What is red cedar? Origin, taxonomy, and distribution
El Red Cedar, whose scientific name is Cedrela odorata, belongs to the family meliaceae and is widely known throughout America. It is also called American cedar o Mexican cedar, and enjoys great prestige due to its remarkable wood properties and versatile applications. genus Cedrela It groups together various species spread across tropical and subtropical regions of the American continent and has even been successfully introduced to parts of Africa, Oceania, and the southern United States, such as Florida. Furthermore, various synonyms have been used historically to refer to this species, highlighting its botanical and cultural significance.
Red cedar is naturally distributed from Mexico and all of Central America, covering countries such as Guatemala, Honduras, Costa Rica, Nicaragua, Venezuela, Colombia, Ecuador, Bolivia, Peru, Brazil, Panama and part of the Caribbean islands, including Cuba, Martinique, Antigua, and other Antilles. It is also present in South America as far north as Argentina. This adaptability has allowed it to spread to different ecosystems, primarily deciduous tropical forests and lowland areas up to approximately 1200 meters above sea level.
In some tropical archipelagos and islands, such as the Galapagos or certain Pacific islands, it is considered an invasive species because its seedlings tolerate shade and adult trees prevent the growth of other species by blocking light and releasing allelopathic compounds through their roots.
Botanical description and morphology of red cedar
El Red Cedar It can reach impressive heights, measuring between 30 and 45 meters, with diameters in adult specimens of up to 2 meters. On straight trunk It sometimes has buttresses at the base, an adaptation that gives it greater stability in shallow soils. Branches usually sprout from the upper half of the trunk, creating a globular or rounded, dense crown, very characteristic of the species.
La Cortex It shows different shades depending on the age of the tree; it is light grey and slightly rough in young specimens, while in adults it occurs deeply fissuredWhen you cut the bark, the inside is revealed. pink and fibrous, giving off a strong, bitter smell due to its essential oil content.
The compound leaves They are alternate and large, measuring 30 to 70 cm long, with between 5 and 11 pairs of leaflets per leaf. The leaflets are lanceolate, with entire edges and a smooth surface, with a striking color dark green on the upper side and greenish yellow on the undersideWhen squeezed they release a very characteristic alliaceous aroma.
The flowers They are arranged in panicles, generally shorter than the leaves. They are small in size, greenish cream color and have a soft perfume. Each flower measures between 6 and 9 mm, has a cup-shaped calyx and five petals, containing both male and female flowers in the same inflorescence.
El fruit of the red cedar is a oval woody capsule, among 2,5 and 5 cm long, which when ripe opens into five valves (occasionally in four), showing a star-shaped structure. Inside it houses winged seeds of about 2 to 2,5 cm which are effectively dispersed by the wind, facilitating their reproduction over large areas.

- Avoid overly compacted soils or soils with high water retention.
- Maintain a moderate watering rate, avoiding excess water that can weaken the tree.
- Apply fertilizers in small doses during planting and growth to promote establishment and strength.
El Red Cedar It is resistant, but certain pests such as Hypsipyla grandella (bud moth) can affect their development. Therefore, it is recommended to combine them with other trees in mixed plantations, which reduces the impact of pests and improves the biodiversity of agroforestry systems.
Reproduction, biological cycle and growth
El Red Cedar It reproduces mainly by winged seeds that are dispersed by the wind, each fruit can contain between 20 and 40 seeds. An adult tree can produce millions of seeds in a single season. Young trees may begin to flower between 10 and 15 years of life, depending on environmental and soil conditions.
La flowering It is produced annually, and the fructification It usually appears in the following months. The wood develops slowly, acquiring the properties that make it valuable only after several years of growth.
