Q.Wilted Hydrangea Following Heavy Rain
My potted hydrangea was doing very well. It’s in a large pot, outdoors, afternoon sun, Southern California. We had an unusual heavy rain and I notice the next day the pot had not drained. I poured off the excess, even leaving it on it’s side for a while. However, it looks very sad. I do see some fresh sprouts on the inner stems. Is there any hope? Should I move it to a full sun location? Thanks in advance for your suggestions.

No, most Hydrangeas cannot tolerate full sun. They need a good bit of shade to keep it happy.
Unfortunately, this is the plight of using a container that doesn't have adequate drainage. It is best to have a container with holes that allow all extra water out, freely. Potting into a pot with adequate drainage holes, and letting it dry out some will be the next step.
A fungicide can help prevent damage from the root suffocation:
