Gardeners' Notes:


On May 11, 2005, Xenomorf from Valley of the Sun, AZ (Zone 9b) wrote:

The 'parkeri' subspecies grows in a tighter compact clump and the stem tips taper sharply. It has 7 to 10 very tubercled ribs and 7 to 10 radial spines per areole.
The 'arteagensis' subspecies has 14 to 18 radial spines & 5 to 8 central spines per areole.
The 'gonzalezii' subspecies dosen't form tight/compact clumps and the stems taper gradually. It has 6 to 10 ribs that are barely tubercled. It has 10 to 14 radial spines and 3 to 5 central spines per areole.
The 'mazapilensis' subspecies has 6 to 9 radial spines and 1 to 4 central spines per areole. The seed structure is different than the other 3 subspecies.
The flowers on all are deep-pink to magenta with white throats.
