thanks Ed - i sure have a lot of "unintended" aussie bonsais ....! For instance my Citrus australasica's...!
i reckon both brachychiton rupestris (bottle tree) and b. acerifolius (illawarra flame tree) would make awesome bonsais too.
u know, regarding the baobab post on SAB Ed, i think B. rupestris is a kind of "everyman's baobab", easy to grow, tolerant of cool wet conditions, fast-ish growing, and quick to develop the swollen trunk.
also i spose A. gregorii COULD be bonsai'd.... oh man... i shudder to think of the effort involved! For one thing it would need to be heated all year i reckon, even in the dry winter.
and i think the ficus spp mentioned, esp. the port jackson, are very much prized for their bonsai-ability, even overseas. Can't beat those aerial roots
oh yeah and sometimes at the markets i see very advanced, fruiting bonsais of exotics like peach trees, apple trees etc.... i reckon a native like Solanum aviculare would be PERFECT as a bonsai, with its smallish, ever-colour-changing fruit. WOuld look gorgeous.
