Mary Sue, and All, I have a number of dierammas in pots, which dry out between waterings, and they keep blooming. My problem is I've mixed them up, and don't have a decent key. Can you recommend any good references so that I could determine what I have? I know one is probably a dracomontana, and the others are possibly pulcherrimum and pulchellum, or maybe they're hybrids. Thanks, Robin Hansen Dierama, The Hairbells of Africa, by O.M. Hilliard and B.L. Burtt of the Royal Botanic Gardens, Edinburgh, with paintings of each species by Auriol Batten, was published by Acorn Books in Johannesburg and London in 1991. I bought my copy last year at Powell's Books in Portland, Oregon, U.S.A. for $32.50. Diane Whitehead Victoria B.C. Canada
