Santolina, both the green and gray varieties, are extremely versatile in the landscape.
They are drought resistant, but will adapt to just about every climate. This plant is also known as “lavender cotton” and is actually a perennial herb. It can be used as a groundcover or upright ornamental. Many gardeners will lop off the flower heads because they want only the attractive foliage. Neither variety of santolina has any serious issues with pests or disease.
Santolina typically grows from 12 to 18 inches, but looks best if it is clipped to a height of about a foot.
The green variety grows faster than its gray cousin and is more compact. A single plant can spread to about four feet and form a rather uneven, but still quite attractive mound.
As the branches grow longer, if left unclipped, they will droop to touch the ground and take root wherever they touch the soil.
If not clipped back, both the green and gray varieties will produce yellow, button-like flowers in Mid-June or so.
There will be stems that shoot up several inches above the foliage. The clusters of flowers will be at the tops of these stems, each bloom ½” to 3/4” across. The blooms are quite showy, and pollinators of all kinds love them.
Adding some to your garden spaces is a good idea!
Now, get out there and grow something!
