring already

This afternoon was unseasonably warm, and not even raining, so I took the chance of doing a bit of gardening, intending mostly to cut out plants that had been killed by the sudden, extreme (for here) cold spell in December. Cutting down the first one, I found new green leaves sprouting at the base. The next was better still, with flower buds forming already. And the next ...

All I had to do was clean away dead leaves and stems, and the garden is a garden again.

Hellebore bud. This one, last year, was a deep purple. It may darken as it grows.

Of the evergreen perennials, the primulas and pachysandra are already in flower; the hellebores are well on the way. The sausage vine and the bergenia which had seemed to be dying are back to normal; the salal and heather, sweet William and, of course, the London Pride, don't seem to have noticed the crazy weather. A half-dead Epimedium that I transplanted last fall seems to have been invigorated by the chill; it's better now than it ever was.

And this was completely unexpected; an Italian parsley plant that I planted as an annual, didn't protect from the cold because it was due to die anyhow, and left exposed in the coldest part of the garden, barely lost a few stems and still fills its pot, still green.

The Dutchman's breeches are poking out of the soil, and the bare twigs of the hydrangea all boast a big bud at the tip.

All this makes me happy.

A hanging pot off in a corner, where I'd planted trailing nasturtiums and lobelia, and which had housed a volunteer fringe-cup a couple of years ago, was a complete mess, a tangle of old twigs, cedar droppings, and dead, crispy stems. I cleared it all out, and found the fringe-cup coming back underneath. The usually green leaves are red, probably because of the cold.

Fuzzy stems and leaves of the fringe-cup.

A closer look at the stem. A bug would call it spiky, not merely "fuzzy".
