Here I go with the tropical trees' list...
Well, I live in a tropical country, but I don't find Azaleas so exigent... well, maybe, because I use 100% organic soil for them (don't ask me why...) but, they do fine... well, if you allow me to add a tropical tree that is hard and easy at the same time... here I go
The bahuina's species... they grow like weed... they grow so fast that I had troubles of root bound in about 3 months... well, but they are forgiving trees... they will grow from nothing, but the other con, is that they will hardly make it in a different style than cascade...
If I should add a slow grower, well, CEIBA PENTANDRA, and this is a headache tree... it won't develop small leaves, so well, it won't make it different than blooming style. But it can live for centuries... (eventhough I can't)
Well, two nice trees, I'm trying to get from seeds are Tecoma stants and Tabebuia rosea... Let's see if they are good for that... well, they are easy to water, but hard to fertilize
I had troubles with 2 Tecoma stants... because of the fertilizer...
Then, how about Jacaranda
? Jules told me they won't make good bonsai...
well, bye
