Description
The Eriosyce subgibbosa subs. clavata, much better known under its old name Neoporteria clavata, is one of the recognized subspecies of Eriosyce subgibbosa which is a very variable plant that and has received numerous names. Eriosyce subgibbosa subs. clavata is one of the few Eriosyce that forms cylindrical stems.
Stem: Solitary, but sometimes branched, globular to columnar, up to 90 cm tall (or more), up to 10 cm wide. Grey-green, brownish-green or blackish-green. (“clavata” means “club shaped” and refers to the usually cylindrical stem shape of this form)
Ribs: up to 20
Spines: Nearly hiding the ribs, acicular, more or less long and dense, white, yellowish, golden yellow, brown, or nearly black, while older one became greyish.
Radial spines: 8-30, radiating,
Central spines: 4 (or more) stronger, straight or recurved and spreading, often darker at the tips..
Flower: Pretty relatively small up to about 4 cm long, bi-coloured with magenta, rose to the violet petal tips and pinkish-white, white or yellowish-white throat, giving the sensation of being fluorescent and being very difficult to photograph in good conditions because that particularity.
Blooming season: Blooms early in late winter to spring. It is advisable to leave them dry from middle of November to obtain fantastic flowering later in January/March.
Fruits: Ovoid to cylindrical, partly hollow at maturity, only scarcely woolly, apical areoles not spinescent.
Origin and Habitat
Coastal Chile (Approx from Valparaiso to Maule)
Habitat: Grows on rocky outcrop on costal terraces cliffs, slopes, often hanging from rocks, from areas with very arid Mediterranean climate to areas of transition between Mediterranean climate and humid forest. The species is common and abundant, and the population seems to be stable. The major threat is illegal collection and urbanization in tourism areas, but these are localized impacts.
Cultivation and Propagation
It is a summer grower species. Easy to cultivate but somewhat rot prone if kept in a non ventilated place. Require a very fast draining drying soil, water regularly in summer, but do not over-water.
Needs a full sun exposure (or light shade) Good heat tolerance. Hardy to at least -5°C ( but probably can tolerate - 10° C for brief periods).
Propagation: Usually propagated from Seeds. (seldom produces offsets)

Areoles: Large and woolly.
Spines: Partially hiding the ribs, needle like, more or less long and dense, white, yellowish, golden yellow, brown, or nearly black, while older one became greyish.
Radial spines: (8-)16-24(-40), 1-2(-3) cm long, radiating.
Central spines: 4 to 8, occasionally up to 16, stronger, up to 4 cm long,straight or recurved and spreading, often darker at the tips..
Flower: Pretty relatively small, tubular, up to about 3-5 cm long, bi-coloured with carmine petal tips and pinkish-white, white or yellowish-white throat, giving the sensation of being fluorescent and being very difficult to photograph in good conditions because that particularity. Inner tepals erect, acute, concealing the stamens.

Fruits: Ovoid to cylindrical, 1,5-2 cm long, 1 cm in diameter, red or reddish-green partly hollow at maturity, only scarcely woolly, apical areoles not spinescent.
Remarks: This species as many (very controversial) varieties.
Origin and Habitat
South Coquimbo, Chile.
Cultivation and Propagation
It is a summer-growing species of relatively easy cultivation that continues to be, a particular prize among collectors. This plant is extremely xerophytic, adapted to very dry soils and is quite susceptible to over-watering if kept in a non ventilated place.
Growth rate: Slow-growing.
Soil: Grow it in an open mineral, sandy-gritty cactus compost and provide a very good drainage.
Exposure: It is suited for sunny-brightly exposure, but can tolerate light shade. However it will do its best only with lots of sun and become stressed with inadequate light which could result in poor growth and unnatural shape. It has a good heat tolerance.
Watering: Water sparingly and keep it completely dry during winter. Mature individuals easily rot and die especially after transplanting so be extremely cautious with watering. Keep dry in winter or when night temperatures remain below 10° C. Water it less than average if in bigger pots.
Fertilization: Feed them once during the growing season with a fertilizer specifically formulated for cactus and succulents (high potash fertilizer with a dilute low nitrogen), including all micro nutrients and trace elements diluted to ½ the strength recommended on the label. They thrive in poor soils and need a limited supplies of fertilizer to avoid the plants developing excess vegetation, which is easily attacked by fungal diseases.
Special need: It is suited for airy exposures. Provide very good ventilation. Nearly all problems occur as a result of overwatering and poor ventilation, especially when weather conditions are dull and cool or very humid. They must have very dry atmosphere.
Hardiness: It likes warmth (recommended minimum winter temperature 5° C) But plants kept perfectly dry can easily survive to winter night temperatures below 0° C.
Pests & diseases: These cacti may be attractive to a variety of insects, but plants in good condition should be nearly pest-free, particularly if they are grown in a mineral potting-mix, with good exposure and ventilation. Nonetheless, there are several pests to watch for:
- Red spiders: Red spiders may be effectively rubbed up by misting the plants from above.
- Mealy bugs: Mealy bugs occasionally develop aerial into the new leaves and flowers with disfiguring results, but the worst types develop underground on the roots and are invisible except by their effects.
- Scales, thrips and aphids: These insects are rarely a problem.
- Rot: Rot is only a minor problem if the plants are watered and “aired” correctly. If they are not, fungicides won’t help all that much.
Propagation: Usually propagated from seeds (seldom produces offsets) or graft. The seeds can be sown in pots of fine, well-drained sandy soil, any time during the spring when temperatures are warm. Cover the seeds with a fine layer of grit and water from below with a fungicide to prevent damping off. For the 1-2 weeks cover the pots with a sheet of glass/clear perspex to keep the humidity levels high. Remove the glass and replace it with light shade-cloth and mist once or twice a day for the next two weeks after which most seeds should have germinated. From then on mistings can be reduced to every second and then every third day as the little plants grow. The seedlings should not be disturbed until they are well rooted after which they can be planted separately in small pots. Sometimes it is grafted to avoid root rot problems as plants grafted on an hardy stock are easy to grow and no special skill is required.

Eriosyce subgibbosa var. clavata has flowers of variable size, the large flowered form is sometime classified as forma “grandiflora” while the small flowered one is named forma “parviflora”. However the extent of variation in Eriosyce subgibbosa has led most authors to conclude that “grandiflora” and “parviflora” are not sufficiently distinct to deserve their own formal status.
Stem: Solitary, but sometimes branched, globular to columnar, up to 90 cm tall (or more), up to 10 cm wide. Grey-green, brownish-green or blackish-green. (“clavata” means “club shaped” and refers to the usually cylindrical stem shape of this form)
Ribs: up to 20
Spines: Nearly hiding the ribs, acicular, more or less long and dense, white, yellowish, golden yellow, brown, or nearly black, while older one became greyish.
Radial spines: 8-30, radiating,
Central spines: 4 (or more) stronger, straight or recurved and spreading, often darker at the tips..
Flower: Pretty relatively small up to about 4 cm long, bi-coloured with magenta, rose to the violet petal tips and pinkish-white, white or yellowish-white throat, giving the sensation of being fluorescent and being very difficult to photograph in good conditions because that particularity.
Blooming season: Blooms early in late winter to spring. It is advisable to leave them dry from middle of November to obtain fantastic flowering later in January/March.
