Amazing but scary

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!

    Just got some more weedy orchids and I’m going to see how much they can cope with. You can follow developments on twitter using #HowHardyIsWeedyOrchid. Share any experiences you have seen regarding this weed. I would love to hear any stories.
