I didn't get what I bought but person has offered to send replacement. Is there a reason why I should or shouldn't plant now?

The vendor will probably send the replacement in summer. I've heard iris can be moved in spring, but I don't know how well it would do in Texas.

If you plant it, make sure to give it a lot more water than you would otherwise give to your bearded irises. I think I would pot it up, so it could live in the shade for a while. Not sure a Texan summer in full sun would be good for it.

Irises are resilient, so it should live. I agree with the others, you should pot it up and place it in the shade until fall cooling sets in and water fairly regularly.

Irises tolerate heat, but too much will dry them out.

I had an iris or two on my porch in full sun during summer, and realized too late that the heat had scorched the rhizomes and they died from it.

I can pot it. Thanks

Just remember that a potted iris will get hotter than one planted in the ground. So you will have to be diligent in watering it and perhaps only have it in partial sun in your zone.

Thanks. I have a holding section. In earlier times I could have 20-30 plants on hold, but these days 5 is the max. I am really into workload reduction, ha

I know that with daylilies, too much summer heat, when in pots, plus fertilizer, plus water, equals rot. Been there, done that. Shade helps some, but this is TX we are talking about.

At a minimum, shade (at least AFTERNOON shade), and no fertilizer until cooler fall temps, is my recommendation. And to be honest, given the horror of TX summers, if it's going to get hot very soon, I'd consider growing indoors under lights until fall. I only say this because I've lost several new irises potting them in the summer, and we don't have the heat that you do.

Best of luck!
