Some time back, on the 22 April, I wrote about the weedy orchid which grows in the Adelaide hills. I included a picture of this weed which had been kept in a bag for over a week and the little shoots looked fairly healthy. I thought that was quite impressive that it had managed to live without water or sunlight, and now…
It is nearly a month and a half since that weedy orchid was placed in a bag, and it is still alive! Wow! No water, no sunlight, just living on the energy that was stored in its tiny bulbs. That is amazing.
When I was first told that if one of these orchids was uprooted while in flower will continue to produce seeds, I was a bit sceptical. Surely no plant would be able to continue to grow when placed in a bag, but now I’ve changed my mind.
My understanding is that Disa bractreata is a desert plant from South Africa, and this would explain why it is so tough and hardy. It does not require much before it takes off and is all through a site. Interestingly I can’t recall seeing this weed in moist areas, but I could be wrong. I’ll be looking out for it to see if that is so.
In the meantime, this Disa bractreata can continue growing in its little plastic bag. I wonder how much energy is in those bulbs, and when will it start looking thirsty. This orchid is making me curious: I want to find out how tough it is, and what does it take to kill it, though this would be the only orchid I’d want to destroy. It is a pity that many of our native orchids are not very that tough, or maybe they are tougher than we think!
