Xanthorrhiza Simplicissma, my entry for the letter X.
Also know as Yellowroot and I wouldn’t be at all surprised if Paige doesn’t have some of it growing in her neck of the woods. Common and easy to propogate we know that it flourishes on both sides of the pond (your local pond and the one the Queen of England sometimes crosses.) I wondered how I was going to pull off an entry with a real link to the letter X. John Bartram wouldn’t have been the least bit surprised. (Although his specimen would have been a bit fresher, but not so long lasting.)
X just went out a couple of days ago. It was accompanied by R and Q. R, Q & S coming next!
