Botanical Identification

Ecology

The ecology of Ocimum labiatum is characterized by its ability to inhabit diverse topographical settings across a significant vertical gradient. This species thrives within an elevational range that extends from a minimum of 305 m AMSL to a maximum of 2130 m AMSL. This broad altitudinal distribution suggests that the plant is ecologically adaptable, capable of surviving in both lowland environments and more temperate, high-altitude montane zones. Such a wide range indicates a resilience to varying atmospheric pressures, temperature fluctuations, and moisture availability inherent to different mountain elevations.

Elevational range max:

2130 m AMSL

Elevational range min:

305 m AMSL

Life history

The life history of Ocimum labiatum is characterized by its nature as a perennial plant, allowing it to persist through multiple growing seasons. Throughout its life cycle, it undergoes various developmental stages, beginning with seed germination that typically occurs in favorable environmental conditions. As a perennial, the plant establishes a robust root system that supports its continued growth and ability to regrow after periods of dormancy. During its active growth phases, it develops its characteristic leafy structure and eventually reaches reproductive maturity, producing inflorescences that facilitate seed production. The duration of its individual life stages can be variable depending on environmental stressors, nutrient availability, and climatic conditions, but its fundamental biological strategy is geared toward long-term survival and repeated reproductive cycles.
