LONDONDERRY: (Keith Keppel, R. 1995). Sdlg. 91-41C. IB 24" (61 cm) EM. "S. and style arms pastel pinkish lilac (M&P 42-B-8); F. same, paling to near-white center; beards cool white, lightly tipped lemon and tangerine in throat; ruffled. Gatty T-1-2: ((Nefertiti x Playgirl) x Presence) X Chanted., Keppel 1996. HM 1998" This information was taken from the American Iris Society Check List Data Base. This IB is a pale, silvery pink color, which has a soft pastel appearance and shows a very faint lavender mauve influence. It is a real stand-out in any part of the garden. It grows here in a perennial bed along a path. It is very, very vigorous, and blooms cover a two-year clump. Nice!
