And now I've gone and ordered $40 worth of maple seeds. It's a variety; 'Crimson King', sugar maple, and four kinds of Japanese maples. I've had good luck with germinating maples before but I lost the seedlings when the greenhouse collapsed one winter. The place I used to buy tree seeds from seems to be out of business even though their website is still up, so I'm trying an ebay seller who has a 99.3% positive rating. Soon my house will be full of flats of germinating seeds of all kinds- all with cats laying on them.
