These Seven Marvelous Plants Define Kenya's Montane Regions

Kenya’s high-altitude regions are a habitat for some iconic plants and flowers that would give any enthusiastic floral designer an idea or two for their next floral design. Some of the plants found in these regions include:

The Giant Groundsel (Dendrosenecio Keniodendron) Is a Towering Marvel

One of the most iconic plants of the montane regions is the Giant Groundsel, scientifically known as Dendrosenecio Keniodendron. Standing tall as though they are the custodians of the mountains, these giant senecios can reach staggering heights of up to 15 meters. 

Their magnificent silver-green leaves form rosettes that crown their sturdy stems, which are adorned with soft, woolly hairs to protect them against the chilly mountain winds and the extremely cold conditions

The Giant Groundsel predominantly graces the moorland regions of Mount Kenya and the Aberdare Range, adding an air of resplendence to these landscapes. But their true splendor lies in their blooming phase, when they produce exquisite clusters of white flowers. 

These floral displays form part of the nourishment for the unique montane fauna, including varieties of insects and high-altitude birds.

The Colorfulness of Lobelias

In the montane regions, one can't help but be intrigued by the fascinating Lobelia species. Among them, Lobelia Deckenii and Lobelia Telekii stand out as the most prevalent representatives of this floral family.

Lobelia Deckenii subsp. Keniensis is the variety of Lobelia Deckenii that occurs on Mount Kenya, between 3,300 and 4,600 m (10,800 and 15,100 ft). It boasts tall spikes of striking blue flowers that almost pierce the sky, adding a hint of elegance to the mountain slopes. These blossoms provide a much-needed source of nectar for hummingbirds and sunbirds, which flit among the flowers, enriching the region's mystical charm.

Lobelia Telekii, on the other hand, is a species of flowering plant in the family Campanulaceae, that is found only in the alpine zones of Mount Kenya, Mount Elgon, and the Aberdare Mountains. These lobelias create a stunning floral backdrop for the peaks, making the montane regions of Kenya a true haven for nature enthusiasts and botanists alike.

St. John's Wort (Hypericum Perforatum)

Amid the lush montane forests, a number of flowering plants of the St. John's Wort species, belonging to the Hypericum genus, also find refuge. Known for medicinal properties, this plant has been used for centuries to treat various ailments, including depression and skin conditions. The leaves and bright yellow flowers of St. John's Wort contain compounds believed to have therapeutic benefits, making it a valuable resource for traditional healers and modern medicine alike.

The Hypericum Keniensis, a species of giant St John’s Wort is found in the cloud woodland and parkland of Mount Kenya National Park. This flowering plant grows in the regions predominated by Hagenia Abyssinica and Hypericum Revolutum in the mountainous highlands.

Further to its medicinal value, St. John's Wort adds a splash of sunshine to the montane landscapes. Its cheery blooms attract butterflies and bees, transforming the forest clearings into bustling hubs of activity and guaranteeing the continuation of fauna’s existence in these lofty habitats.

Alchemilla (Lady's Mantle) Dubbed Nature's Dewdrop Collectors

The montane regions also host the delicate and graceful Alchemilla species commonly known as Lady's Mantle. Named for the resemblance of their leaves to the folds of a maiden's cloak, Lady's Mantle has long been admired for its outstanding beauty.

These plants have a special talent for collecting dewdrops, which delicately bead on their leaves in the early morning hours. This feature, combined with their soft, fuzzy appearance, makes them a favorite subject for photographers seeking to capture the ethereal essence of the montane regions.

Helichrysums Are the Everlasting Flowers at High Altitude

In Kenya’s highlands, Helichrysums, often referred to as ‘everlasting flowers’ or ‘strawflowers,’ flourish in abundance. These hardy plants boast vibrant, colorful blooms that retain their brilliance even after drying, hence their poetic name everlasting flowers.

Helichrysums add quite some color to the montane landscapes, creating a delightful contrast against the lush greenery and rocky terrains. These flowers are often used in traditional medicine and are treasured for their essential oils, which hold therapeutic and aromatic value.

African Redwood (Hagenia Abyssinica) Is Another Forest Guardian

The montane forests of Mount Kenya and the Aberdare Range find yet another majestic guardian in the African Redwood, scientifically known as Hagenia Abyssinica. Also known as the East African Rosewood, this evergreen tree has numerous other names such as Mukulungu, Mdobore, or Mlozilozi in different local languages. It has glossy, pinnate leaves and reddish-brown bark, and dominates the canopy of these highland forests. 

Native to the high-elevation Afromontane regions, the African Redwood plays a vital role in maintaining the ecological balance of the montane areas. Its dense foliage provides shelter and food for a plethora of wildlife, from forest elephants to colobus monkeys. 

Additionally, the tree's fallen leaves act as a natural mulch, enhancing the soil and supporting the growth of other plant species in this biodiverse ecosystem.

Alpine Bamboo (Yushania Alpina) Is a Versatile High-Altitude Plant

The alpine bamboo also stands tall as one of the most versatile plants in the montane forests. Species like Yushania Alpina form dense stands, providing a natural barrier against soil erosion on steep mountain slopes. The bamboo thickets also serve as vital corridors for wildlife movement, allowing various species to traverse between forest fragments.

Over and above its ecological significance, bamboo is an essential resource for local communities in the montane regions. Its culms are used for construction, crafts, and even as a source of food. Plus, the gentle rustling of bamboo leaves in the mountain breeze adds to the sense of serenity in these surreal landscapes.
