Well, I've taken the leap into Australian Terrestrial Orchids ! I'm starting with tubers of 4 different species so I figured I'd start this thread right at the beginning........ with some photos of the tubers !

I'll post updates here as they come.

Caladenia flava


Diuris aff. corymbosa


Elythranthera emarginata


Thelymitra crinita

Very interesting where and how the various plants store the reserves for next season's growth.

I agree, all species seem to have a different yet similar strategy. Both Diuris species look nearly identical. I'm curious what different species in the other genera might look like.

Here's something to look forward to in the future Johnny.

I've been growing a few Pterostylis for a few years. For me they are hardy.

Pterostylis curta

Very cool! I hope they do well for you, I've wanted to try some of these genera but am holding out until I have a more controlled growing environment.

Nice Pterostylis, Fred! coccinea is especially pretty, not one I'd seen before.

Gorgeous Pterostylis flowers! Cthulhu, I can't wait to see how these grow. When will they start to wake up? Are they summer growers?

They're just starting to wake up but they're fresh imports. They're still tuned in to Southern Hemisphere winters. They'll be acclimated in the same way I do my tuberous Drosera. They'll have a shortened growing season followed by a shortened dormancy. With any luck, I'll see flowers next winter.

Indeed. The Caladenia flava tuber looks like a sperm cell. All it needs is to start whipping that long strand like a flagellum.

Which when you consider the fact that the Caladenia prefers the driest conditions of the four makes perfect sense. Gotta get that food put away where it won't rot!

You've started your collection with some tricky species. The C. flava and the Elythranthera in particular are notoriously difficult to grow, even by the so-called expert growers down here.

Most growers here use rather elaborate substrates so it will be interesting to see how you go.

Currently I grow around 200 species\forms.
