To truly appreciate green santolina, you need to brush your hand lightly and slowly across the flowerheads. The rubber-eraser-like capitula on the upright stems will spring back from the disturbance, hitting the side of your hand.
Native to Mediterranean Europe, Santolina rosmarinifolia subsp. rosmarinifolia is used in gardens as a low-maintenance groundcover. It has a reputation for being drought-resistant, which makes it an ideal waterwise plant in areas where it is hardy.
