Oh No! Hydrangeas in Garage Sprouting!
I brought some of my baby hydrangeas into the unheated garage in the fall. It included two small Masjas and some fall cuttings of a local lacecap and mophead (don't know what kind). I didn't bring them in until late December because it was so warm. I've watered them twice since they were brought in. The other day when I went to water them, I noticed that the Masjas both had sprouts growing out of the soil (one has two 6" stalks and the other has about 7 1" or 2" ones ) and the lacecap cuttings had buds opening up.
It's been warm all winter and though the garage is unheated it's somewhat warmer than the outside. It almost never goes below freezing. It's also pretty dark.
It's February in Massachusetts! I wasn't going to bring the plants out til maybe May. I guess I should keep them inside until after the spring freezes, but now I have visions of giant white hydrangeas taking over the garage! The sprouts are actually light green - not sure how they're producing chlorophyll in the mostly dark.
