Description

Aeonium haworthii 'Kiwi', commonly known as Aeonium Kiwi, is an exceptionally captivating succulent prized for its vibrant, tri-colored rosettes that evoke the appearance of the tropical kiwi fruit. This perennial member of the Crassulaceae family is a distinguished cultivated variety of Aeonium haworthii, a species indigenous to the rugged, sun-drenched landscapes of the Canary Islands, specifically Tenerife, La Gomera, and El Hierro. The 'Kiwi' cultivar was meticulously developed through selective breeding, primarily to enhance its unique aesthetic qualities. The plant is characterized by its compact, branching stems, typically reaching up to 60 cm in height, adorned with fleshy, spoon-shaped leaves arranged in dense rosettes. The foliage displays a remarkable color gradient: the outer leaves are a lush green, transitioning inwards to a bright yellow or creamy band, and often culminating in striking reddish-pink tips when exposed to ample sunlight and cooler temperatures. This intense coloration is a defining feature of Aeonium Kiwi, significantly contributing to its widespread popularity among succulent enthusiasts and gardeners worldwide. In its naturalized habitat, Aeonium haworthii thrives in rocky, coastal, and mountainous terrains, underscoring its profound adaptation to arid and semi-arid conditions.

Environment & Growth

Natural habitat for the parent species Aeonium haworthii is rocky coastal and mountainous regions of the Canary Islands, specifically Tenerife, La Gomera, and El Hierro. Climate zones: USDA Hardiness zones 9-11. Altitude range: Up to 600 meters in its native habitat. Annual rainfall needs: Adapts to low rainfall, typically thriving with 250-500 mm annually if well-drained, but relies on stored water and atmospheric moisture.

Care Tips

• Ensure adequate bright indirect sunlight to full sun for best coloration.
• Use a very well-draining soil mix to prevent root rot.
• Water only when the soil is completely dry to the touch.
• Protect from frost as it is not cold-hardy.

Propagation Methods

Cuttings: Take 10-15 cm stem cuttings in late winter/early spring. Allow the cut end to callous for 2-3 days in a dry, shaded area. Insert the calloused end into well-draining succulent soil. Do not water for the first week, then water sparingly until roots establish (typically 3-6 weeks). Division: Separate offsets (pups) that form around the base of the plant, ensuring each has some roots. Allow cut ends to callous before planting. Seeds: Propagation from seeds is possible but less common for cultivars and results in genetic variation. Seeds are very fine; sow on surface of moist, well-draining soil and keep warm and humid.

Common Problems

Common pests: Mealybugs (treat with rubbing alcohol on a cotton swab or insecticidal soap), Aphids (hose off or use insecticidal soap). Fungal diseases: Root rot (caused by overwatering; prevention is key), Powdery mildew (improve air circulation, use fungicide). Nutrient deficiencies: Rarely an issue with proper succulent soil mix; yellowing/stunting can indicate overwatering or lack of light rather than nutrient deficiency. Organic solutions: Neem oil for pests, proper watering and air circulation for fungi.
