Kenya's diverse landscapes are home to a rich array of plant life, including several Cordia species. As part of the Boraginaceae family, the Cordia genus boasts around 300 shrubs and trees, mostly thriving in warmer regions globally. These plants not only enhance the visual appeal of their surroundings but also play pivotal roles in supporting local ecosystems. Let's delve into the distinctive Cordia species found in Kenya:
- Cordia sinensis: A Lifeline Along the Turkwel River
Also known as the bush Cordia or grey-leaved Cordia, is a small, multi-stemmed tree with a distinctive grey bark and Grey-green,sandpapery leaves with rounded or notched tips. Its fruits are orange-red like egg yolk with very sticky edible pulp.
Reaching up to 12 meters, it withstands harsh drought conditions, thriving in areas with just 600-1000mm of annual rainfall. Its intricate root system delves deep, extracting precious moisture from the depths and offering stability against the wind's fury. These adaptations allow it to flourish in areas where many other trees struggle.
Along the banks of the Turkwel River thrives the Cordia sinensis, a tree known for its vibrant orange berries. These fruits, though initially bitter, hold a special significance for the Turkana people. Women in the community have mastered the art of boiling the berries to remove the bitterness, transforming them into a nutritious and delicious food source for their families. This age-old practice not only provides essential vitamins and minerals but also serves as a testament to the community's deep understanding and appreciation of their natural environment.
The gum from the tree is also edible and its leaves and fruits provide nutritious fodder for goats, sheep, cattle, and camels, sustaining vital livestock populations in arid regions. The sweet, edible fruits, enjoyed by humans and monkeys alike, offer a valuable source of sustenance. Its strong, flexible wood is used for building poles, fences, and even tool handles.
