I've got so many but this one is my favorite. Its mother is 'Seiryu'. The largest leaves are the size of a US Quarter.
Acer x palmatum 'Seiryu' (seed collected from a cultivars garden)
Oooohh! I want, I want!!
Grow him a little bigger and then clone for the rest of us! :)
I'll be tough at work ;-)
I could donate the pot and some compost!? Besides, you'll need people to test out growing your new tree in other parts of the country, right? You could name it Acer palmatum 'daxaswawa' :-)
