The Dwarf Rockgarden Iris, Iris, is fragrant, low growing and early blooming. They multiply rapidly and are excellent for borders or rock gardens, under shrubs and trees, in beds, borders, and containers and for indoor forcing; needs a well drained soil. Blooming very early spring, Dwarf Irises typically bloom after Snowdrops, but before Giant Dutch Crocuses. They have relatively large (iris-shaped) flowers on a short stem.
