I got a pod of this in May 1999, from a neighbor in Melaka who is a collector. The seeds were from a 3" plant which had white flowers. The seeds were sown on 29 May 1999. The seeds of this species were small (less than 0.5mm in diameter) and brownish in colour. This plant may also be a Gymnocalycium mihanovichii var. albiflorus. Not really sure...
There were 6 seedlings after a week, so germination must've taken at least 5 days. After 2 weeks, there were 26 of them, increasing to 39 after 3 weeks. One or two more stragglers popped up a little later.
A total of 41 seeds germinated, out of which 39 transplanted were transplanted after 5 months. 30 plants were still alive as of Dec 1999. If the growth is a bit slow in the beginning, perhaps it's because of my closed container, twice a week care system.
|July 1999: Seedlings at 5 weeks old||Oct 1999: Just transplanted at 5 months|
|Jan 2000: Seedlings at 8 months, pot 1.||Jan 2000: Seedlings at 8 months, pot 2.|
At this point, there was algae on the surface of the soil, but luckily the seedlings were vigorous and none were lost.
|April 2000: Seedlings at 11 months, pot 1.||April 2000: Seedlings at 11 months, pot 2.|
|April 2000: Cleaning seedlings (mealy bug problem)||-|
The colour of the plants is light because the seedlings were grown under cover (translucent plastic) on a windowsill. I would conclude that Gymnocalycium damsii is quite easy to grow from seed.
As of April 2000, all 22 of the transplanted ones were left. Eventually, I moved some elsewhere and some to aquaculture in an effort to speed up their growth.
|June 2001: Seedlings||June 2001: Another pot of seedlings|
Here are a couple of pictures of the plants in June 2001. These were grown in soil. The adult features of the species is evident in the pictures, so I guess they should not really be called seedlings now, or juvenile plants, but young Gymnocalycium damsii.
The picture on the right shows four specimens, from the same batch but grown in different conditions. I do not recall what turned them into a shade of dark green, but at least three of them recovered.
