Nepeta 'Six Hills Giant'

Plant details

Catmint is a traditional sunny border plant, large and very hardy in this outstanding variety, sometimes called Nepeta gigantea. 'Six Hills Giant' has grey-green foliage, covered all summer in masses of short spikes of lavender-like flowers which attract lots of bees. Once established, the plant is fairly drought-tolerant. The foliage is very aromatic and, when crushed or bruised, releases a strong lemony scent, hence the popularity of the plant for edging paths.

This is very easy to propagate from soft tip cuttings.


Great plant - nice and tall (although a bit lax and may need some support in windy areas) and flowers from end of May all summer long, even in my partially shady border. Have taken some soft tip cuttings which are doing well. Other plants grow through it e.g. penstemons and lysimachia 'Firecracker' and the reds and blues look really good together.
