Catmints add a lovely, soft, floppy, gentle touch to cottage gardens. Nepeta gigantea 'Six Hills Giant' has grey-green foliage, which is 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. It's used as a caterpillar foodplant for the pretty mint moth, Pyrausta aurata. Light, well-drained soil is the key to success. After the first burst of flowers, shear over the growth to get a second crop of leaves and flowers. Other catmints are available in pale and darker blues.
Grow Nepeta gigantea 'Six Hills Giant' in well-drained soil in full sun. ift and divide congested clumps in spring.

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.
