Origin and Common Names
Crinum walteri Overkott, commonly known as Walter’s Crinum, is a plant species that is endemic to West Africa. It is named after Reinhard Overkott, a German botanist who discovered this species. Walter’s Crinum is a member of the Amaryllidaceae family, which is one of the largest families of flowering plants. It is mostly grown in Nigeria, where it is considered as a valuable medicinal plant.
Appearance and Characteristics
Walter’s Crinum is a bulbous plant that grows up to 1.2 meters tall. It has long and broad leaves that can grow up to 1 meter in length. The leaves are dark green in color and can be up to 10 cm in width. The plant produces clusters of large, trumpet-shaped flowers that are purplish-pink in color. The flowers can grow up to 15 cm in diameter.
The bulbs of Walter’s Crinum are large and onion-like in shape. They are covered by a brownish paper-like skin and often produce several shoots. The bulbs can be propagated by separating the shoots, which can then be planted in well-draining soil. The plant grows best in warm and humid conditions, and requires regular watering and fertilization to thrive.
Uses
Walter’s Crinum has been traditionally used in West African medicine to treat various ailments. The bulb of the plant is believed to have analgesic, antipyretic, and anti-inflammatory properties. It is often used to treat headaches, fever, and inflammation. The leaves of the plant are also used to treat wounds and skin diseases.
Walter’s Crinum is also a popular ornamental plant due to its large and showy flowers. It is often grown in gardens and parks as a decorative plant, and is suitable for use as a cut flower. The plant is also considered as a valuable source of nectar for bees and other pollinators.
Light Requirements
Crinum walteri Overkott prefer partial shade to full sun, with a minimum of four hours of direct sunlight per day. Although they can tolerate full sun, too much exposure to direct sunlight can cause the leaves to dry out and scorch. In areas with hot summers, providing some shade during the hottest parts of the day can help prevent stress and keep them healthy.
Temperature Requirements
These plants thrive in warm temperatures and cannot tolerate frost. Ideally, temperatures should be above 60°F (15.5°C) year-round. The optimal temperature range for growth is between 70°F (21°C) and 85°F (29.5°C). Extreme fluctuations or prolonged exposure to temperatures outside of this range may cause stunted growth or even death. In colder climates, Crinum walteri Overkott should be grown in containers that can be brought indoors during the winter months.
Soil Requirements
Crinum walteri Overkott prefer a well-draining soil that is rich in organic matter. A pH range of 6.0-7.5 is optimal, although they can tolerate slightly acidic to slightly alkaline soils. These plants do not do well in heavy clay soils with poor drainage, as this can lead to root rot and other problems. To improve drainage in heavy soils, amend the soil with organic matter such as compost or peat moss. Adding a layer of mulch around the base of the plant can also help to retain moisture and improve soil structure.
Cultivation Methods for Crinum walteri Overkott

Propagation of Crinum walteri Overkott
Crinum walteri Overkott, commonly known as Walter's Crinum, is a beautiful plant identified by its strongly scented flowers and long, strap-like leaves. It belongs to the family Amaryllidaceae and is native to West Africa.
Propagation methods of Crinum walteri Overkott
There are two primary methods of propagating Crinum walteri Overkott, and they include:
- Division: Crinum walteri Overkott can be propagated through division. To do this, wait until the plant is mature enough and has formed several offsets around the base. The offsets will have their roots and can be separated from the parent plant by cutting through the rhizome using a sharp, sterile knife. Ensure that each division has healthy roots and leaves before planting it in a new pot or site.
- Seeds: Another way to propagate Crinum walteri Overkott is through seeds. Start by collecting seeds from mature plants, removing them from the fruit, and soaking them in water to soften their outer coating. Plant the seeds in a well-draining potting mix and keep the soil moist. The seeds usually germinate within two to three weeks.
Whichever propagation method you choose, ensure that the plant is well-watered and placed in a warm, bright area after division or sowing seeds. Avoid exposing the plant to extreme temperatures or direct sunlight as it can cause stress or damage to the new roots.
With proper care, Crinum walteri Overkott can be successfully propagated and will reward you with its stunning foliage and fragrant flowers.
