Discussion | Iris purdyi hybridizes with I. bracteata, I. chrysophylla, I. douglasiana, I. innominata, I. macrosiphon, I. tenax, and I. tenuissima. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Iris fulva hybridizes with I. brevicaulis to produce I. ×fulvala Dykes, which has reddish purple sepals; with I. giganticaerulea to produce I. ×vinicolor Small; and with I. savannarum to produce I. ×cacique (J. Berry) N. C. Henderson. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
