- Sow seeds directly outdoors from March to May.
- Alternatively, sow August to September for flowering the following year. Early sowings may produce flowers in the first year.
- Sow 5mm deep in well-prepared, well-drained soil.
- Keep the soil lightly watered until germination.
- Germination will usually occur 42-56 days after sowing if conditions are ideal and is best at 15-18c.
- When seedlings are large enough to handle, thin to around 30-40 cm apart.
- For extended displays, sow in succession or interplant with other wildflowers.
- Cut back plants once flowering finishes to manage self-seeding if required.
Viper’s Bugloss is a striking, wildlife-friendly biennial that produces tall spikes of vivid blue flowers with prominent pink stamens. Blooming throughout the summer, it is highly attractive to bees, butterflies, and other pollinators. Ideal for wildflower gardens, meadows, and sunny borders, this hardy plant thrives in poor, well-drained soils and adds height and vibrant colour to naturalistic planting schemes.
