Outstanding. I was hoping you'd post some pics of Shinya's plants. Did you two discuss any of his growing techniques in detail? I've read a few posts by him that seemed to imply he likes to allow his plants to dry out a bit.
I really hope the peltatas in cultivation start taking the same shape as his.
Can't wait to see pics of his veitchii x rajah and veitchii x macrophylla when they mature a bit more.
