Cape Sundew (Drosera capensis) - Seeds

The Cape Sundew belongs to the sundew family (Droseraceae) and is a true classic among carnivores (carnivorous plants). It is particularly popular with beginners because it is robust and grows quickly.

Origin and natural habitat

As the name suggests, the Cape Sundew originates from the Cape region in South Africa. There, it grows in damp, marshy, and nutrient-poor areas, often on riverbanks or in bogs. The climate there is subtropical, meaning the plant is accustomed to a lot of sun and mild temperatures.

Appearance and growth habit

• Leaves: The plant forms a basal rosette of strap-shaped leaves up to 15 cm long.

• Tentacles & Sticky traps: The upper surfaces of the leaves are densely covered with reddish glandular hairs (tentacles). At their tips are tiny, glittering droplets of a sticky secretion. This "morning dew" (hence the name) emits a sweet scent that attracts insects.

• Flowers: In summer, the plant produces a leafless flower stalk up to 30 cm long (so that pollinators do not accidentally end up in the traps). On it grow several small, usually brightly pink or purple flowers, which often only open for a single day.

• Growth: Over time, the Cape Sundew can form a small stem as the lower leaves die off and the plant continues to grow upwards.

Location and care (cultivation)

• Light: Drosera capensis is extremely light-hungry. A south-facing window with full sun is ideal. The more sun the plant gets, the more intensely its sticky tentacles turn red. In summer, it likes to be outdoors in full sun.

• Water: Tap water is pure poison! The plant may only be watered with rainwater, distilled water, or osmosis water. It is best to keep it in the so-called tray method: The pot stands permanently in a saucer filled with approx. 1-2 cm of water.

• Substrate: Normal potting soil is deadly. Special, nutrient-poor carnivorous plant substrate is required (usually a mixture of unfertilized white peat and quartz sand). Special substrate available here.

• Wintering: The plant can be cultivated warm on the windowsill all year round. However, it also tolerates cool wintering at 5–10 °C (then water a little less).

🌱 Sowing instructions and propagation

Propagating Drosera capensis is incredibly easy – often so easy that it propagates itself.

1. Seeds: The plant is self-pollinating and produces thousands of tiny, dust-like seeds after flowering.

2. Light germinators: The seeds must not be covered with soil! Simply sprinkle them on well-moistened carnivorous plant substrate.

3. Conditions: Keep the substrate very wet and ensure high humidity (e.g., stretch cling film with small holes over the pot or place it in a mini greenhouse).

4. Germination period: In a bright and warm place, the seeds often germinate after just 2 to 4 weeks.

5. Alternatives: Besides sowing, the plant can also be easily propagated via leaf cuttings or root cuttings.

💡 Interesting facts and curiosities

• The "Embrace of Death" (Thigmotropism): If an insect gets stuck to the sticky droplets and struggles, the plant registers the mechanical stimulus. Within minutes to hours, the entire leaf actively curls around the prey to bring as many digestive glands as possible into contact with the insect.

• Digestion: The plant excretes enzymes that decompose the insect. The dissolved nutrients (especially nitrogen and phosphorus, which are lacking in the soil) are absorbed through the leaf. After that, the leaf unrolls again, and the empty chitin shell of the insect blows away in the wind.

• The "weed" of the carnivorous plant scene: Because the Cape Sundew is so robust and self-sows almost explosively through its countless seeds, it often spontaneously appears in other pots. Among collectors, it is therefore affectionately-jokingly referred to as "carnivorous weed."

• Feeding unnecessary: You don't need to feed the plant indoors. The few fungus gnats or fruit flies it catches itself are completely sufficient as fertilizer. Meat or cheese would only cause the leaves to mold.
