Get the 'Usugumo' it is really hard to graft and as a result very rarely available. Can't do better than getting one of these from Matt and Tim, and the other stuff will be available later. It may be that mine struggle a bit because of the really low pH, though 'Hoshi yadori' does fine right next to one of the 'Usugumo'. I really want to get 'Hot Blonde' into the garden, it looks like a real winner. Another yellow to consider is the excellent A. buergerianum 'Michael Steinhardt'. I got one of these from Matt a couple of years ago, it's very pretty although doesn't have it's feet well under it.
That's looking fantastic D. I'm just counting the days until it comes over here and when it does, I will be the first in the queue to buy one.
Alex blog have lovely pics of his trees. I use to look at it all the time until I lost the link. Now I have it again. Thanks Alex @alex66 Do you prefer it in full?
One thing I'm particularly struck by with 'Usugumo' is how different the plants are. Our 3 are all from Esveld, and presumably from the same mother plant. But look at them today: Plant 1, morning sun only, very pink: Plant 2, afternoon sun, very yellow: Plant 3, pretty shady but colder and windier, pink but only just getting started:
