I was outside planting my brugs and I heard this weird noise, it was a maple tree dropping it's seeds in the wind. Hundreds of helicopters came spinning down.
I don't know what kind of maple they are, probably green maple, but these are super fresh seeds, probably with 100% germination just by sticking the heads on the seed into moist soil.

And if you run out, I have plenty more I could send too! Boy are they viable... from the garden, yard, gutters, etc!! ~ Suzi :)
