Santolina rosmarinifolia (Green Santolina) - A neat rounded aromatic evergreen shrub that typically grows 1 to 2 feet tall and as wide but when happy can get a little larger. It has deep green narrow leaves. The pale yellow rounded composite flowers appear in the mid to late spring. Plant in full sun in a well-drained soil and irrigate only occasionally. It is drought tolerant and hardy to 0 °F. Though often used in knot gardens and trimmed to keep low, consideration should be made to its requirements of good drainage and careful irrigation practices. Overwatering of this plant or plantings in poor draining soils often result in root rot, but a well-established plant thrives with little to no supplemental irrigation and be very attractive in the garden. Shear lightly in early spring to keep dense and dead head spent flowers.
