I purchased a blooming ranunculus plant at a big box store. It had no info with it and all I could find online was info concerning the tubers. Should I plant it in the ground in the sun or would it do better in a container? Will it survive our hot, humid summer? It's a beautiful healthy-looking plant.
I agree, Ranunculus are beautiful!
You can plant it directly into the ground after all chance of frost, or leave in pots.
Bulbs will not winter over and will need to be dug back up in the fall.
Here is a few articles about the care of your plant and the bulbs.
