	Astrophtum myriostigma	CACTUS ART NURSERY Cultivation and Mail Sale of Cacti and Succulents.

Astrophytum myriostigma
Flowers: Arise from the areole at the tip of the stem on mature plant (at least 4-5 years old) they are large, funnel-shaped, yellow, 5-7 cm wide. Blooming intermittently throughout the warm months from spring to autumn.

The fruit of A. myriostigma (above) is very hairy, dehisces apically and has a greenish inner colour, it is very different from the fruit of A. coahuilense (below) which is pinkish and opens basally.

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). Water sparingly from March till October and keep perfectly dry in winter at temperatures from 5 to 15 degrees centigrade. (but it is Hardy to -7°C for short periods) In the rest period no high atmospheric humidity!! Sun Exposure: Light shade to full sun. Propagation: Almost exclusively by seed. Plants are sometimes grafted onto column-shaped cacti.
