Hi,
I'm distracting myself from messing with my current trees by planning future acquisitions. I like the idea of sticking a bunch of cheap trees in the ground now/soonish, for potential material in a couple years or so.
One thing that I would like down the road would be to have some trees that I can use to experiment with root-over-rock styles (rock collecting is another hobby of mine, and I've definitely gotten the suiseki bug so I'd like to bring that full circle).
I know that Ficus sp. takes well to root-over-rock, but my indoor grow-space is limited so I'd like to get something that I can keep outdoors year-round, especially during the first few ugly years.
So, what should I be thinking of adding to my (probably in-ground) bonsai nursery this fall/next spring? Bonus points if it's native and/or invasive to the area around the Twin Cities, Minnesota (for yamadori potential) or easy/cheap to find in standard MN nurseries.
