#Blueweed #meadows fascinate me. The #flowers of blueweed rise from red bulbs into blue #blossoms (attached photos), and they ripen in two steps, first the male parts become fertile, only then the female parts, a phenomenon that is called #proterandric. The species is used for #greenroofs, important in #globalwarming times, see paper of authors A. Latini et al. (2022).

Blueweed or viper's-bugloss is both poisonous and a medicinal plant. I guess it all depends on the dose. So don't play with it. It's also considered invasive in a lot of areas. they could all be noxious weeds but it's a fun plant to draw. It gets 1 to 3 feet tall.
