Cold Treatment

If you had a warm fridge they'd germinate in the cool.

Robert in SF where the cool isn't here yet, but the clock is ticking for
the winter growers.

In recent exchanges, I got seeds of Ornithogalum fimbrimarginatum and
Massonia bredasdorpensis. I sowed, as I often do, in little covered
containers of promix, and left in the greenhouse. After weeks with nothing
happening I stuck both in the refrigerator for a few weeks. The other day
I removed them to a sunny windowsill, and within a day or two the
Ornithogalum seeds germinated. Pretty dramatic response, and now I just
have to hope I didn't get them all out of sync with the calendar! But I've
generally found that once seedlings get growing nicely, they figure out
when they want to go dormant.
Yes, I know I'm reinventing the wheel, but the speed of germination after
removing from the chilling amazed me so I thought I'd share.
Nothing showing yet on the Massonia.
