| Maintenance | Divide the plants in August to September into clumps with at least 3-5 eyes. Fan back the foliage 50% or more. Older plants become more difficult to divide because of the deep fibrous root system and as they age the plant forms a solid mass of white roots. I was talking to a gal that runs a small perennials nursery and she uses a small reciprocating saw for dividing old clumps |
| Propagation | division |
| Cultivar Origin | Forrest McCord, Indiana, USA (1972), across between Siberian Iris Tycoon and Grand Junction (www.allthingsplants.com) |
| Author's Notes | If you are looking for a perennial that will live forever, Siberian Iris are about as close as you can get. Out pf bloom the plant has a nice vertical structure of cattail like leaves. I have been growing Siberian Iris Halcyon Seas since the early 1980's. |
