Mammillaria nejapensis
Originally from From Oaxaca Mexico, this species forms globular stems with silvery white spines up to 5 cm in length, and dense wool and bristles at the areoles. Each single stem begins to divide dichotomously to form two stems, and will slowly form large clusters.
Description: Mammillaria karwinskiana subs. nejapensis (Mammillaria nejapensis) is very variable, especially for the length of the spines
Flowers: Diurnal, funnel-form, 18 mm long, 10 mm in diameter, pale cream with red-brown to scarlet midstripe on each petal. Blooms adorn the crown of the plant, usually in a ring, in the growth of the previous year.
Blooming seson: Spring to summer.
has medium yellow flowers with purpleish mid-veins
Notes: This is one of the Mammillaria commonly called "Owl Eye Cactus",
Cultivation and Propagation: It is easy to cultivate and make interesting specimens for any collection, and over time (in 12-15 years) it will form enormous colonies up to 50 cm or more in diameter. Provide a well-drained soil mix. Water well and then allow to dry thoroughly before watering again during the growing season. It doesn't like much, if any, winter water, but can survive short exposures to freezing temperatures (-4° C.) if properly hardened off and kept dry.
