Growing Notes

Let this plant grow into an airy shrub, prune once or twice a year to maintain the size and shape, or shear into a formal hedge.

Some reports say this plant can survive brief drops as low as 18F with some damage.

This plant will also grow in part sun, but stretches out quite a bit and loses density.

Tolerates heavy soils as well as light, sandy soil.

One writer touts its ability to grow indoors in a sunny window. We haven't tried this!

Special Interest

One of the best seaside plants as it tolerates salt spray (but not seawater on its roots).

We've seen this plant in habitat thriving on bluffs a few meters from the high tide mark in southeast Australia.

Per San Marcos Growers, Westringia fruticosa was introduced into cultivation in California by William Walker at his Golden Gate Nursery in San Francisco in 1858.
