While the flowers aren’t impressive and aren’t even open during the day, they’re incredibly, incredibly fragrant and smell great.
It’ll overwinter inside this year, and I’ll probably try it in the ground next year. We’re right near the edge of where you can grow them, but I’ve got a nice, protected spot that should work. If it doesn’t, well, it’s only a loss of $1.50. I’m planning on taking cuttings, though, so it should survive no matter what.
Fortunately, they seem to grow pretty fast: it looks like this guy was a cutting (actually 2), and it’s already been pruned back several times.
