Greenwood Garden sells a lot of irises, and they are down in Somis, CA, not that far north of Los Angeles. http://www.greenwoodgarden.com... So it can be done. (Be aware that they have renamed at least one iris for sales purposes... they sell 'Rosalie Figge' under the name "Frequent Violet".)
Evaluating an iris seedling, hopefully for rebloom
