NURSERY

Cultivation and Mail Sale
of Cacti and Succulents.


Gymnocalicium mihanovichii (var. filadelfiense)
This plant’s most unique characteristic is its colourful body ( greyish-green with white and red highlights)
 

Description: The plant is considered to be a miniature cactus. It only grows to be 4 cm high and has a 5-6cm diameter
Flowers of this species have a silky appearance and  range from white, greenish/tan to pink.

Gymnocalycium friedrichii  and G. stenopleurum are sometimes combined with G. mihanovichii, and sometimes kept as separate species. The main distinctions of G. friedrichii  and G. stenopleurum from G. mihanovichii are:

  • G. friedrichii has prevalently purplish pink, wide open flowers and well-pronounced polymorphism of spines. Besides it has tall slender ribs and roller-shaped prominent thickening around areoles.

  • G. mihanovichii has wider, lower ribs, in juvenile plants divided into separate chins, in maturity every rib have flat surface and a pleat above each areole. But the essential thing is its pale or brownish-yellow, not fully opening flower.

  • G.stenopleurum Ha white, fully opening flowers.

But many intermediate forms are also known and nowadays it is suggested that all should be combined into only one variable species.

Furthermore a number of readily distinguished multicoloured and variegated cultivars (cv. NISHIKI) only partially de-coloured) are now available. Some of this plants can be grown on their own roots and are very beautiful.
