Catmint is a large genus of about 250 species found in most temperate and cold regions of North hemisphere. Apart from a very few annuals it is a perennial with aromatic foliage and mostly violet flowers, seldom white, and uniquely yellow. Commonly cultivated species are n.nervosa, n.sibirica, n. x faassenii, and further hybrids. Not all species produce leaves whose scent is attractive to cats.

Six Hills Giant is a popular catmint variety of vigorous growth. It grows up to 90 cm tall and wide and looks like a small shrub. From June open small, pale violet flowers along and atop slender stems. Mint-scented leaves (and possibly the whole plant) look very similar to perovskia, they are small, ovate, scalloped, and gently serrated at margins. Thanks to extremely long flowering period it makes a great feature in summer gardens, on patios and balconies, and combined with spring flowering shrubs or perennials. If the plant gets leggy or unsightly in midsummer cut it by half and it will emerge with new, shorter but stronger stems that will produce flowers until early autumn.

This variety was named after a giant from Stevenage in Hertfordshire, England. The legend says that for fun a giant used to throw (his) handfuls of earth at passers-by. He missed six times hence the six piles/hills (six Round Barrows from the Bronze Age). The seventh time he did not look and threw over his shoulder. He hit a spire of the nearby church in Graveley that is allegedly askew until today. Funny story, isn't it? Fancy a giant throwing earth at village people who very likely kept stalking and annoying him for so long that he decided to act. Just one thing is wrong - if the hills are from the Bronze Age (3000-1200 years BC), and the world's first church debris were found in Megidd in Israel and are dated 3rd-4th century AD, the legend remains a bedtime story just like the one about the Loch Ness Monster.

Catmint is not too picky about soil type, however, it is not as drought tolerant as some landscape designers think. Especially tall growing species should never dry out completely on hottest days of summer. And on the contrary over-fertilized and over-watered plants may become leggy. Use common garden soil that will drain freely, and irrigate the plant only when needed. Catmint is suitable for full sun and part shade. Very hardy to about -37°C (USDA zone 3), and suitable for outdoor pots.
