White bedstraw: it doesn’t take an expert to guess that it’s closely related to the lady’s bedstraw as featured in a post yesterday. Both were flowering at the same time earlier this month in the wetland / wildflower area around the Compton Park pond.
It seemed to me that the lady’s bedstraw was the more strongly perfumed, though that impression may have been because there was quite a bit more of it, and it was easier to get up close.
