Description How to Grow More Info Delivery Reviews Video
Nepeta 'Six Hills Giant' is one of the most widely grown Catmints. This popular hardy perennial bears its lilac-blue flower spikes above mounds of silvery-green foliage from early summer onwards. The nectar rich blooms are always attractive to bees and of course, cats adore the aromatic foliage. Plant this tall variety in generous swathes, letting it spill from borders and soften path edges. A cottage garden favourite and a lovely cut flower too. Height: 90cm (35"). Spread: 60cm (24").

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.
