germinating Yellow Buckeye (A. flava)
I snapped a pic, but it was too dark to be worth posting.
At the Maryland Zoo in Baltimore a few days ago, I saw several fairly good-sized Aesculus of some sort. I always assumed they were Yellow Buckeye, just based on their size, and the fact that they still have foliage that doesn't look like it was torched with gasoline this late in the year. They were just taking on a bit of fall color, kind of a yellow-orange, and the nuts were in smooth husks and quite large, bigger than A. glabra or A. hippocastanum. I grabbed a couple for the kids to plant to see if they can grow them. With the smooth husks I'm pretty sure it was A. flava I was looking at.
Anyone know the stratification requirements? My thought was just stick them outdoors either in a bag of moist medium, in pots, or right in the ground, but I don't want them eaten by squirrels. If I stuck them in the fridge, how long should they stay? Can I just keep them till spring then plant them? Or would they grow too much even in the cold after a while?
As a side note, zoos are great places to see plants that aren't quite as common...
