Disa Uniflora, also known as the Pride of Table Mountain, is a stunning orchid species that is native to South Africa.
It is a popular sight for hikers and nature enthusiasts who visit Table Mountain National Park.
The unique and vibrant flowers of Disa Uniflora have made it a symbol of South African flora and a must-see for tourists.
The orchid’s name, Disa Uniflora, comes from the Greek word “dis,” meaning two, and the Latin word “uniflora,” meaning one flower.
This name is fitting as the plant typically produces a single, large, and brightly colored flower that stands out against the greenery of Table Mountain.
Disa Uniflora is an epiphyte, meaning it grows on other plants or trees, and it is commonly found in the wetter areas of the mountain, such as streams and waterfalls.
Despite its beauty, Disa Uniflora is a delicate species that is threatened by habitat loss and climate change.
As such, it is important for visitors to Table Mountain National Park to appreciate the orchid’s beauty from a distance and avoid damaging its habitat.
In this beginner’s guide, we will explore the unique characteristics of Disa Uniflora and provide tips for observing it responsibly.

The flowers bloom in the summer months, typically from December to February, and are pollinated by sunbirds and other nectar-loving birds.
Overall, Disa Uniflora is a fascinating and beautiful plant that is well worth discovering for anyone interested in South African flora or orchids in general.
Botanical Characteristics
Morphology
Disa uniflora, also known as the Pride of Table Mountain, is a terrestrial orchid that can grow up to 50 centimeters tall.
It has a single stem that is covered in small hairs and can grow up to 10 leaves that are arranged in a spiral pattern.
The leaves are long and narrow, with a pointed tip and a smooth texture. They can grow up to 20 centimeters long and 2 centimeters wide.
The flowers of Disa uniflora are the most striking feature of this orchid. They are large and showy, with a bright red or pink color.
The flowers are arranged in a single spike that can grow up to 20 centimeters long and can produce up to 20 flowers.
Each flower has three sepals and three petals, with the middle petal forming a distinctive lip that is shaped like a slipper.
Reproductive Biology
Disa uniflora is a self-pollinating orchid, which means that it does not rely on pollinators to reproduce.
The flowers produce a sticky substance that traps pollen, and the pollen is then transferred to the stigma of the same flower.
The seeds of Disa uniflora are very small and light, and they are dispersed by the wind.
The flowering season of Disa uniflora is from January to March, and the flowers can last for up to six weeks.
After the flowers have faded, the seed pods will begin to develop and will eventually split open to release the seeds.
Disa uniflora is a slow-growing orchid and can take up to five years to reach maturity.
Cultivation and Care
Growing Conditions
Disa Uniflora is known for its ability to thrive in a wide range of growing conditions.
However, it is important to note that the plant prefers cool temperatures and high humidity.
It is best grown in a greenhouse or a shaded area with good air circulation. The plant also requires well-draining soil that is rich in organic matter.
Propagation Methods
Disa Uniflora can be propagated through seeds or division.
When propagating through seeds, it is important to note that the seeds require a period of cold stratification before they can germinate.
Division is typically done in the spring when the plant starts to show new growth.
To successfully propagate Disa Uniflora, it is important to follow these steps:
- Fill a pot with a well-draining soil mix.
- Water the soil to ensure it is moist but not waterlogged.
- Sow the seeds or plant the divided sections in the soil.
- Cover the pot with a plastic bag or place it in a humidity dome to maintain high humidity levels.
- Place the pot in a shaded area with good air circulation.
- Water the plant regularly, ensuring that the soil remains moist but not waterlogged.
- Once the plant has established roots and new growth, it can be transplanted into a larger pot or into the ground.
By following these simple steps, Disa Uniflora can be easily propagated and grown in a variety of growing conditions.
Conservation Efforts
Threats to Disa Uniflora
