Astrophytum asterias forma variegata
This is a nursery produced cultivar.
Astrophytum asterias forma variegata presents sectors, patches or stripes with two or more different colours (that may be distinct shades of green). Stems is normally green, and tissues lacking chlorophyll are usually white, pale yellow coloured or reddish, contrasting beautifully with the normal green tissue.
Variegated Astrophytum are relatively easy to grow. They need half shade or under-filtered sun: they cannot tolerate protracted exposure to direct sun light, especially during summer. Put them in mineral, well-draining soil with little organic matter. Water sparingly from March till October. These plants are not frost tollerant, so keep them perfectly dry in winter.
Propagation can easily be done by seeds.
The variegation on these Astropytum is due to a lack of clorophyll, that makes other pigments visible.
