1. Etymology: The name Hildewintera hybrid Humkes Klein Gelbe combines elements derived from the plant's lineage and appearance. "Hildewintera" refers to the parent genus, named in honor of the German botanist Kurt Winter, who specialized in cacti. "Humkes Klein Gelbe" translates from German to "Humkes Little Yellow," indicating a cultivar developed by Humkes, characterized by its small yellow blooms.
2. Origin of Plant: The Hildewintera hybrid Humkes Klein Gelbe is a cultivated hybrid, resulting from cross-breeding different species within the Hildewintera genus, commonly known as the "Monkey's Tail" cactus. These plants are native to the mountainous regions of Bolivia, but this specific hybrid is developed through horticultural efforts to enhance its ornamental features.
3. Technical Description:
- Family: Cactaceae
- Genus: Hildewintera
- Form: Columnar growth with trailing stems, which can grow up to 1-2 meters long.
- Stem: Cylindrical, green with areoles that bear soft, hair-like spines.
- Flowers: Bright yellow blooms typically emerging from the sides of the stems. The flowers are funnel-shaped and around 5-7 cm in diameter.
- Blooming Period: It usually blooms in spring and summer, offering profuse and striking yellow flowers.
- Fruit: If pollinated, it produces small red or reddish-purple fruits.
4. Conservation Status: As a hybrid created through horticultural practices, there is no direct conservation status in the wild for Hildewintera hybrid Humkes Klein Gelbe. However, its parent species, being part of the broader cactus family, can face threats from habitat loss and illegal collection. It is encouraged to source these plants from responsible and sustainable growers.
5. Care Instructions:
- Light: Requires bright, indirect sunlight. It can tolerate full sun but needs some protection during the harshest midday rays.
- Water: Water sparingly; allow the soil to fully dry out between waterings. Reduce watering further during winter months when the plant is dormant.
- Soil: Use a well-draining cactus mix to prevent root rot.
- Temperature: Prefers warm conditions but can withstand temperatures down to around 10°C (50°F). Protect from frost.
- Humidity: Thrives in low humidity; ensure good air circulation.
- Fertilizer: Feed with a balanced cactus fertilizer during the growing season (spring and summer) every 4-6 weeks.
- Propagation: Can be propagated through cuttings. Allow cut ends to dry and callous for a few days before planting in well-draining soil.
