Description
A. myriostigma cv Onzuka "tricostatum" with only three ribs - is one of the most sought after cacti, that have fabulous markings much like the ‘kabuto’ asterias. There is a variety of variations in ribs shape and in stems markings.This cultivar tends to be unstable, and some of the three ribbed specimens develop additional ribs as they age. Old and big plants which maintain the typical three ribbed shape are very prized. If you are so inclined you can pay large sums of money for some of the best Japanese forms.
Flowers
