Iris unguicularis

Algerian Winter Iris

USDA Zone: 8-9

Plant number: 1.289.320

(Formerly Iris stylosa) Totally unlike any other Iris species, this is a winter-flowering plant. Best suited to mild winter regions, such as the west coast or Gulf States. The grassy foliage forms an evergreen clump, with fragrant, soft lilac-blue flowers produced among the leaves from November through to March. Prefers a hot, sunny site on the dry side, particularly against a wall or house foundation where the extra protection will help to keep away untimely frosts. Resents being disturbed, so divide or move only when absolutely necessary, in late summer. CAUTION: Harmful if eaten.
