Scouting around for ways to delight and engage you, I stumbled on a blog entry at Gardening Gone Wild about one woman's love affair with an unfamiliar but very handsome tree. End result: Disaster.
Turns out the tree is one a friend of mine is jonesing for: Robinia pseudoacacia 'Frisia'.
So this got me wondering about the gorgeous plants I've fallen for that I'd NEVER plant again.
My opening bid: A euphorbia named 'Portuguese Velvet', with the nicest euphorbiaceous foliage I've still ever seen.
Four years after ripping it out, I am still pulling out at least 100 seedings/season, AND, I'm now seeing runaways in gardens down the street.
