A bulbous Xiphium Iris from Southern Europe.

Has lance shaped light - mid green leaves. Bears deep blue to lavender, occasionally yellow or white flowers with a yellow or orange marking on the falls.

Flowers April to June

Loves a well drained, moderately fertile soil in full sun. Don't allow the bulbs to dry out completely when dormant.

This species is one of the parent plants of the many Dutch Iris hybrids.
