This winter I wanted to find a new way to make some serious money. So I went and got some crape myrtle seeds from my brothers tree. I got like thousands of seeds. I sprouted them in a paper towel, potted them up like I do my boxwoods and they sprouted out of the dirt. How long will it take them to get to be 4' tall? And how tall will they be on average after 1 full year?
