Sugar Blues is a gorgeous plant with a heavenly fragrance. In my zone, it is also a rebloomer. There has been no one that has visited my house when it blooms that has not made comments about it. I can highly recommend it!

Sugar Blues is a good grower for me and has a heavenly fragrance. It hasn't rebloomed yet, but almost nothing reblooms in the mountains of New Mexico.
October 10, 2008 -- Sugar Blues rebloomed for me. It is very welcome right now just a few days before our first freeze.
