Telope Speciosissima are notoriously difficult to grow. They are local to may area, and I have failed at 2 attempts. The hybrids however (and there are many of these) are a lot easier to grow. Some of them look very much like the Speciosissima, so you might want to grow one of these also in case the real thing carks it.

I'm in west Tweed Heads and the only one I've managed to grow is T Speciosissima x mangaensis 'Corroboree'. It's been in for about 4 years and is thriving on a well drained sloping site on acidic, red volcanic soil, where each year it flowers prolifically. After flowering I cut it back by a third to a half and it again powers away. As for others though, including the white one, all have failed time and time again. Try corroboree, it's a toughy and a good flowerer.
