Growing Notes

Front-line coastal native, and thus a good choice for beach or bluff gardens, and windy sites in general.
Easily pruned to maintain height or increase density.
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).

More Info

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, the parent species, was introduced into cultivation in California by William Walker at his Golden Gate Nursery in San Francisco in 1858.
