Nursery contributed plant descriptions

A soft, evergreen palette of silky-haired, gray-green leaves and trailing, fuzzy silver stems set off the glistening, uplifted racemes of creamy blooms. Each two-lipped blossom is accented with a pale yellow throat striped in lilac. Exhibiting a fortitude for dry conditions and a small mounding presence, this pretty bushlet is ideally suited to the rockery or along a path where it soothes rough edges, and can be accompanied by Diascia 'Coral Canyon' and Nepeta 'Select Blue'.
Another one of those fuzzy gray leaved, low growing, perennial snapdragons for the rock garden. A bit smaller and more compact than A. molle, but otherwise virtually identical. Hardy for us so far, but yet to experience a real cold winter. Zone 6, at least
