Senecio herreianus 'Purple Flush' - Information and Plant Care:
 
Senecio herreianus 'Purple Flush' is a stunning cultivar of Senecio herreianus Dinter, notable for its ability to develop a beautiful purple hue when exposed to strong light. This eye-catching succulent, formerly known as Kleinia gomphophylla, stands out with its unique, oval, bead-like leaves that are more elongated and spindle-shaped compared to the more commonly known Senecio rowleyanus. Its thick, somewhat erect stems and evenly spaced leaves form a captivating cascade, making it a popular choice for hanging planters or rockeries. As a low-maintenance plant, it’s perfect for those who appreciate beauty without the fuss. With proper care, this cultivar can thrive, showcasing its distinct coloration and charm.
 
 
Distinct Characteristics:
 
Growth Pattern and Size: Senecio herreianus 'Purple Flush' is a dwarf, rhizomatous, evergreen perennial with slightly branched, leaf-succulent stems. Initially growing low and creeping, its shoots eventually become pendant or scandent, forming large clusters over time. If allowed to trail along a rockery, its stems may root along their entire length, creating a lush, trailing effect.
Leaves and Coloration: The leaves of this cultivar are larger, less globular, and more elongated than those of its close relative, Senecio rowleyanus. They have a pointed, oval shape and a glaucous texture. Under strong sunlight, the plant's characteristic green leaves can turn a striking purple, adding a vibrant touch to any collection.
Flowers: Senecio herreianus 'Purple Flush' produces delicate, white, feather-duster-like flowers, similar to those of Senecio rowleyanus. These blooms, though small, are quite charming and add to the plant's overall appeal.
 
 
Senecio herreianus 'Purple Flush' Plant Care:
 
Light Requirements:
Prefers bright, indirect light but can tolerate some direct sun. For the best purple coloration, place the plant in a spot with plenty of light.
If grown indoors, a sunny windowsill is ideal. Avoid placing it in low light conditions as this can lead to a loss of the purple hue and leggy growth.
Watering:
Water thoroughly when the top 2-3 cm of soil is dry to the touch. During the active growing season, water more frequently, but reduce watering in winter.
Use the “soak and dry” method: water the soil thoroughly until water drains from the bottom, then let it dry out completely before watering again.
Soil:
Use a well-draining cactus or succulent mix to prevent waterlogging. Adding perlite or pumice to the soil mix can improve drainage and aeration.
Ensure the pot has drainage holes to avoid water retention, which can lead to root rot.
Temperature and Humidity:
Thrives in typical household temperatures between 18-24°C. It can tolerate slightly cooler conditions but should be protected from frost.
Humidity is not a major concern; average indoor levels are sufficient.
Fertilization:
Feed with a balanced, diluted succulent fertilizer once a month during the growing season (spring and summer).
Avoid over-fertilizing as this can lead to excessive, weak growth.
Pruning and Repotting:
Prune as needed to maintain desired shape and size. Remove any dead or damaged stems to encourage healthy growth.
Repot every 2-3 years in the spring to refresh the soil and provide more space for root growth.
 
 
Common Issues and Solutions:
Root Rot:
Caused by overwatering or poorly draining soil. Ensure the plant is not sitting in water and use a well-draining mix.
Pests:
Watch for common pests like spider mites, mealybugs, and aphids. If found, treat with neem oil or insecticidal soap.
Regularly inspect the plant, especially in hidden areas like the leaf axils and under the leaves.
Leaf Discoloration:
Yellowing leaves can indicate overwatering or poor light conditions. Adjust care accordingly.
If leaves are not turning purple, try increasing light exposure gradually.
 
 
Additional Tips:
 
Propagation: Senecio herreianus 'Purple Flush' is easy to propagate through stem cuttings. Simply cut a healthy stem, let it callous for a few days, and then plant in well-draining soil.
Ideal Placement: This cultivar thrives in hanging baskets where it can cascade gracefully. Ensure it gets plenty of light to maintain its vibrant coloration.
Handling: As a succulent, it can handle some neglect, making it a great choice for beginners. However, avoid sudden changes in light or water, as this can stress the plant.
 
 
Etymology:

This name likely alludes to the plant’s white, hairy fruiting bodies, which resemble an elderly man's head of hair. 'Herreianus' honors the German botanist Hans Herre, who specialized in succulents. The cultivar name 'Purple Flush' refers to the plant's unique ability to develop a beautiful purple hue when exposed to strong sunlight, making it a truly distinctive variety.
