Chihuahua Pine
Pinus leiophylla
A southwestern and Mexican pine unusual for sprouting from its base after fire and for cones that take two to three years to mature. Its slender blue-green needles and ability to resprout set it apart from most pines.

Overview
Chihuahua pine is a medium-sized conifer of the Madrean highlands, ranging from southeastern Arizona and southwestern New Mexico south through the Sierra Madre of Mexico. It is one of very few pines able to resprout from the base after fire or injury, a rare trait among conifers.
Its cones are also distinctive: they require two to three growing seasons to mature rather than the usual two, and they open slowly to release small winged seeds.
The tree grows in open pine-oak woodland on dry slopes, contributing to the fire-adapted character of those forests.
How to identify it
- Needles: slender, blue-green, 2.5–4 in long, typically in bundles of three (sometimes five in some varieties)
- Resprouting: can sprout new shoots from the trunk base after fire—unusual for a pine
- Cones: small (1.5–2.5 in), woody, taking 2–3 years to mature
- Bark: dark gray-brown, furrowed; lower trunk often shows basal sprouts
- Crown: rounded and open
- Size: typically 30–80 ft (10–24 m) tall
Care & growing
Grow in full sun with good drainage in a warm, dry climate.
- Water: drought-tolerant once established; benefits from summer monsoon moisture
- Soil: tolerates rocky, lean soils; avoid waterlogging
- Temperature: suited to warm-temperate mountain climates (about USDA zone 8)
- Feeding: minimal
- Propagation: from seed; note the multi-year cone maturation when collecting
Its resprouting ability makes it resilient to occasional damage.
Habitat & origin
Native to the Madrean sky islands of southeastern Arizona and southwestern New Mexico and widely through the mountains of Mexico, generally between about 5,000 and 9,000 ft elevation.
It grows in open pine-oak woodland on dry, rocky slopes shaped by periodic fire. It is uncommon in cultivation outside its native region.
Frequently asked questions
What makes Chihuahua pine unusual?
It is one of the few pines that can resprout from the base after fire, and its cones take two to three years to mature instead of the usual two.
Where does it grow?
From the sky-island mountains of southeastern Arizona and southwestern New Mexico south through the Sierra Madre of Mexico, in pine-oak woodland.
How big does it get?
Typically 30 to 80 feet tall, with a rounded, open crown of slender blue-green needles.
Is it fire-resistant?
It is fire-adapted: thick bark protects mature trees, and the rare ability to resprout from the trunk base helps it recover after burns.
