We are always on the lookout for combinations of plants that might work together in particular situations. This combination of Grevillea lanigera with Tuecrium fruticans has got potential.
Both plants have wonderful silver foliage. This tells us that they both enjoy a very sunny situation and can probably tolerate dry conditions. Tuecrium is an excellent choice for clipping into topiary, becoming very dense with repeated tip pruning. Grevillea lanigera is prostrate and provides a weed suppressing groundcover. Both can be easily propagated.
A combination of massed Teucrium shapes, sitting in a broad base of Grevillea lanigera, would work on a hot sunny bank. And birds and insects will enjoy the flowers. So this combo will end up on one of the large steeps banks flanking the wine cellar in The Main Courtyard.
