Xiquexique gounellei subsp. gounellei – sculptural desert form with branching candelabra habit


Xiquexique gounellei subsp. gounellei is a striking, slow-growing cactus native to the arid landscapes of northeastern Brazil. Its thick, columnar stems branch from the base, forming dense, candelabra-like clusters covered in short, spiny tubercles. Each stem has a bluish-green tone with rough texture and scattered white spines, giving the plant a weathered, architectural appearance. This cactus thrives under dry, bright conditions and makes a bold statement as a living sculpture in warm indoor setups or greenhouse displays. Its subspecies status reflects subtle differences in rib count and spine length from related taxa, but it retains the same resilient, long-lived desert charm.


Stem traits and mature form

Structure: Columnar, cylindrical stems branching from the base to form multi-stemmed clumps
Surface: Bluish-green to grey-green, matte texture with prominent tubercles
Spines: Short, rigid white to grey spines arranged in tight clusters; denser in younger growth
Growth habit: Basally-branching, candelabra-style cactus with upright form
Indoor size: 60–100 cm tall when mature; spreads 40–60 cm across with age



Habitat origin and growing conditions
This subspecies occurs in dry Caatinga regions of northeastern Brazil, particularly in rocky outcrops and open shrubland where it endures intense sun, heat, and seasonal drought. It has adapted to survive long dry periods by storing water in its dense, fibrous stems and rooting deeply in gritty soils. When grown indoors or under glass, it needs a similarly dry and well-ventilated setting with high light exposure and minimal humidity.

Native region: Northeastern Brazil (Caatinga biome)
Habitat type: Arid scrub, dry woodland edges, rocky hillsides
Light requirement: Full sun to high-brightness indoors
Toxicity: Non-toxic; spines can still irritate skin – handle with care
Growth rate: Very slow-growing; forms dense clusters over years



Xiquexique gounellei care guide

Light: Requires full sun or intense artificial grow light indoors; avoid low-light corners
Watering: Water deeply and infrequently during the active season; allow soil to fully dry between waterings
Humidity: Prefers low humidity; ensure excellent airflow in enclosed spaces
Temperature: Thrives between 20–32 °C; protect from temperatures below 8 °C
Soil: Gritty cactus mix with large mineral content (pumice, coarse sand, perlite)
Repotting: Rarely needed – only repot every 4–5 years or when the container is full
Feeding: Apply cactus fertilizer diluted to half strength once every 6 weeks in spring and summer
Propagation: By cuttings or offsets; allow cut ends to callus before planting
Hydroponics: Not suitable – this cactus requires dry root zone and mineral substrate
Pruning: Not needed; remove dead stems or fallen spines only when necessary



Common problems and how to fix them

Soft or collapsing stems: Overwatering or poor drainage – let soil dry completely and inspect roots
Pale color: Not enough light – move to a sunnier location or supplement with grow light
Wrinkling: Natural during dormancy or post-watering delay; monitor moisture level and root health
Root rot: Can occur in organic-rich or soggy substrates; use only coarse, mineral-based mixes
Mealybugs: May hide in rib joints – inspect regularly and remove with alcohol swab if needed



Extra notes and display tips
This is a long-lived, sculptural cactus ideal for collectors who enjoy rugged, naturalistic forms. Its slow growth and drought resistance make it a great fit for sunny windowsills, open terrariums with dry base layers, or even custom rock gardens under glass. Use a clay or unglazed terracotta pot to help prevent moisture buildup and mimic its native dry root zone.


Etymology and taxonomy
The genus name “Xiquexique” is derived from indigenous Brazilian terms referring to this type of cactus. The species was originally described as Cereus gounellei by F.A.C. Weber and later transferred to Xiquexique by L. Diers and Esteves. The subspecies *gounellei* is the nominate form, distinguished by specific morphological traits including spine length, tubercle shape, and branching pattern.


FAQs about Xiquexique gounellei subsp. gounellei

Does it flower indoors? Rarely – flowering is more likely in older specimens under full sun. Outdoors it produces small tubular flowers followed by red fruits.
Is it frost-tolerant? No – it must be protected from cold. Keep above 10 °C at all times, especially in winter.
Can it grow in small pots? Yes, but it prefers wide, shallow containers with excellent drainage; growth may be slower in smaller setups.
