Dear Jim, I want to become a Chinese herbalist! I intend to get Iris anguifuga, but I don't want to keep snakes away, I like having them in the garden. Too bad the mice don't; I only wish they got hungry oftener. Now, how to say it kindly and gently: "This species has been grown by Chinese herbalist for centuries, but never brought into cultivation until..." That's what an English boy would say! I've said it myself. I've said I introduced Rosa achburensis to cultivation, when what I meant was I introduced it to cultivation outside Central Asia. I said it more accurately in letters and catalogues, but more loosely in conversation. E-mail is more like conversation. Best, Don
