I decided to try growing Angelonia from seed this year. Out of 12 seeds planted 2 sprouted and look very healthy. I won't try that again as the seed (20) was close to $5.00. I live in zone 4b so I'm not sure if I could over-winter them in the garage. I do have a basement that stays about 50 degrees but there are no windows in it. Would they have a chance of making it through the winter in it?
