(A. myriostigma x A. ornatum)

Cultivation and Mail Sale
of Cacti and Succulents.


Astrophytum  MY-OR is a beautiful  hybrid with (usually) 8 spineless short spined sharp ribs.

Many very different Astrophytum hybrids have been developed involving A. myriostigma & A. ornatum and are now in cultivation.

The superb feature of some of this hybrids is due to the intersection between the traits of the ancestors and make  them very desirable. Ribs are sharp usually eight (like in A. ornatum)  and are spineless (or whit very short spines) clearly indicating the relationship with A. myriostigma.
This hybrid are strong growing. The flower are also very beautiful.

Five ribbed plants with short spines are not infrequent.

A nice form with curved spines

This quite variable plant has been widely grown for years and is now available in several cultivated variety and several breeds do exist. Now it is represented in many collections and readily available.

Cultivation: Although regarded as a choice and difficult plant in cultivation it is relatively easy to grow. It is sometime seen as a grafted plant but grows very well on its own roots too. Use mineral well permeable substratum with little organic matter (peat, humus). The Astrophytum myriostigma grows much faster with a low nitrogen content fertilizer in spring and summer. Water sparingly from March till October, the thin, fibrous roots suffer if there is humidity, therefore the plant should be watered only when the surrounding terrain is dry. Keep dry as soon as the temperature starts dropping in October and keep it perfectly dry in winter at temperatures from 5 to 15 degrees centigrade. (but it is Hardy to -7C for short periods) Although it is one of the easier Astrophytum to grow, they tend to rot at that time of the year, if kept wet. In the rest period no high atmospheric humidity!! Sun Exposure: Light shade to full sun, its colour tends to richer and darker when grown in light shade.

Propagation: Almost exclusively by seed. Plants are sometimes grafted onto column-shaped cacti. Cutting scions from a flourishing plant is almost a crime because the scions do not root easily.
