Borzicactus sepium aka Borzicactus Sepium

Borzicactus sepium is a spiny cactus from the tropical Andes. Its native range runs from southwest Colombia into Ecuador. It belongs to the cactus family, Cactaceae. Kew describes its form as a succulent shrub or subshrub. The plant grows in places with a marked dry season. Its wild sites include dry hills and valleys. Records place it at 4,920–11,480 feet [1,500–3,500 metres]. One cultivation account gives an upper limit of 12,140 feet [3,700 metres].

The stems form narrow columns that may lie along the ground. Others rise upward rather than staying flat. They reach about 4.9 feet [1.5 metres] in height. Each stem can measure about 0.13 feet [0.04 metres] across. A stem may stay single, with no branches. Other plants make a few branches near the base. Useful Tropical Plants describes the plant as evergreen. Its account gives no detailed leaf or bark traits. The spiny stems provide the main description of its form.

Hummingbirds pollinate the flowers, according to Useful Tropical Plants. The supplied account gives no flower colour or bloom season. The round fruits measure about 0.066 feet [0.02 metres] across. Their skin ranges from green with brown tones to yellow-green. Inside, white flesh holds many small seeds. People gather the fruit from wild plants for food. They eat it raw rather than needing to cook it. The source also records local use of the flowers. People drink a flower infusion as a traditional bronchitis treatment. This record does not establish that the treatment works.

In cultivation, this cactus needs a sunny site. The soil must drain well and stay near neutral. Keep the plant almost dry during its dormant season. These needs fit its origin in dry Andean country. The evidence gives no cold-hardiness zone or frost limit. It also gives no species-specific pest or disease details. Useful Tropical Plants lists no known hazards. That statement does not confirm safety for pets or people.

People sometimes grow this cactus as a living fence. Such plantings serve to mark barriers. The source reports a broad range and locally large populations. Some populations grow within protected areas. Its cited 2017 IUCN assessment lists Least Concern. That account identifies no major threats to the species.
