He cohune palm (also rain tree (Attalea cohune) care guide

The he cohune palm (also rain tree is Attalea cohune, a large, frost-tender tropical palm in the Arecaceae family. It is native from southern Mexico through Central America and parts of Colombia.

Attalea cohune grows best in full sun but tolerates light shade, especially while young. Provide bright, open exposure for stronger growth and a fuller crown.

Water a cohune palm regularly enough to keep the root zone moderately and evenly moist, particularly during hot or dry weather. Reduce watering only when temperatures are cool or rainfall is substantial.

Attalea cohune is frost-tender and should not be treated as a reliably cold-hardy palm. Established specimens may tolerate brief temperatures near the upper 20s Fahrenheit, but freezing can damage foliage or kill young plants.

Attalea cohune is best suited to frost-free tropical and warm subtropical areas of the United States, especially southern Florida and protected coastal locations. In colder regions, grow it in a container or protected conservatory.

Yes, Attalea cohune can tolerate light or shifting shade, particularly as a juvenile. Long-term growth and crown development are usually better with several hours of direct sun.

A mature cohune palm can become a very large landscape tree, with leaves reaching roughly 25 to 30 feet long and trunks eventually reaching about 50 to 60 feet in favorable conditions. Give it substantial overhead and lateral clearance.

Attalea cohune is generally unsuitable for a small yard because its mature leaves and eventual height require considerable space. It is better planted as a specimen in a large landscape, estate garden, or spacious tropical property.

Attalea cohune prefers warm, humid, tropical or subtropical conditions with limited temperature swings and adequate soil moisture. It performs poorly where winters bring recurring frost or prolonged cold.

Use deep, fertile, well-drained loam enriched with organic matter. The soil should retain moisture without becoming waterlogged, because prolonged saturation can damage the roots.

Established Attalea cohune may tolerate short dry periods, but it grows best with regular moisture. Extended drought can slow growth and cause leaf stress, especially in hot, sunny sites.

Slow growth is common when Attalea cohune is young because the trunk may remain underground for years. Cold, insufficient moisture, poor fertility, inadequate light, or root disturbance can slow it further.

Some cultivated descriptions report sharp structures on the trunk, petioles, or leaf rachises, although the extent can vary by plant and source. Position it away from paths, play areas, and frequently used outdoor spaces until the specimen is well identified.

Remove only completely dead or severely damaged leaves, using clean tools and avoiding cuts into the trunk or crown. Partly green leaves still contribute energy and should normally be left in place.

Plant Attalea cohune in a warm, frost-protected site with full sun to light shade and deep, well-drained soil. Set it at the same depth as its container soil and water thoroughly after planting.

A young Attalea cohune can be grown temporarily in a large container, but it is not a practical long-term houseplant because it eventually develops very large leaves and a substantial root system. Move it outdoors during warm weather only where temperatures remain safe.

In the United States, plant Attalea cohune in late spring or early summer after the danger of cold has passed. Warm soil and a long growing season help newly planted palms establish before winter.

Attalea cohune is propagated primarily from seed because it is normally a solitary palm and does not produce useful basal offsets. Use fresh, fully mature seed and provide warm, evenly moist conditions.

Fresh Attalea cohune seeds may germinate in roughly one to six months under warm conditions, although timing is variable. Germination is more reliable when the seed is kept warm, clean, and consistently moist but not submerged.

No, Attalea cohune cannot normally be propagated from leaf cuttings. Palms generally require viable seed or specialized tissue-culture methods, and a detached leaf will not produce a new plant.

Species-specific toxicity information for Attalea cohune is insufficient, so its safety for people and pets should be considered unknown. Do not allow children or animals to ingest its fruits, seeds, leaves, or other parts.

Attalea cohune fruits have traditional food and oil uses in parts of their native range, but household consumption should not be assumed safe without correct identification and reliable preparation guidance. Avoid eating fruit from an ornamental plant unless a qualified local source confirms its use.

There is not enough species-specific evidence to label Attalea cohune broadly invasive throughout the United States. Its outdoor suitability and potential spread depend on local climate, seed production, and whether viable seedlings establish.

Yes, mature Attalea cohune produces cream-colored flower clusters from within the crown. The species is monoecious, so male and female flowers occur on the same plant, though flowering may be uncommon in cultivation.

After flowering, Attalea cohune can produce large clusters of brownish-yellow to reddish-brown, ovoid fruits. The fruits contain seeds and have historically been used as a source of oil and other useful palm products.

There is no dependable cultivation age for flowering because growth rate varies with climate, soil, moisture, and plant size. Juvenile palms may remain trunkless for many years, and flowering generally requires a well-established, mature specimen.
