Salmwood: complete guide

Cordia alliodora, known as salmwood, Spanish elm, or bois de Chypre, is a majestic tropical tree in the Boraginaceae family. Native to Mexico through tropical America, this species is renowned for its excellent timber and ornamental value.

Overview

Cordia alliodora is a graceful tree reaching up to 20 meters in tropical conditions. With its broad crown and dense foliage, it forms a perfect shade tree. This species is widely used in traditional construction and fruit production because of its hard, durable wood.

Appearance & Bloom

The tree features large, heart-shaped leaves with distinctive veining, creating unique texture. During the growing season, small yellowish-white flowers appear in terminal clusters. These flowers possess a subtle fragrance attracting various pollinators. The flowers give way to small stone fruits attracting numerous bird species.

Ideal Location

Plant salmwood in a fully sunny location with protection from strong wind. In tropical climates, the tree thrives in full sun. The tree tolerates partial shade in very hot conditions. In temperate climates, protected cultivation during winter months is essential.

Soil

The tree grows well in nutrient-rich, well-drained soils. Maintain pH between 6.0 to 7.5. In container cultivation use universal potting soil with added sand for better drainage. The plant is not critical about soil composition but appreciates fertile soil rich in organic matter.

Watering

Water regularly during growing periods, especially in hot and dry seasons. Do not allow soil to dry out completely. In container cultivation, water when the top 2 centimeters feel dry. Water less during winter. This tree has moderate water requirements.

Pruning

Prune in late winter or early spring. Remove dead, diseased, or crossing branches. Shape the tree toward desired form by gently shortening young shoots. This tree tolerates pruning well, responding with abundant new growth.

Maintenance Calendar

May through October: active growth period. Water regularly and monitor for pests. February through March: pruning season, inspect young wood. April: apply fertilizer for growth burst. November through January: slow growth with reduced watering.

Winter Hardiness

Frost sensitive; this tree grows in USDA zone 10a and higher. In temperate climates, protected cultivation is essential. Temperatures below 5 degrees Celsius cause defoliation. In tropical areas, no special precautions needed.

Companion Plants

Combine salmwood with other tropical shade trees like Ficus and Salix. Underplant with shade-tolerant species. This tree creates a microclimate where tender plants flourish.
