Well, its fertile. I wasnt sure, with a mixed ploidy type like this. [(Yellow Brick Road x Winter Sunset) x Sunrise Vigorosa] began germinating in February, and is continuing to do so, laying rest to questions about fertility. I have never seen it set hips, however.

As for the plant itself, it is fairly nice. I have never seen any disease. Vigor is moderate. Size and rebloom are average. The yellow is yellow enough to be nice. The only drawback is that it can get chloric without enough minerals in the soil. The foliage will become lime-colored without that.
