NURSERY

Cultivation and Mail Sale
of Cacti and Succulents.


 M. glassii is a sweet little mat forming plant, that offsets heavily and forms a beautiful low white cushion. Flowers very small and pink for two months in Spring

 


Mammillaria glasii 'Dulces Nombres'
(with short yellow hooked spines)

(Field number: L 1537Locality: track from Dulces Nombres over Santa Engracia, Tamaulipas, Mexico 1800m)

 

Description:  It is a small plant that forms low clusters. Individual  stems are globose, becoming cylindrical, up to 10 cm high, but rarely exceeding 3 cm in diameter without latex.
Spines: Radial 50 - 60, hairlike, white, interlacing, 10 - 15 mm long, centrals 1, 4 - 7 mm long, erect, straight or hooked, but difficult to distinguish from radials. With few to 30 white bristles up to 25 mm long in the tubercle axil.
Flower:
Often not opening completely, light pink, up to 14 mm long, 3,5 mm in diameter. Fruit: very ornamental green, becoming pink-reddish, up to 20 mm long.

Cultivation: Of easy culture, recommended for any collection, it doesn't require any special treatment.  It readily forms clumps of many small heads. It needs as much light as possible without burning the plant, to encourage the heaviest spine formation. Growth and flowering are improved under these conditions.  Use very gritty potting mix (rot prone).  For best results, use a shallow pot,  and only use the smallest diameter pot that will accommodate the plant. Regular water in summer, dry in winter. The use of a covering gravel is a good way to preserve the whiteness of spines. Frost tolerance -6° C. Reproduction: Seeds or offsets.
