1) Tom Cothier's Website:
a) "Impervious seed coats. Shake in dry sand or nick carefully with a file.
b) "Sow at 18*C - 22*C (64*F - 71*F) for 2 - 4 weeks, move to -4*C to +4*C (24*F - 39*F) for 4 - 6 weeks, then move to 5*C - 12*C (41*C - 53*C) for germination."
2) from: Ontario Rock Garden Society website:
a) As in Clothier #1a - "Requires scarification. Nick or rub between sheets of sandpaper."
b) "Requires soaking. Place in warm water until seeds swell, usually 24 - 48 hours."
c) i) "prechill 4 weeks, or
ii) expose to fluctuating outdoor winter temperatures including freezing for 3 months.
d) Gradually increase light and temperature in spring, [which can be done by bringing] indoors once germinated to avoid temperature shock.
e) Transplant at 4 leaves."
In #2, the Ontario Rock Garden Society also offers another germination method which is similar to Clothier's method in #1 and may be best for fresh seed. Personally, I'm inclined to go with the technique that involves prechilling since my seeds are not fresh.

Beautiful little plant. Quite hardy and vigorous here (zone 5a). Flowers placed a bit low among leaves.
Hardy in zone 3; also called "plum-scented iris".
