Vipers Bugloss
British native · Wildflower
Vipers Bugloss is a striking British native biennial or short-lived perennial, producing tall spires packed with vivid blue, funnel-shaped flowers. Its bristly foliage and dramatic shape suit dry, open ground, where it creates an exceptionally colourful focal point in a gravel garden, sunny bank or wildlife meadow.
Why grow it
For a dry, sunny site, few native flowers match Vipers Bugloss for pollinator activity. Each spike opens flowers over a long period, providing a continuous food source and a powerful blue accent. It is widely regarded as one of the best bee plants and is included among RHS Plants for Pollinators.
How to grow it
Give it full sun and sharply drained, poor to moderately fertile soil. Sandy, gravelly and chalky soils are ideal; avoid shade, rich feeding and waterlogged ground. Sow UK native-origin seed in autumn or early spring where it is to grow, lightly firming the seed into the surface. Alternatively, plant young specimens 30 to 45 cm apart with minimal root disturbance. Water only while establishing. Allow selected plants to set seed, as individual rosettes may flower then die after their second year.
Wildlife value
The blue flowers are extraordinarily popular with bumblebees, honeybees and many solitary bees, including leafcutter and mason bees where present. Hoverflies and butterflies also visit in warm weather. A group of plants can provide a busy nectar station from early summer onwards, especially in dry gardens where few other plants are flowering.
Tips
Wear gloves when handling its rough foliage and position it where its tall flowering spikes can rise through lower plants. Do not mulch with rich compost around it. Buy only UK native-origin seed or plants from reputable suppliers, rather than collecting seed from the countryside.
