I don't know what the florists have, but here in California I'd say it's a blue(ish) holiday because I'm inundated in Moraea polystachya. I have about six pots of them, and this year I remembered to start watering them in August. They've been in bloom for more than a month, and are still going strong. They don't seem to establish themselves well in the ground so far, but I'm still trying. Mike San Jose, CA (zone 679, min temp 20F / -7C)
