Mammillaria theresae var. albiflora
 

CACTUS ART
NURSERY

Cultivation and Mail Sale
of Cacti and Succulents.


Fresh  green stem, large, white flowers. Rare!
 

NOTES: The white flowers colouration  (depigmentation) is due the absence of  the betalain pigments.  This pigments are always present in the normal M. theresae and tinge the flowers and stems of  bright magenta/pink.

Cultivation: M. theresae - like the other Mammillarias of the saboae group - is not the easiest of Mammillarias to grow and keep, this is  though it is easier than some of its relatives such as M. goldii.  But all this species require similar growing conditions, and a mineral-based potting mix is preferred. They need to be kept dry in winter.
Pot plants are quite wet-sensitively. Care must be taken with watering and needs good drainage. Water sparingly during the growing season, keep very dry in winter.  But plants grown outdoor seems to tolerate easily the winter wetness.  Usually it is recommended to overwinter this plant in a bright and warm greenhouse with at least 8-10 C , but it proved to be quite frost resistant and demonstrated to survive safely outdoor under a cover of snow at a temperatures of -15 C.
Sun Exposure: Full sun - Light shade

Propagation: Seeds
(if available), cuttings or grafting. Germination of the seed can still prove to be a challenge.
