Well, my pots are in a little more protected area where they get a little less sun than the beds, so mine, bloom pretty close to on schedule. They do decline after the first year, and I try my best to get them all planted before then.
When I first started pairing Iris with other Iris, I neglected to check bloom times... Mistakes were made
With the beds I've planted this year, I'm going for the big bang and trying , for the most part, to get colors and bloom times compatible. We'll find out this spring.
Neal, I'm so glad I'm not the only OCD person here with color.. Drives me nuts when I get it wrong.
That said.. It seems like pictures I've seen where they're randomly planted in mass, can be striking too..
