Six Hills Giant Catmint
Botanical Name: Nepeta x racemosa

Catmint ‘Six Hills Giant’ is a large and upright herbaceous plant, growing to 70cm by 100 cm wide. The branches spread out creating a mound, topped with mauve coloured flower stalks over summer. The grey –green foliage is aromatic and provides a nice backdrop to the tall flower stalks. The flowers are small, but numerous and appear to be shaped like trumpets. They appear in spring and summer, providing a food source for bees and butterflies. A second round of flowering can be encouraged, creating a long blooming season. This catmint is said to be the longest flowering variety.

This plant requires space to grow properly and can be a very showy plant with its attractive flower stalks. If several are planted together they will form a large and dense groundcover. The plant has a branching habit that cause the branches to lean out from the centre, so it may be useful to use a ring support or to tie them back or together. It is a good partner to roses and suits cottage gardens.

The parent plants are Nepeta racemosa and Nepeta nepitella, but it may also be listed with the botanical name Nepeta mussinii or Nepeta faassenii. It may be necessary to check that the plant is a large growing catmint to be sure you have the correct plant given the variety of names or labels.

Growing Conditions

This vigorous catmint is considered to be drought tolerant and quite hardy. It will tolerate part shade, but full sun is preferred. Some moisture or damp soil is tolerated, unlike most catmints. However, all soil types must be well drained and dry soil is quite acceptable. The soil does not need to be especially fertile or enriched. If the ground or weather is too damp or the soil to rich the plant may tend towards droopiness. ‘Six Hills Giant’ may be semi-deciduous depending upon the area.

Flowering is in spring and summer, but the plant may be cut back after the summer flowering to encourage a second blooming period in autumn. ‘Six Hills Giant’ is a hybrid plant so it does not self seed. It may be propagated by division or by taking softwood cuttings. Dividing the plant every few years also helps to revitalise the plant. Although the plant may spread a little, this is due to branching rather than underground rhizome spread.
