Visited Rehoboth Beach, Delaware over the weekend and was pleased to see some big clumps of M. basjoo planted around a guest house:

Looking more closely I was surprised to find that several of them were blooming:

Around the back, there was an even bigger clump, although oddly enough I didn't see any flowers on these:

This guest house also had several hardy palms planted around it. Lots more photos, from this location and another in Rehoboth, in my photo album (see link).
