I've currently got aniseed myrtle, native ginger, fingerlimes and round limes growing indoors, mainly due to the frostiness of my garden in the Adelaide Hills.
All are in high-light, high daytime temps but relatively low ambient humidity. Humidity/microclimate is improved, I guess, but having them in those water-well pots...
All are growing well, except one fingerlime but I don't think that's related to its indoors-ness. At risk of meandering off topic yet again, ddoes anyone know why my fingerlime's skeletonised, for the want of a better word? All leaves now go and the little branch tips have died back... The other one had it to a lesser degree but has gone off like a rocket of late. Though it might be a soil acidity thing, but iron sulphate hasn't seemd to have helped any.
Anyway, I hope this has been of use Nessie. Other species that might be worthwhile trying to grow inside are davidsons plums (cos they seem to like more shady spots) and similar rainforest plants.
