Gymnocalycium baldianum in Aquaculture

This is a series of pictures showing the growth of my prime Gymnocalycium specimen. I've got lots and lots of pictures of this plant, so allow me to give you a pictoral history. This plant probably started as an offset, since the only time I bought Gymnocalycium baldianum seeds was late 1999, from Mesa Garden.

Aug 2002: On checking old photos, I found the parent of this specimen. It is a mature Gymnocalycium baldianum bought in Bangsar, KL while in bloom. The parent plant was killed by spider mites and scale insects, but not before producing a number of offsets. This is one of the offsets from that plant.

Oct 2002: If you want to look at a sorry-looking picture of the parent plant (Warning: it looks awful), it is probably the first picture in Mites Problems Page.

Jun 1999 Jan 2000

The first picture is one of the earliest I have of the specimen. I took the picture because a piece of it had been bitten off, probably by a bird. By January 2000, the scar was almost invisible, due to over 1" of new growth. Normal spines appeared with new growth. This specimen had the advantage of being one of my early aquaculture specimens at a time when my grasp of aquaculture was starting to pay dividends.


Jul 2000 Dec 2000

By July 2000, the plant has grown to over 3" in diameter (the cup is 2" in diameter). The ribs are very fat and the distinctive Gymnocalycium 'chin' is clearly visible. The scar is completely obscured by new growth now. Note that the specimen has almost perfect skin, something that would never have been possible if it were grown in soil in my collection.

March 2001: The plant started producing its first bud in mid-March, and the flower opened on the last day of March 2001. C&S collectors in the tropics don't get this very often because the weather is not very suitable for inducing bud formation in most genera and species. Many Mammillarias are willing to flower, sure, but one does not get many species bearing large, brightly-coloured flowers. The following page has a set of pictures of the Gymnocalycium baldianum's first flower:
