Japanese Maples are the #1 for me. I find them extremely easy to grow, and I seem to torture these things left and right and they respond just nicely.
Aside from that I also like growing Satsuki's, although I must say I was a complete failure of that last year.
Shimpaku is easy for me too... at least I can keep them alive, and that is good enough for me.
Quince is another very easy one and its easy to make forests/groves with them because they sucker so much.
Pines on the other hand.. I'm trying my hand at them right now, so I dont know if I can be a success or failure at them...
