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.
A close-up of the flower. This plant in my collection was grown from seed sown in 1980.
Here is a picture of the
same species which I saw in flower in Mexico in 1998.
