The summer in the DC area has been rainy and hotter than usual, and I am sad to see my iris die every 4 years due to the unfavorable conditions. I have amended the clay soil with sharp sand and compost and grow iris in raised beds, but still the odd wet year takes its toll.

So, I'm looking for iris, new, older or historic, that can take the 90F plus July and August days when the rains come. Hot, humid, rainy every 4th year or so. Love rebloomers. What are your suggestions?

Thanks, iris friends!
Yes, I trade iris!

My yard is heavy clay for the most part. While our humidity is in no way comparable to your area and we tend more toward drought conditions, some months the rains are unending and humidity is consistently high (as opposed to a day here and there). Which means that I've lost a big chunk of Irises to rain rot over the years. But I do have Irises that shrug off ALL conditions, so maybe you could consider one or more of them. I posted a mix of classifications and colors, plus a middling number of them are listed as rebloomers. Thumbs up

Abbey Chant // Betsey Boo

Blaring Gale // Bonjour

Bottled Sunshine // Cat's Eye

Catwalk Queen // Constant Companion (reliable rebloom here)

Crooked Little Smile // Crystal Beauty

Crystalyn // Dracula's Shadow

Flo (reliable rebloom here) // Flower Shower

Frosted Velvet // Golden Apricot

Grand Canyon Gold // Highline Amethyst

Hollywood Lights (stalks tend to lean over here) // Intermediary

Joyce Terry (in top 5 for toughness) // Lest We Forget (I've had blooms on this one going into December)

Quaker Lady (Leads the top 5--she is one tough cookie) // Sharp Dressed Man

Snow Maiden (only bloomed once in six years--think it needs more cold than we get) // Stairway to Heaven

Talisman // Terra Rosa (in top 5)

I.germanica (rounds out the top 5) // I.orientalis
It’s okay to not know all the answers.

Look like good suggestions to me, even though we are not horribly humid in New England. Check with Winterberry Iris Garden in VA. They would have more experience with your climate than some of the western gardens.
