For those here understanding climates in Australia: When should I start watering
Calostemma purpureum? They grow for me but haven't bloomed. I have been keeping them
inside my house in their containers since they died down last spring. A lot of
discussion in our archives suggests they need good soakings at the end of summer when it
is still hot in order to flower. In the past I haven't watered them until it cooled down
in November, but then recently I read about late summer watering.

We still have daytime temperatures around 110F / 43C and will be above 100F / 38C during
the day for at least the next two months, through mid or late October. Nights are in the
range 85-90F / 30-32C though they will start cooling in a month or so. We may still get
summer monsoon rain through mid September.
