Escobaria minima

Escobaria minima (syn. Coryphantha minima) is a rare species of cactus known by the common names Nellie cory cactus, Nellie's pincushion cactus, birdfoot cactus, and others. It is a very popular species among cactus collectors. This is one reason why it is a highly endangered species in the wild today. [1] This cactus is found only in Brewster County, Texas, in the United States, where there are three populations remaining near Marathon. [1] [2] The cactus is limited to one outcrop in the Marathon Uplift, where it grows in rocky novaculite soils. [3] [4] It was added to the endangered species list in 1979. [4]

Gardeners' Notes:

On Dec 27, 2010, dave12122 from East Haddam, CT wrote:

This could be a Zone 6 plant, but is very prone to rotting if the soil is wet in the winter or early Spring. Cold temperatures alone do not seem to bother it, but the combination of wet soil and cold can be deadly. The flowers are relativley large considering the size of the plant. This certainly is worth a gamble.

Birdfoot Cactus, Nellie Cory Cactus Escobaria minima, is Endemic to Texas and is classified as an Endangered species.


Escobaria minima - garden

Accepted Scientific Name: Escobaria minima (Baird) D.R.Hunt
Cact. Succ. J. Gr. Brit. 40(2): 30 (1978)

Origin and Habitat: Chihuahuan desert in the USA, they are found from only three populations, all in a tiny area of Brewster County, Texas.
Habitat: Grows in desert grassland, usually among the chips of weathered and physically fractured Caballos Novaculite rock (a quartz-like material). This species is now known only from three small sites

  • Escobaria minima (Baird) D.R.Hunt
    • Coryphantha minima Baird
    • Coryphantha nellieae Croizat
    • Escobaria nellieae (Croizat) Backeb.
    • Mammillaria nellieae (Croizat) Croizat

Description: It is a tiny cactus with rounded, single stems up to 2,5cm tall and 6-17 mm wide, occasionally with a short tap root tubercles 2 to 4 mm wide. A cultivated plant can be slightly larger, and clumped .
Spines: The plant is crowded with thick, corky, white spines (1 to 4 centrals, 4 to 6 mm long 13 to 23 radials, 3.5 to 5 mm long)
Flowers: Numerous, pink, up to 2.5 cm in diameter, 1.5 cm long. The flowers are easy to pollinate, and produce around thirty seeds per fruit.
Blooming season: It blooms in several flushes, primarily in May, but the blooming period lasts from March until June.
Fruit: It produces ovoid, green fruit (1.5-5 cm long) that ripens from June to October.
Remarks: Escobaria minima and Escobaria hesteri (From an adjacent hill) are two miniature plant which resemble dwarf races of Escobaria vivipara, to wich they shares some characteristic, but much smaller in all parts. They can survive to –25°C in dry-winter regions.

- This is the smallest Escobaria, a real gem, and very beautiful. Plants flowering in cultivation do not self-pollinate, but are easy to hand pollinate, and produce around thirty seeds per fruit. (Escobaria minima) Photo by: Andrea B.

Cultivation and Propagation: Very slow-growing, but easy to cultivate. Water regularly in summer, but do not over-water. It prefers a completely dry place during winter with much drainage.

Propagation: Easy to propagate from seed, cuttings and grafting.
