Thunia Bensoniae

[s1214215]

Hi

I just got three plants of this species from a market outside Bangkok. I have pollinated it and will try stem culture in flask.

I hear it likes it a little cooler than Thunia Marshalliana, though grows much the same. Any comments on culture are welcome.

Really pretty.
I like thunias and used to have several plants.
It likes remarkable day-night temperature difference which is important for them to bloom.
Thunia can be grown like some terrestrial orchids, such as Arundina or Neobenthamia. The only diffenence is that thunia drops all its leaves in late autumn and then enter its winter rest phase. During the rest, it should be keep dry to aviod rotting.

Thanks Pheli

I have seen T. Marshalliana growing in full sun in the mountians of Burma. So, seasonal light and a cold set certainly are needed. I have no idea why they bring these plants to Bangkok. I have mine in the cool wardian case at 23c. I really want to propagate this species as I have never seen it in Australia and want to take it back.

Though thunias are from highlands, they do grow well in subtropical or even temperate areas.
As I mentioned, they like low night temperature to bloom well. So they seem to bloom well in temperate areas rather than subtropical or even tropical lowlands.

Hi Pheli

I agree, Thunia can grow in the sub-tropics. I have seen them doing a lot better in temperate ereas with a cooler winter and have seen them not doing that well in the tropical lowlands. Still, if it can be done, why not.

My experience has been with T. Alba and T. Marshalliana and not T Bensoniae. I was wondering if there was much difference or is this species the same.

Thanks for the advice.

Brett.
