If it needs water, it completely wilts. The first time I found it in a slump, I was ready to add it to the compost. I watered it and, to my surprise, a few hours later it pepped up. This has happened repeatedly. Today was a perfect example.
This morning

Leaves sagging over the pot and the petals completely drooping.
Tanked it up and Bob’s your uncle.

All perky, flowers standing tall and new buds on the way. Happy with just a little sunshine and water. Until the next time.
