I LOVE THEM.
Who loves them/has them?
They just GIVE GIVE GIVE.
This summer we had the worst hail/mini tornado storm I've ever seen in my area. All of our plants (including 15+ geraniums) were stripped completely of leaves. We lost about $200 worth of plants, and were devastated to see some geraniums we've had for generations (one is ~40yo) almost destroyed.
A week later, all of them were shucking out the leaves like nobody's business.
By now, all of them are back to full size specimens.
They live on a baker's rack in my room during the winter, and should all be in full bloom next month.

I'll post pictures.
