Catmint Six Hill Giant
This upright billowing Catmint is ideal when combined with old roses, or amongst other dry tolerant perennials. From spring, towering spires of soft mauve flowers are produced over grey green foliage, and adored by beneficial bees and beautiful butterflies. As the flowers fade around January, cut the entire clump back to the ground for a second flowering throughout autumn.
How to grow
Easy to grow. Cut back before flowering to maintain a compact shape and then again after flowering to encourage a second bloom.
