Blue Gem is an improved seedling selection of the Australian-native “coastal rosemary” that was selected for one simple reason: it’s flowers.

In late winter/early spring, Blue Gem will be completely covered with vivid, almost fluorescent flowers.

Coastal rosemary, so named for its rosemary-like leaves, is drought tolerant, salt tolerant, has some frost tolerance and some varieties, including Blue Gem, are proving to be adapt to humid, subtropical climates of the southeastern US.

Good for home gardens and commercial landscapes alike.

Westringia are best suited to Mediterranean climates but, as mentioned, Blue Gem is showing promise for the South!
