We live in an old neighborhood—our house was built around 1915—and many seeds and bulbs and shrubs have come and gone. Last year, I fenced the witch hazel against the deer. Maybe someone planted strawberries here a long time ago, and they had been lying dormant in the yard until, this year, they had enough protection from deer and groundhog predation to reemerge. Welcome back, strawberries.
I am fascinated with volunteer plants and plant migration. We think of plants as stuck in place, but in fact they are constantly traveling. In my LiveJournal blog on May 14, 2007 [http://refwhiz.livejournal.com/], I wrote about two other plants that appeared in our yard:
Three years ago a few common milkweed plants (Asclepias syriaca) appeared in a marginal location, right next to the street curb in the midst of a forsythia. Last year they expanded to the south, downhill, under a Norway spruce. This spring they ring the very edge of the area under the spruce, right up next to the curb and the neighbor's driveway pavement. I counted 26 young plants this morning. The soil in this area is very dry—the spruce sucks up most of the moisture. Somehow the milkweed has found a foothold, right on the very edge. I like this because milkweeds have beautiful flowers and seeds; I didn't plant them, they volunteered; they are native plants; they occupy territory where little else will grow; and they are essential food for Monarch butterflies. Another big volunteer this year is gill-over-the-ground (Glechoma hederacea).And flourish they have. In this, the fourth year after the milkweed plants first appeared, we have over 50 milkweeds and more Monarch butterflies. The volunteer gill-over-the-ground continues to spread. We also have two new spruce seedlings (probably white spruce) that we are thinking of transplanting into the side yard as a windbreak. Jane found the first spruce volunteer under the hose outlet in deep shade right next to the house. It was scrawny and about six inches tall. She moved it out into partial sun and, after about seven years of growth, we harvested it for a Christmas tree.![]()
It is making a lovely low ground cover in the beds of the backyard and is covered in delicate, tubular blue-violet flowers. These volunteers come when they wish, stay only as long as they want, and leave on their own schedule. May they flourish, both of them.
Last year, our first volunteer thistle sprang up from a tiny dribble of soil between the base of the stone wall under the kitchen garden and the driveway asphalt. It grew 64 inches tall, with over 60 flowers, each a spiky mass of saturated pale violet, and attracted a lot of bees. Using Peterson’s Field Guide to Wildflowers, I identified it as a
bull thistle (Cirsium vulgare).
Once it began to go to seed, a pair of goldfinches showed up to eat the seeds for weeks. The thistles are back this year, growing from last year’s seeds, and now there are four. Yes!
Besides feeding the birds, some of the volunteers feed us. We have harvested horse mushrooms (Agaricus arvensis) several times out of the side yards. They fruit sometimes after heavy rains in the spring, summer, or fall. Our other main mushroom volunteer is not so benign: tippler’s bane (Coprinus atramentarius), so called because it causes “alarming symptoms (nausea, palpitations) when consumed with alcohol” (Roger Phillips, Mushrooms of North America). We don’t eat them.
And, there are plant volunteers that I harvest for the compost: plantain, dandelions, the dreaded garlic mustard, and creeping bellflower. We pick and choose which plant volunteers to befriend. But I am always interested to see who will show up next.
