O.K.,
One last thing that I wish I'd done...
I'd suggest you keep good notes on your plants. It's kind of a pain to set up at first, but I have a map of the beds, the names of the plants, when I planted them, when the problems showed up (and if there was an obvious reason (late frost, mormon cricket swarm, rabbits)), and what bloomed well. The one thing I didn't realized was that the iris from different hybridizers perform differently (are zone tempermental?) in different areas of the country. For example, a Blythe iris may do well in Ca., but not so much for me, or vice-versa. When the next storm hits this weekend I'm going to go back through and note each hybridizer with each iris.
