4″ x 5″ wide, (seed propagated). Many years of growing this miniature gem in my Santa Fe cacti gardens convinced me of its desirability. However, it was only recently that I was finally able to secure seed of this rare, very cold hardy form of the species. Bella's thin, stiff leaves are edged with white stripes and adorned with curling white threads giving the small rosettes an appealing tidy appearance. A wonderful companion plant for Echinocereus and Escobaria cacti species. Zones 5-10. 3" deep standard pot size.
