Gymnocalycium Specimens

I am biased about Gymnocalyciums. I like them mainly because they are relatively easy to grow and one Gymnocalycium baldianum is flowering very nicely in my collection. Gymnocalycium baldianum is one species which is very free-flowering. Gymnocalyciums generally have wide ribs so they are easy to clean if there is a bug attack. It is also quite easy to raise from seed, as seedlings are usually strong and vigorous.

My initial experience with Gymnocalyciums involve mainly mutant Gymnocalycium mihanovichii plants. I've never got around to keeping one alive for very long - they seem to be more susceptible to mites than normal Gymnocalyciums.

Still, given rich well-drained soil and suitable conditions, Gymnocalyciums grow pretty quickly.


At left is a Gymnocalycium horstii. It has very flat and wide ribs and a light green colour. I have not identified the other one. There are a number of possibilities, and as I am only familiar with a few common ones, I think I'll pass on its identity first.

The picture at left is a Gymnocalycium denudatum. It was given to me by a generous Malaysian who works in the US.

The picture shows the plant with two seed pods. This species is self-fertile. Seedlings from the collected seeds can be seen in Miscellaneous Seeds Page 3.


At left is a photo of three Gymnocalycium horstii offsets. These came from the plant shown earlier. At right are three Gymnocalycium damsii offsets. The parent plant seem to have a damaged growing point.

Gymnocalycium horstii showing offsets forming from the areoles. It probably had too much nitrogen fertilizer to gorge on. The next picture is an offset with two heads.

At right are G. horstii and G. baldianum offsets. Most of the plants I have of these two species have been grown, or propagated, from offsets.

Unfortunately, Malaysian nurseries seem to be unaware of the free-flowering characteristic of G. baldianum. Only one or two might be found in stock, most likely because it is rather less showy without flowers.

More information and photos of my collection of Gymnocalyciums can be found in the following pages:
