Introduction to Bacopa
Bacopa, also known by its Latin name Chaenostoma cordata, is a trailing perennial that is perfect for hanging baskets, containers, and providing ground cover at the front of borders. Originally from South Africa, Bacopa is grown as an annual in the UK due to its lack of frost hardiness, as it cannot survive temperatures below 5ºC. Its mass of tiny flowers, ranging in colors from white to pink to blue, bloom from June through October.
Where to Grow Bacopa
Bacopa thrives in both full sun and partial shade and can be grown in well-drained soil or containers filled with a quality peat-free compost. Its trailing stems, which can grow up to 65cm long, make it perfect for hanging baskets, where it can soften the edges of baskets and containers. Additionally, Bacopa’s spreading habit makes it a useful ground cover plant at the front of borders.
How to Plant Bacopa
If growing Bacopa from plug plants, pot them on and grow indoors until the danger of frost has passed. Harden the plants off gradually by placing pots outdoors during the day for 7-10 days, bringing them in at night. Once ready to plant out, choose a spot with well-drained soil or prepare a container or hanging basket filled with peat-free multi-purpose compost.
Care and Maintenance
Bacopa is a low-maintenance bedding plant. Regular watering is essential, especially during hot weather or if planted in hanging baskets or containers. Feed regularly throughout the growing season with a general-purpose liquid feed if growing in containers. Bacopa does not require deadheading as it will remain tidy and continue to flower into autumn. As a trailing plant, it does not need pruning for bushiness and will grow to around 20cm high.
Propagation
The easiest way to propagate Bacopa is by taking stem cuttings between March and August. Cut a shoot around 10-15cm long, trim the bottom just below a leaf joint, and remove the leaves from the bottom half. Insert the cutting into a pot of compost or place it in a jar of water until roots form, then pot it up.
Pests and Diseases
Bacopa is generally disease-free and not prone to many pests. Occasionally, aphids may appear, which can be removed by hand or left for birds to feed on. In severe cases, use a jet of water to spray off the pests.
