Astrophytum asterias cv. HAKUUN forma prolifera
The branching habit of this cultivar is an uncommon characteristic
rarely seen in this species.
Furthermore this cultivar shows the unmistakable cloud-like white
patches on the plant's body typical of the well known Japanese "hakuun".
This is one of
the less known and strange Japanese cultivars. It is seldom seen

but grows very well on its own roots too. Use mineral,
well permeable substratum with little organic matter (peat, humus).
Water sparingly from March

perfectly dry in winter,
at temperatures from 5 to 15 degrees centigrade.

In the rest period no high atmospheric humidity!!
Sun Exposure: Light shade to full sun.
