Geiger tree

The Geiger tree (Cordia sebestena) is a vibrant evergreen tree or large shrub belonging to the Boraginaceae family. It is highly valued in horticulture for its striking, trumpet-shaped orange-red flowers and dense, dark green foliage that provides excellent shade in tropical landscapes.

Native to the Caribbean and parts of Florida, as well as Central and South America, the Geiger tree is best suited for zones where temperatures remain consistently warm. It is highly sensitive to cold, making it unsuitable for cultivation in regions prone to frost without protected environments or indoor care.

Botanically, the plant is characterized by its rough, sandpapery leaves and its capacity for nearly year-round blooming. It typically grows to a height of 3 to 7 meters, depending on local soil conditions and moisture availability. The fruit is a small, hard, white drupe that contains seeds capable of natural propagation.

Cultivation requirements are relatively straightforward: the plant thrives in full sun and requires well-draining soil. It is remarkably salt-tolerant, which makes it an ideal candidate for coastal planting. Irrigation should be managed to allow the soil to dry out between waterings, as excessive dampness can be detrimental to the roots.

• Requires full sun for maximum blooming.
• Prefers sandy, well-drained soil types.
• Highly tolerant to salt air and winds.
• Can be pruned for shape and structure.

The Geiger tree is primarily utilized for aesthetic purposes in urban gardening and coastal landscaping. While it is generally robust, growers should monitor for common pests such as aphids or scale insects. Providing proper spacing and maintaining a clear canopy helps reduce the risk of humidity-related pathogens.
