What is the possibility of S. guaranitica crossing with a microphylla? I ask this b/c one of the sports from my Black and Blue last year had red flowers and bloomed late summer until a hard freeze. At the time I collected the seed from my B&B I also had Wild Watermelon growing in close proximity. The leaves have the 'odor' of my B&B but they are shaped more like Wild Watermelon. They are also have a soft dwney feel.
