Scientific Name

Eulychnia castanea f. varispiralis

Synonyms

Scientific Classification

Family: Cactaceae
Subfamily: Cactoideae
Tribe: Notocacteae
Genus: Eulychnia

Description

Eulychnia castanea f. varispiralis is a rare cactus with curly, whirly spiral growth that can be equally clockwise or counterclockwise. The stems grow up to 6.5 feet (2 m) tall and up to 4 inches (10 cm) in diameter.

Hardiness

USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).

How to Grow and Care

Eulychnia is not common in cultivation, and only collectors with a specific interest in the genus seem to grow them. It requires full sun or light shade to keep the plant compact with strong, colored spines. It tends to bronze in intense light, which encourages flowering and heavy spine production. A light shadow may be useful on the hottest summer days.

These cacti require light but regular watering in summer. Let the soil dry between waterings. Keep the soil dry in winter.

Eulychnias need to be kept in a cool place during winter rest. They are resistant to light frost if kept on the dry side before and during cold weather. Eulychnias are hardy to 28 °F (-2 °C) in short periods.

Eulychnia likes very coarse, mineral cactus soil mix but can become too elongated if the soil is too rich. Feed with a high potassium fertilizer in summer.

Origin

Eulychnia castanea f. varispiralis is a spiral form of Eulychnia castanea, a cactus native to Chile (along the coastline from Los Molles north to Talinay, Coquimbo).

Eulychnia castanea f. varispiralis - garden

Origin and Habitat: Garden origin (Nursery produced cultivar)

Description: This odd plant is known in cultivation under quite a lot of different names (among them, "spiralis", "varispiralis", "spiraliforme", "mostruosa", "monstrose", "monstrous" ) It is a variable cultivar of which we can distinguish at least four basic growing forms:
1) Columnar monstrous form: Characterized by a lumpy-bumpy monstrous surface, this is the more common form, about 60-75% of the new branch shows this monstrous morphology.
2) Columnar discoidal form: Characterized by green discs placed one on top of another in a heap. Only 20-30% of branches develop the typical discs.
3) Columnar spiral form: Characterized by curly, whirly spiral growth that can be equally dextrorotatory or levorotatory, this form is very appreciated by collectors but comparatively rare (about 5-15% of shots shows this admirable feature)
4) Crested form: Characterized by fan-like sculptural shapes comprising mix of the previously types, this form is very rare and prized.
Remarks: All this form are only growing variant of the same clone, each new branch must show one (or a mix) of the four growing mode and each plant is unique and different.

Cultivation and Propagation: This species presents no problems in cultivation and will do well in a sunny spot in a cactus house. These plants will tolerate sun and heat, but not extended periods of frost. The crested form is more frost sensitive and should not be kept at less than -0°C . Grow them in rich, porous, sandy soil, and let their soil dry out between waterings. If potted, repot in the spring, if their roots become cramped. Generally, they should be repotted every other year in order to provide fresh soil. However, this doesn't necessarily mean they'll need larger containers. Fill about a quarter of the pot with broken crocks, gravel, etc. to promote good drainage. After repotting, do not water for a week or more. The crested plants enjoy a warm sunny environment and for more speedy growth a light position on a higher shelf with light feeding and rainwater given to the bottom of the plant will ensure success, especially with rooted detached branches, which do well in these conditions.
Propagation: This plant is frequently grafted onto a **Myrtillocactus geometrizans*** trunk, but it is easily grown on its own roots. It can be increased by cuttings, which will take root in a minimum temperature of 20° C. Cuttings of healthy shoots can be taken in the spring and summer, Cut the stem with a sharp, sterile knife, leave the cutting in a warm, dry place for a week or weeks (depending on how thick the cutting is) until a callus forms over the wound. Once the callus forms, the cutting may be inserted in a container filled with firmed cactus potting mix topped with a surface layer of coarse grit. They should be placed in the coarse grit only this prevents the cut end from becoming too wet and allows the roots to penetrate the rich compost underneath. The cuttings should root in 2 to 6 weeks.
