Date: 1999 May 29

Thelocactus bicolor is perhaps the species of Thelocactus most often encountered in cultivation. It does not present any particular problems, and although growth is fairly slow it can be relied upon to produce its attractive flowers occsionally from each new areole through the growing season.

Here is a picture of the same species which I saw in flower in Mexico in 1998.
