■(TB) 'Catalyst'

1980, Keppel

'Catalyst' (Keith Keppel, R. 1979). Seedling# 75-83A. TB, height 35" (89 cm), Midseason bloom. Standards sunflower (M&P 9-L-4) touched with golden glow (9-L-6) at base; Falls darker, velvety yellow; yellow-orange beard. 'Generosity' X seedling# 72-5B: (((('Frances Kent' x 'Mary Randall') x (seedling# 60-183-Q: Sexton seedling# 60 x 'Golden Gene')) x ('Denver Mint' x seedling# 60-183-0)) x ('Radiant Light' x ((('Golden Gleam' x 'Hallmark') x (Sexton seedling# 60: 'Gail' x 'Techny Chimes')) x seedling# 60-183A))). Keppel 1980.

Some want to classify CATALYST (Keppel '80) as intense yellow rather than gold, but this one seems every bit as gold as the others. Regardless, CATALYST seems to have everything an iris should have, with ruffled flowers on widely branched tall, multi-budded stalks. (Kenneth Mohr, 1983. AIS Bulletin, July 1983, p. 35).
