Jen,
They don't last for more than a season or two in z9 so I don't think you'll have any luck in z10. Sorry. I miss them too.

I just read a post from a gardener in Alabama who said that peonies don't do well there because of the heat. ALA is zone 7-8. I love peonies as well, but in z10 I think that we can just forget about them.
sorry,
Avalon
PS - some large flowering triple hibiscus sorta look like peonies, and we can grow those here, plus they flower year round.

One of the big ruffly camellias may work too.

Thanks, guys. I love all the tropical plants that thrive in SoFl, but I am a greedy gardener. I want to grow all the things I loved to grow up North too! I guess I should just be happy with my hibiscus and bouganvilla. Thanks for all the responses!

Wayside sells one they claim will work in zone 9 but I called the horticulturist and he said don't even try. I did read somewhere about some trick about packing them in ice or something like that, ANybody know?

They just can't take the heat. They will wilt and falter if they even get a touch of our direct sun.

I had trouble growing peonies in the Atlanta area when I lived up there--summers were too warm and wet. Not enough winter up there either!

Please, make the adjustment to the area in which you live!

Just looking at the Wayside catalog. They have one peoney they say can go in zone 9 and a couple of tree peonies.

Hi
If you really, really want to grow them you can "reverse cycle" Get ones that have been pre chilled ,plant out in Oct. grow until May or when they decline. Dig them up clean them VERY well put them in cloth bags in the refrigerator until Oct, and start over . If we have a particularly cool winter you will get some flowers if not you'll get some spindly growth. This works with most of the temperate bulbs but sure is a lot of work .lol gary

Couldn't a person make a "sack" out of chicken wire...put the bulbs and peonies into it...plant with all the needed drainage, mulch, ect. in pots...then when it's time to remove them...just pull of the chicken wire with the bulbs in it...put in paper bag and refrigerate or freeze?

Okay, so I know this is a very old post but I thought some of you may be interested in some tree peonies I found. They are proven to zone 9b. I am further down than that in south Florida so I can't try them. But... it maybe worth a shot for someone else. I also read that some people use ice water when watering their tree peonies in Florida and Texas. They also dump a bag of ice on the dormant plants. Some say that they have had great success but I am on the fence. Here is the link https://www.treepeony.com/collections/tree-peonies and https://www.treepeony.com/collections/itoh-intersectional-peonies

Try contacting your local University of Florida agricultural extension Master Gardener. The one in my zone 9B area suggested a Chinese tree peony variety, Snow Lotus. They do well in hot,dry Dallas, so-check about Florida.There's a Connecticut grower, Cricket Hill Garden, that has it for sale. Again,try the Master Gardener. Good luck.

I have tried to grow them for about 4-5 years and no luck.

Sadly, you can walk into any local HD or Lowes right now and in the bag bulb bins....full of subpar peony tubers, ranunculus, freesias, ect. Anyone just moving down to FL would not know any better and fall into the big box store growing zones be damned sales tactics.
