Allen Lowries "Carnivorous Plants of Australia - Volume 2" is almost entirely
dedicated to these plants. He describes the dormancy requirements for most/
all species. If you can't get access to this book (it's getting hard to
find), E-mail me a list of species and I'll see if I can find their growing
requirements for you.

I'm a bit slack with my plants, and keep them on the floor of the glasshouse
and water overhead occasionally - I have lost a couple of species, but most
are going OK. Tray watering is a bit risky for some of these plants, unless
you know their natural habitat. Some grow in swampy areas, but others are
in sandy heathland which is exceptionally well-drained, so tray watering may
rot them.

At the moment, I'm waiting to catch my D. callistos in full bloom. I missed
the first two flowers but the third is due to open in the next couple of days
if the weather stays fine... Luckily a second scape has appeared, so I'm
in with a chance!
