Beaucarnea stricta Lem.
Stiff-leaved beaucarnea
Beaucarnea stricta Lem. is one of the most elegant species in the genus, endemic to the Mexican states of Oaxaca and Puebla. Its name refers to its stiffer, more erect leaves (stricta = straight, rigid) compared to the typically drooping ones of B. recurvata. It is highly prized in botanical gardens for its more formal and majestic bearing. Like other Beaucarnea, it features the characteristic bulbous base that stores water and allows it to survive long periods of drought.

Overview
| Category | Classification |
|---|---|
| Family | Asparagaceae |
| Genus | Beaucarnea |
| Growth Habit | Perennial caudiciform tree; swollen bulbous base and well-defined columnar trunk. Leaves are notably stiffer and more erect than those of B. recurvata, creating a more vertical and orderly silhouette. Reaches 3–8 m in natural habitat. Slow growing. |
| Conservation Status | Formally poorly evaluated; endemic to Oaxaca and Puebla. Potentially threatened by habitat pressure in the Tehuacán-Cuicatlán Valley. Its range partly overlaps with that of B. gracilis. |
| pH Target | 6.0–7.5 |
| Type | Sandy loam to sandy, very well drained |
Origin & Habitat
Morphology
Linear leaves, shorter and stiffer than those of B. recurvata — 40–100 cm — with a markedly more erect and less recurved tendency. They are stiffer to the touch and remain more vertical. Shiny dark green color.
ecoSwollen bulbous base similar to B. recurvata but often narrower in relation to the trunk. Grey-brown fibrous and wrinkled bark.
ecoPaniculate inflorescences with white to cream flowers, similar to other species in the genus. Dioecious species; flowering in spring in adult plants.
ecoNotably more formal and vertical bearing than B. recurvata. The erect leaves give it a very differentiated rigid-palm appearance. In botanical gardens it is often more striking than B. recurvata precisely because of this aspect.

Propagation Strategy
- 1 Soak seeds in warm water 24 hours
- 2 Sow in 50% potting mix + 50% perlite, cover with 3 mm
- 3 Keep moist at 22–28 °C; germinates in 2–4 weeks
- 4 Transplant when reaching 5 cm
- 1 Separate basal offsets of minimum 10 cm with sterile knife
- 2 Callous for 5–7 days dry
- 3 Plant in draining mix; first watering after 2 weeks
- 4 Roots in 4–8 weeks at 22–26 °C
T
Paradoxically too little water (some leaves yellow)
Every 2–3 years in spring; to a pot 2–3 cm larger
Balanced fertilizer diluted to 50% once a month in spring-summer. No fertilizer in autumn-winter.

"B. stricta was described by Charles Lemaire in 1861, the same year as B. recurvata. The difference in leaf rigidity between both species is genetic, not cultural — B. stricta will always maintain stiffer, more erect leaves even in low light conditions, although insufficient illumination will make them longer and less compact. It is the second best-selling Beaucarnea in the European trade after B. recurvata."
