Gardeners' Notes:

The Royal Horticultural Society has granted this species its prestigious Award of Garden Merit.

The leaves do make it look like a miniature corn plant or a daylily fan. Personally, I feel it has more foliage than the flowers warrant, considering how short the bloom season is and how messy the leaves look dying back in late spring. But many people like the look. Prefers to be kept dry during summer dormancy.

Easily available from fall bulb dealers, and it perennializes well here (Massachusetts).

This is the most wonderful little Iris! It blooms in late April for me. The yellow is a clear lemon yellow, never tending to gold. From 5 bulbs planted in 1999 I have split it once for myself, and given some away to a friend. The blooms last for a week or more.
