Santolina

Santolina

Santolina chamaecyparissus ( Lavender Cotton )
Also called Santolina incana. A rapid growing, small, evergreen shrub, reaching a maximum size of 3.5 x 6.7 feet but averaging closer to 1.7 x 3.3 feet. Some records include: 5 years - 1.7 x 6.7 feet. It is native from southern Spain thru southern France to Greece. It can be clipped and used as edging or for a low hedge.
The aromatic bright silvery-gray, thread-like leaves, up to 2.4 x 0.15 ( usually under 1.5 ) inches in size, are feathery and soft. The young foliage is almost white.
The foliage may become deciduous in cold climates.
The abundant, yellow, button flowers, up to 0.7 inches wide, are borne on new growth during early summer. They are usually clipped off.
Hardy zones 7 to 10 ( 6 on very protected sites ) in full sun on very well drained soil. Unlike in the west; it is not summer hardy south of zone 7 in the east due to hot humid summers causing fungal problems.
Shear off old blooms during late summer, shearing at other times may disrupt blooming. Tolerant of heat, severe drought, humidity, poor soil, salt, wind and fire. Deer and rabbit resistant. It is often clipped back to 6 inches in height during early spring to encourage vigorous dense habit. Can be cut to ground every 3 years and will regenerate quickly. Propagation is from seed or rooting cuttings in sand.
