Iris cristata: You Can Grow That!
It grows just a few inches tall and is best suited for the borders of woodland paths and fronts of part-shade flower beds. When not in flower, the narrow foliage is like that of bearded iris, but as it is much smaller, it is hardly noticeable.
The bloom time is late April to early May. It blooms on the previous year's growth, so it will take a year to establish and flower.
It spreads slowly by underground rhizomes. It is easy to divide and share or put in different spots around your own garden. If you want to propagate it by seed allow the seedpods to dry on the plant then break them open over an envelope to collect the seeds.
They are drought-tolerant, trouble-free, and require no care once planted. It does well in rock gardens and on slopes as well.
