■(TB) 'Plicata' (wrongly called 'Swerti' by Farr)

In cultivation since at least 1590

'Plicata' Collected or garden Hybrid, Jean-Baptiste de Lamarck, 1789), TB, Midbloom season. Color code=W8; Color white with a blue edging. Its name (actually meaning "pleated") has become the name for this color form. Considered to be a natural or garden hybrid, or possibly a color form of Iris pallida. Originally called "white iris with blue edges" (alba iris oris cæruleis) it was first described and named in Lamarck's Encyclopedia 3: p. 294 (1789). In cultivation since at least 1590 (in "Le Jardin du Roi très chrétien Henri IV"). The "pleated iris" was first described as iris aphylla in Curtis's "Botanical Magazine" then correctly renamed iris plicata.

Note - A confusion has arisen between iris plicata and iris swertii since Farr's catalog gave them as synonymous.
