Mammillaria schiedeana ssp. giselae "albiflora"
(Syn: Mammillaria shiedeana "albiflora")

Mammillaria shiedeana var. giselae "albiflora"

Description: It is a very choice and selected white flowering form of Mammillaria giselae. This plant  has smaller white flowers and many thin feathery spines, that envelop almost completely the plant body.
Stem: Spherical, clustering
Spines: No central spines ; up to 30 radials ( 4-6 mm ), feathery pale yellowish.
Flowers: Tiny (less than 1 cm) white flowers in March.
Fruit: red 

Cultivation: It needs regular water in the summer, but for the best appearance, keep water off of the spines. Do not let the soil become too dry in winter, either. It does better with a good drained soil mix since it is a rot prone species, whose roots are easily lost in pots that stay damp for any length of time. It takes a couple of years to offset, but once it starts, it can fill a 10 cm pot in just a few years. It needs full sun or light shade in summer.

Propagation: Offsets (Cuttings root quickly)
