Gardeners' Notes:

I have these shaped as clipped round balls in my garden. Each about 3 to 4 feet high. This is fast growing, and so its a terrific alternative to boxwood if you want this topiary ball look without waiting many years to get that effect. Love the silvery color of the foliage. There are different species of Westringia, some with white flowers, some with lavender flowers, and there is variation on the foliage color. Either way, this also grows in a large pot quite well, or also can be allowed to grow to become tall as a hedge, or unclipped for a more natural shut. Easy care, drought tolerant, not fussy about soil. Hardy in zone 8.

In cultivation, this is a dense, well-branched, fine-textured evergreen foliage plant that reaches 6 feet tall and 10 feet wide. Native to coastal eastern Australia, it is drought-tolerant once established and does well in coastal California with little irrigation---also tolerates the heat inland, and also performs well with good drainage in south Florida landscaping. Forms a neat symmetrical mound with minimal pruning, a good plant for formal gardens.

A great xeriscaping plant, it needs good drainage and does not tolerate wet feet. Salt tolerant.

This has become popular in the last 15 years, and dwarf and variegated cultivars are now available both in Australia and the US.
