This is the Confederate rose. Actually, this one is a sport, hence the two tone appearance.
I have them that bloom pink, then turn colors to finish as a crimson bloom. And I have them that bloom white, and turn to crimson. Both are show-stoppers when they are in full bloom.
The bloom is enormous, as big as a man's hand in most cases.
This one is from a wayward seed, so it isn't really sure which way it is going to bloom. It isn't all white, nor all pink. Not very big, but not a single as many sports are. (The singles remind me of magnolias.)
I like it anyway.
This plant is incredibly easy to propagate. Just cut it and stick it; don't let it dry out. It will grow.
