Do you live in a sweltering climate that can liquefy an ice cube in two seconds flat? Afraid that your selections of dahlia varieties might melt in your local heat?

This is the thread to discuss what varieties THRIVE in heat. Be aware that some hot climates have either dry or humid conditions, which might have influence on the varieties that do well.

Here's three links that might help, complements of the Dahlia Society of Georgia.

It would take some time to compile a complete list, but off the top of my head, these are tough ones that did well in the heat and humidity of our North Carolina summers.
Our temps are usually in the 80's -90's, so you always want to get an early start to the day here, then head inside for the afternoon....if possible.
The dahlia plants will usually wilt in the 90's, but tend to recover in the late evenings.
You would never cut them, except in the early am if you want them to last in a vase.
It is also common to get some wild storms in the summertime, so it's important to stake the dahlias. They've never made it through a summer upright, otherwise.

Mikayla Miranda. Last year when Swan Island was baking in the record heat, and many varieties were neither growing nor blooming, the whole row of Mikayla Miranda was tall and strong and full of good-looking blooms. The contrast in the field was striking.

Thanks Linda! That's good to know. I love the white with lavender edges on lots of different dahlias. The problem we have here is that they fade out in the heat, and appear to be mostly white. Then, in the Fall we get to enjoy what it's meant to be.

Annie, please edit your post above to include your state and average temp range during the growing season. Also, talk about humidity (or lack-thereof) so future readers problem solving their climate can be assisted in knowing if your list might work for them. Thumbs up

...crazy enough to grow dahlias in
I will attempt to make a list of best of the heat tolerant dahlias I tried this year.

Kentucky, zone 6b, high humidity in June /July with thunderstorms, high winds and temps in the 90's to which the garden is fully exposed; no shade and very little wind break:

Alpen Fury is a blooming Machine with strong stalks. Stems could be better, but it withstood all the weather and remained upright with virtually no support. Good tuber maker, good keeper.

Croydons Masterpiece was a short plant but bloomed and bloomed. Needs support. Not many tubers, but keeps pretty well.

Camano Sitka, very floriferous, good keeper, average tuber maker, needs support, good stems.

Hee Haugh, very floriferous, needs some support, good stems, good keeper, average tuber maker.

AC Paint, needs support, strong stems, some heat deformed blooms, not stable for color, but always blooming so would be a good choice in the worst heat for weird cut flowers, or a great garden mass planting focal point. Cooler weather makes for better bloom form. Excellent tuber maker and keeper.

Windhaven Blush, very floriferous, needs support, good stems, good tuber maker, good keeper.

All would benefit from some afternoon shade.
