Nursery contributed plant descriptions

Plum scented Iris, clumps of 8-12" slender leaves, blue violet flowers on 4-8" stems down in the foliage. Tolerates dryness and is suitable for large rock gardens. ZONE 4

By: Arrowhead Alpines

Bright red/purple flowers held barely above the foliage. About 15" tall overall. Sometimes called grass leaved iris which is a very good description. Zones 5-8. Full sun to part shade. Tolerates dry conditions better than some irises and may like a sandy soil. Fragrant.

Thanks to garden designer and Maven of Taste Madeleine Wilde for sharing this deservedly popular Iris with us. Evergreen grassy foliage and distinctive narrow petaled Art Deco purple flowers which beckon from within the foliage. But it is the haunting scent of Green Gage plums.......
