Escobaria vivipara RP113 FT Union New Mexico
 

Description: Escobaria vivipara is a small solitary or clumping cactus.  Some varieties form colonies of over 200 stems. This species is the most widespread, abundant and variable member of the genus.  It is densely covered in a mat of star-shaped arrays of spines.
Stems: Usually more than 1/2 above ground (sometimes deep-seated and flat-topped in winter, in cold climates and/or in immaturity), spheric, ovoid, obovoid, or cylindric with age, 2.5-75 3-11 cm tall;
Tubercles: Grooved, 8-25 3-8 mm, stiff or flaccid; areolar glands absent.
Roots:   diffuse, less than 1/4 of stem diameter.
Spines: 11-55 per areole; either bright white, ashy white, pale tan, pale pinkish gray, or reddish brown (rarely stramineous), tips dark bright pinkish brown, reddish brown, dark brown, orange-brown, or pinkish orange, purplish gray, pinkish gray, brownish red, sepia dark purplish brown, or stramineous, opaque or vitreous, fading, then blackening with age (dark tips rarely absent).
Radial spines: 10-40 per areole, weakly appressed or tightly appressed, pectinately arranged in subadults of some populations, 7-22 mm long.  Subcentral spines are sometimes present.
Central spines: Straight; outer central spines 3-14 per areole; appressed or strongly projecting, in "birds-foot" arrangement or radiating like spokes, longest spines 9-25 mm.
Flowers: Subapical, 20-65(-90?) mm long; outer tepals conspicuously fringed; pale rose-pink to reddish pink or magenta (or rarely yellow or green) , sometimes with darker midstripes, sometimes shading to white or pale green,
Fruits: Green, exposed portions slowly turning dull brownish red, ovoid to obovoid, 12-28 7-20 mm, juicy; floral remnant persistent.
Seeds: bright reddish brown, comma-shaped or nearly obovoid, (1-)1.3-2.4(-3) mm.
Flowering season: Spring-late summer; fruiting 2-5 months after flowering.

Escobaria vivipara
SB383 Howard County, Texas, USA

Notes: The showy flowers of Escobaria vivipara are virtually identical to those of Coryphantha macromeris and Mammillaria wrightii; in the absence of vegetative material, flowers may be unidentifiable.  Some unrelated species, such as Coryphantha echinus, vegetatively resemble.

 

Cultivation: It comes from an area of summer rainfall.  Keep drier in winter (but for outdoor cultivation it is very resistant to wet conditions, too). It needs good drainage. Very cold resistant, but the frost resistance varies a lot from clone to clone. It can easily be grown outdoors in areas with  minimum winter temperatures of -15 -25 (but northern populations from Canada are resistant to -35 -45C).  It needs full sun to light shade.

Propagation: Seeds (no dormancy requirement, they germinate best at  25C) or by offsets (if available), or occasionally grafted.
