Fabiana imbricata violacea
At first glance, this plant looks a lot like a heather, but it is actually in the same family as potatoes. The foliage is finely textured & soft. It has profuse, lavender, tubular flowers in Spring/Summer. Fabiana can grow to 3’ high but in youth it tends to sprawl a bit. It looks good spilling over a low wall. Can be grown in a seaside gardens. I’ve seen a large one up North growing in a garden right on a sea cliff, so I know it can take sea spray & wind. Best with good drainage.
