Agave striata Zucc.
Narrow-leaf agave
The narrow-leaf agave is one of the most ornamental and distinctive agaves of central Mexico. It forms perfectly spherical rosettes of hundreds of linear, rigid grey-green to blue-green leaves that radiate from the centre like a sun or a vegetal hedgehog. It inhabits semi-arid zones of the Chihuahuan Desert and the arid areas of the central Mexican plateau, at altitudes of 1,200–2,400 m. Its compact character, drought resistance and unusual geometry make it one of the most sought-after agaves in specialised ornamental collections and contemporary low-maintenance gardens. Taxonomic note: A. striata and A. stricta are distinct species that are frequently confused; A. striata has paler, greyer leaves, while A. stricta tends toward greenish-reddish tones.

Overview
| Category | Classification |
|---|---|
| Family | Asparagaceae |
| Genus | Agave |
| Growth Habit | Very compact and spherical monocarpic rosette, slow-growing. Rarely produces basal offsets. The rosette can produce bulbils on the quiote. Flowers after 10–20 years and dies, eventually leaving small shoots. |
| Conservation Status | Least Concern (LC) globally. Wild populations are locally fragmented by grazing and extraction for the ornamental trade. Not on Mexico's federal special protection lists. |
| pH Target | 6.5–8.5 |
| Type | Calcareous to clay-stony, well-drained, poor; rocky soils of the plateau sierras |
Origin & Habitat
Morphology
Very numerous (200–400 per rosette), linear to subulate, 30–60 cm long and only 0.5–1 cm wide, rigid, grey-green to blue-grey with a faint paler central stripe. No marginal teeth. Terminal spine 2–3 cm, reddish-brown. Margin sometimes carries very fine corneous filaments.
ecoSpike or compact raceme inflorescence 2–4 m tall. Tubular flowers 4–6 cm, yellowish-green to reddish. They appear in the upper part of the quiote in dense clusters.
ecoStemless or with a very short trunk. The piña is small and dense. The spherical rosette architecture is achieved by uniform radial growth of hundreds of thin leaves from a very compact central point.
ecoFibrous and shallow root system, adapted to the calcareous and clay-stony soils of the central Mexican sierras. High efficiency in capturing light rain and dew.

Propagation Strategy
S
O
Every 3–4 years; use terracotta pots for greater substrate transpiration.
A single very light application of low-nitrogen fertilizer (cactus type) in spring. Avoid fertilization in autumn–winter.
Uses & Applications
Precautions / Toxicity
Low systemic toxicity. Terminal spines can cause puncture wounds. No cases of severe contact toxicity are known. Avoid prolonged contact of sap with eyes.

Plant Health
Heart rot by Erwinia spp. (bacterial) — the greatest risk; caused by stagnant water in the rosette. Irreversible.
Mealybug (Pseudococcus spp.) — hides among the dense leaves; difficult to detect; use isopropyl alcohol with a brush.
Agave snout weevil (Scyphophorus acupunctatus) — its larvae can devastate the piña without obvious external symptoms until it is too late.

"A. striata is frequently confused with A. stricta in the ornamental trade. The simplest distinction: A. striata has longer, greyer leaves with a fine central stripe, forming a larger sphere (40–80 cm in diameter); A. stricta has shorter, greenish-reddish leaves and a smaller, tighter rosette. Both are excellent xerophyte ornamentals but with slightly different cultivation requirements. In collections, label carefully."
