Given there are only two species and both resemble Iris, this is a fine plant for the garden. Understand though that this is a short-lived plant. And while it is lovely with its delicate flowers, it is only expected to last 3-5 years before it dies. You'll have to learn to propagate it or continue purchasing the plant.
How To Grow
Grow this plant in the full sun or very light shade.
Grow in a well-drained soil, it doesn't appreciate wet feet or clay.
Feed moderately, a shovel of compost in the spring is adequate.
Protect over the winter if you live in a USDA 5 or colder. I've overwintered it quite successfully in a USDA 4 with no protection. (But it only lasted 3 years)
In short, treat it like a tender iris.
You can divide this plant in the early spring or fall to produce offsets. Get a bit of the root with each fan of leaves and division you take.
By seed. In the fall, the seed pods turn brown, split open and there are shiny black seeds inside. Take these and treat as for any perennial seed. They are relatively easy to start from seed although they will take 2-3 years to flower from successful germination if grown properly.
Easy and delightful plant to grow but do keep dividing it every two to three years to establish a clump of them. Otherwise, you'll lose this short-lived plant from your garden.
