That is, I planted it last spring, expecting it to bloom sometime during the summer. Not only did it not bloom, it did not even sprout until last winter. By that time I had given up on it altogether; and in fact, I ignored it when the leaves came along, looking rather like miniature gladiolus swords.
Then, a couple of weeks ago, it bloomed.
I think the schedule of my particular corms was entirely upset when they first arrived. The supplier (McClure and Zimmerman) is in Wisconsin, and it is a bit difficult to sync good shipping times between the two climates, especially for spring planting. Autumn planting would clearly be a better choice where winter temperatures permit. It is said to be hardy to about -10 F (-23 C).
All the plants that bloomed had flowers of creamy-white with a dark blotch at centre. So much for "mixed" colours, but they are quite attractive anyway.
