Garden-type peonies can be seen far and wide in zones 3 to 8, and less in zones 9 through 11 and in the lower end of the spectrum. If you wish to grow them and live outside the recommended zones then it’s best to choose the early blooming variety that will flower before the summer heat rises.

Peonies can grow in states where they get enough ‘winter chill’, or a period of cold that they need to start producing buds. Texas, New Mexico, Arizona and California are just several examples where peonies can thrive and wow viewers with its bold, color-changing foliage and exquisite and fragrant flowers.

The first thing you’ll want to do is to pick a heat tolerant peony and determine the best conditions for growing it. Keep in mind however, that peonies in warmer zones tend to have shorter-lived and smaller flowers compared to those in the recommended zones.

In Hawaii, you can grow peonies in a location that gets full morning sun and partial shade in the afternoon. They won’t survive being exposed to too much heat and humidity and will likely get stressed out. As for medium, peonies grow best in well-draining soil that’s rich and fertile.

Plant your peonies just several inches below the ground level and leave the soil as is. Mulch won’t help in this case since it will need wind and low temperature to properly set and become established. Furthermore, it’s best not to disturb them and not move them from one location to another.

Give your peony regular watering so the soil stays consistently cool and moist during the growing season. Also, remember to water deeply and until the water starts draining out through the designated hole.
