Houghton's Kalanchoe

Houghton's Kalanchoe (Kalanchoe houghtonii) is a hybrid succulent plant belonging to the Crassulaceae family. It is widely recognized for its robust growth habit and is a cross between Kalanchoe daigremontiana and Kalanchoe delagoensis, inheriting the most resilient traits from both parent species.

The plant originates from tropical regions where it has adapted to arid and semi-arid conditions. In terms of cultivation, it is primarily grown in greenhouse environments or as an indoor ornamental plant in non-tropical zones. It thrives in conditions that mimic its natural habitat: bright light and very warm temperatures, while being extremely sensitive to frost.

Botanically, it features succulent leaves with serrated margins where a large number of plantlets develop. These plantlets serve as the primary method of reproduction, detaching easily and rooting in the soil with high success rates. This biological trait makes the species highly efficient and rapid at establishing populations in suitable environments.

Agronomic requirements center on well-draining, sandy-loam soils and a strict irrigation schedule. The crop must be allowed to dry out significantly between watering sessions to prevent root rot, which is the most common physiological disorder in this species. Balanced fertilization is required during the peak growing season to support its vigorous vegetative growth.

In practice, the plant is valued for its unique architecture and ease of maintenance in interior landscaping. Common pests include mealybugs and aphids, which can be managed with standard horticultural practices and careful environmental control. Maintaining good air circulation is essential to prevent fungal outbreaks in dense greenhouse stands.

• High drought resistance.
• Efficient vegetative propagation.
• Requires bright, filtered sunlight.
• Vulnerable to overwatering.
