This was last year actually, so far this year both ‘Apple Blossoms’ are blooming, a deep red is definitely going to, and we will see about the rest. We tried marking them last year, but the markers are now illegible!
They spend the summer outside, (happy and green in the shade), a few months in the basement (dark and dry), and then spring into life in the winter with the judicious application of radiators and water. We even have babies from seed. Have no idea how that will work. They do pretty well, the red one in the photo above was a surprise last year. We had kept him for years, but he hadn’t bloomed in quite some time, and then last year he finally decided to once again. The ones you buy at the store are awfully confused for several years.
