Overview
Adenophora khasiana is a perennial, herbaceous, flowering plant that is native to the eastern Himalayas.
It has delicate blue to mauve bell-shaped flowers that last for several weeks make it an excellent addition to gardens, borders, or woodland settings.
It is quite hardy, though only marginally frost tolerant and attracts pollinators such as bees and butterflies, thereby supporting local ecosystems.
Once established, it requires minimal care, making it suitable for busy gardeners or low-maintenance landscapes.
Soil: It thrives in well-draining, slightly acidic to neutral soil. A loamy soil rich in organic matter is ideal for its growth. However, it can adapt to various soil types as long as they are well-drained.
Maintenance: Adenophora khasiana is relatively low-maintenance once established. Regular watering during dry spells and mulching to retain moisture are beneficial. Deadheading spent flowers can encourage prolonged blooming.
Diseases: While generally resilient, Adenophora khasiana may be susceptible to pests such as aphids, slugs, and snails.
It may also be prone to fungal diseases such as powdery mildew, especially in humid conditions. Adequate spacing between plants and good air circulation can reduce the risk of fungal infections.
Invasiveness: Not considered to be invasive.
Toxicity: There are no warnings of toxicity.
