I'm trying to root a cutting in water. I got the idea online, and although it was stated that the method is not always successful, I think it's working. The picture showed a cutting with a blossom on it that was making roots in some water, so I tried a cutting from a blue hydrangea that I love. It is now showing signs of hazy 'hairy' things on the stem part that is in the water. I plan to try ground layering with another stem in fall.
Previously I also had success with placing a cutting in soil located in a bright spot without full sun, and that worked too. Neighbours across the street have a pinky red one that I think I might try next-they offered cuttings of anything they had a while ago and I think I'll take them up on it now.
