Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water Anchusa strigosa regularly, especially during dry spells, but avoid waterlogging. Allow the soil to dry out slightly between waterings.
Drought tolerant once established, but consistent moisture promotes better flowering and overall health. Reduce watering in winter.
Prune Anchusa strigosa after flowering to maintain a tidy shape and encourage a second flush of blooms. Remove spent flower stalks. If the plant becomes leggy, cut it back by about one-third to promote bushier growth.
Deadhead regularly for continuous flowering.
Propagate Anchusa strigosa from seeds sown in autumn or early spring. It can also be propagated by root cuttings taken in late winter or early spring.
Division of established clumps in early spring is another effective method to increase your plant stock.
Repot Anchusa strigosa every 2-3 years, or when the plant becomes root-bound. This is best done in early spring before new growth emerges.
Use a well-draining potting mix and choose a pot slightly larger than the current one to accommodate root growth.
