— Westringia fruticosa ‘WES04’ Grey Box™ PPAF —
A true dwarf coastal rosemary selection that has a natural “Box” shape and beautiful gray-green foliage which makes this Westringia far different than any other we have seen. Perfect for a hedge or group planting in pocket gardens and home gardens, yet tough enough for commercial applications as well! Grey Box seems to work well in both arid and humid Zones 9-11 climates. So while Westringia are best suited to Mediterranean climates, Grey Box has continued to perform very well in subtropical climates, provided it is planted in a raised and free-draining soil and is watered infrequently (and best when irrigated via drip irrigation).
