Westringia 'Lilac Gem (Lilac Gem Coast Rosemary) - A dense evergreen fast growing upright dense-growing shrub that likely will reach 6 feet tall or better by as wide with leathery 1 inch long gray-green leaves that are white beneath that radiate out from the dark stems in evenly spaced whorls. The clusters of attractive pale lilac flowers are produced primarily in spring with a scattered bloom throughout the year. Plant in full sun to light shade. This plant should prove to be dry growing, seaside tolerant, and tolerating cold down to at least 25 degrees F like other similar Westringia cultivars that we have longer experience with. This plant was named by us after it was discovered by our shipping manager Gene Leisch as a spontaneous seedling hybrid growing in the demonstration garden near our sales office, where many other Westringia cultivars are growing. It clearly looks to have foliage similar to the white flowering Westringia fruticosa, but with flowers a light lilac color. The name for the genus was given to it by Sir James Edward Smith, an English botanist and founder of the Linnaean Society in 1788. The name honors Dr. Johan Peter Westring (1753-1833), a botanist and physician to King Charles XIII of Sweden who was a student of Linnaeus. We also grow the primary species Westringia fruticosa and many cultivars of it including the variegated forms Westringia fruticosa 'Morning Light' and Westringia fruticosa 'Smokey', the low growing Westringia fruticosa Mundi and Westringia fruticosa Low Horizon, the compact gray Westringia fruticosa Gray Box, as well as the hybrids Westringia 'Wynyabbie Gem', Westringia 'Wynyabbie Highlight' and and the compact blue flowering Westringia 'Blue Gem Information on this page is based on research conducted in our nursery library, from online sources, as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens where we have observed it. We also will incorporate comments received from others and welcome getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips would aid others in growing Westringia 'Lilac Gem'.
