Here is a photo — there are actually several whole groups of them that are, technically, partially on my property. They seem to have volunteered as they weren’t there last year and my neighbor does NO gardening whatsoever and, in fact, uses his unit as an office, not a home. The flowers are shortlived but have bloomed consistently all spring and summer.
They are considered an invasive plant here — or so says the internet. Although the ones that straddle my property were certainly not planted, they haven’t run amok but have stayed nicely grouped in an area between my townhome and the next. I think they are quite lovely, especially when the morning sun hits them and the yellow turns a bright gold.
From what I’ve read, many people try to kill them off. I, on the other hand, watered them during the early summer drought we had. Why not? They are attractive and well-behaved.
The internet also informed me that there are more than 850 different species of wood sorrels.
