About Bacopa

Let it snow! The Chaenostoma cordatum, aka Sutera cordata, cultivar ‘Snowflake’ offers a blizzard of crisp, white, five-lobe flowers and evergreen foliage on lush, trailing stems. A South African native, what we know today as C. cordatum has been the subject of a number of genus reassignments and common name changes since the early part of the 19th century and has been known at one time or another as Sutera diffusus, Bacopa cordata (which is technically incorrect, inasmuch as Bacopa is the genus for water hyssop), and simply “bacopa.”

This fast-growing plant blooms abundantly from late spring to first fall frost in sun, with adequate water. Although best known for its white flowers, bacopa also has cultivars that produce flowers in blue, pink, and purple. Bacopa is also grown as a ground cover.

C. cordatum is a winter annual or perennial in Zones 9 to 11 and treated as an annual elsewhere.

Planting

Bacopa can be propagated by cuttings, but gardeners are advised to purchase plants. 

The plant is not particular about pH or soil, but its medium must drain well. It can not tolerate standing water, which may lead to root rot. 

If you choose to plant Bacopa in a container or hanging basket in potting mix amended with compost or organic matter.

Bakopa, Sutera diffusus, Bacopa diffusus blooms with small multicolored flowers.
Bacopa looks beautiful when grown in baskets.

Growing

Provide bacopa with full sun to partial shade, with consistent moisture, or give it morning sun and afternoon shade. Note that extreme heat may cause it to lose vigor.

Water generously and regularly; avoid complete dryness. Bloom and bud drop may be a sign of drought stress. If this occurs and is not severe, continue watering and allow about 2 weeks for blooms to return. 

Apply a balanced liquid fertilizer (10-10-10) every 1 to 2 weeks.

Bacopa is self-cleaning; no deadheading is necessary. Prune to remove dead stems under foliage, if necessary.
