These Trilliums have been here for 13 years since they were rescued from an area in Kanata that was to be developed. There were 6 flowers this year, about the same number as I started out with but there are a bunch of plants with small leaves so maybe in a year or two if the rabbits don't take an interest there'll be more. For the past few years it seems like one gets felled each year by a rabbit that has to relearn that trilliums don't taste good. This year the rabbit ate half the flower bud from one plant, which is at least better for the plant than taking it down at the stem.
This year I removed some buckthorns from around these trilliums in order to give them a bit of light. I've recently learned that European Buckthorn is alleopathic, meaning they produce a chemical that supresses the growth and germination of other plants, so I've become much more willing to intervene and remove the buckthorn. I've noticed that buckthorns are pretty effective at suppressing grass. Where they form the edge of the forest the grass dies back from under the bushes. Other trees and bushes are not nearly so effective at keeping the grass at bay; for instance grass can happily grow under sumac.
This flower is Creeping Charlie, an invasive from Europe. I planted this patch, inadvertently, about 6 years ago when I planted a black locust in the 2009 area. In contrast to the trilliums, the creeping charlie is spreading quickly as a dense mat in the shade of the blacklocust. That part of the 2009 area still has grass although the black locust is growing quickly. I expect the creeping charlie will eventually disappear when the grass loses out to trees and bushes. Creeping Charlie seems to like growing in tall grass (there is more of it on the north side of the berm in the long grass) but I've never seen it growing in a proper forest's leaf litter.
