Buy Nepeta 'Six Hils Giant' catnip: A hardy catmint with lavender flowers

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun
  • Soil: moist, well-drained soil
  • Rate of growth: fast-growing
  • Flowering period: June to July
  • Hardiness: fully hardy

    A vigorous catmint with small, tubular, lavender-blue flowers held in clusters of upright stems from June to July and attractive, aromatic, light grey-green foliage. This tall perennial will form a dense mound that looks wonderful in the middle of a sunny border alongside other blue or silver-leaved plants. Fresh or dried, the leaves make a refreshing and therapeutic tea which is high in vitamin C and has traditionally been used to treat such conditions as nervousness, insomnia, hyperactivity, colds and fevers. The flowers are highly attractive to bees, and of course, the foliage to cats, who will go mad for it. To prevent them from completely flattening it, insert several twiggy sticks into the centre of the plant.

    Garden care: Cut back after flowering has finished to keep the plant compact. Lift and divide large clumps in spring, replanting divided specimens with lots of well-rotted organic matter. If powdery mildew becomes a problem prune out the affected areas.

A useful and desirable plant.


Bought for my cat, and for delicious, clean, fragrance, different from ordinary mint. Seemed to deter flying insects.




Would definitely buy again!


Really lovely healthy plants that have thrived, well packaged, fast delivery and would use again.




Not a fast grower


I planted this beside a seating area and the bees love it. While it's established well, it hasn't grown as fast as other varieties of catmint in my garden.




I would buy again


Excellent variety tall and vigorous ,so had to move some plants .

Best value ever!


Love this plant as I've a brand new garden and it's self seeded itself in the gravel and it looks great! Beautiful bunches of purple with bees all around, heaven!




Loved by bees


Nepeta 'Six Hills Giant' lives up to its name as the plants can get very large just in one season. Suggest you do the 'Chelsea Chop' and cut the foliage right back in late June / early July after first flowering to keep a neat appearance for the rest of the season. That said, nepeta is an English garden classic, beloved of bees and butterflies and with a long flowering period. The silver grey foliage provides a soft contrast next to paving stones and the long flower spikes waft nicely in a summer breeze. Nepeta 'faassenii' is a better variety if you want something smaller and more clump shaped for underplanting, say, under roses.

Excellent healthy plants


Purchased the 6 pack and as my garden is smallish I planted them in builders rubbble buckets (cheap from B&Q). First season they reached full size and were fantastic for attracting bees. Other than cut them back at end of season and soak them in miraclegro from time to time they remain fantastically healthy and no effort at all to maintain.






Good healthy plants grew well and covered the boarder well, well packed and in excellent condition when they arrived.




Very long flowering


Really flourished...ready for splitting

The Chelsea Chop (and other methods of extending the flowering season)

Many gardeners who are happy, even gung-ho, with the secateurs when pruning shrubs and climbers are surprisingly reluctant to take the shears to herbaceous perennials. Maybe this is because it just doesn't seem quite right to be cutting back all that new

Planting companions for roses
