Santolina chamaecyparissus (Gray Lavender Cotton) - A low, dense, long lived evergreen shrub that grows to 2 feet tall and 3-4 feet wide. The hairy gray aromatic pinnately-lobed narrow 1 inch long leaves with tiny leaflets densely clothe the hairy shoots. Solitary yellow button flowers bloom on 6 inch tall stalks during the late spring and summer. Plant in full sun to part day sun and irrigate very little if at all once established - truly a drought tolerant plant! Hardy to 0 °F or below and useful in USDA Zones 5b to 10. Tolerates seaside conditions and is resistant to animal predation. This plant does particularly well in coastal California garden with little or no supplemental water - in situations such as this a flowing carpet effect of foliage, under 1 foot tall, can develop. A great plant for a formal edging or allowed to flow for an informal look.
