These bulbs grew over night! When I went away to Kansas, they had only grown about two inches, and when I came home, they looked like this:
I found out that paperwhites really like cool temperatures. I took two bulbs downstairs to my room where it is very cool, and two weeks later they both had a nice root system. The three bulbs I left upstairs had no roots. So I brought them downstairs and they spouted roots right away, but they’ll be flowering about two weeks later than the others. I can’t wait to see them in bloom!
