Jupiter's Beard, centranthus ruber. It's pretty, the bees love it, it's drought-tolerant, wet-tolerant, loves any kind of soil, is easy to grow and it must go. It reseeds prolifically and it's a thug, I tell you. There are hundreds of new baby plants all over the garden crowding out the things I love like dianthus, penstemon and clarkia. I've enjoyed all the centranthus I can stand and now it shall die. Gotta get it out before it seduces me by blooming.
It has rained (and rained & rained) and the soil is soft so I'll be out digging up large, stinky centranthus tubers. Walk a wide berth. See ya when it's over.
(It might get to live in the back yard where it can't get loose on the neighborhood.)
