Nepeta manchuriensis Manchu Blue is a large perennial, vigorous and robust, with a bushy habit forming a beautiful clump. It displays a beautiful velvety and aromatic foliage, with wide leaves of a beautiful fresh green. From May to July, it showcases long spikes bearing large bluish-purple flowers.
Nepetas, also known as Catnip, Catmint or even Catnip Mint, belong to the Lamiaceae family. The species Nepeta manchuriensis is native to Manchuria and Siberia. The Manchu Blue variety is a large herbaceous perennial, vigorous and robust, with a bushy and dense habit, measuring 70 to 100 cm (28 to 39in) in height with a width of 60 cm (24in). This cultivar, with fast growth, has deciduous aromatic foliage consisting of wide, velvety, ovate, dentate, bright green leaves. From May to July, it showcases numerous flowering stems bearing large bluish-purple flowers. Very floriferous and attractive to pollinating insects, it is highly ornamental.
Nepetas are very easy and trouble-free perennials, that are robust and fast-growing. They are essential in the garden for their bushy form, aromatic foliage, and relentless flowering throughout the summer. This catmint, with its long-lasting bluish-purple flowering, is a highly ornamental plant that will be valuable in the garden, whether planted in full sun or partial shade, in a rockery, on a slope, among a perennial border, or even in a scree garden. It is well suited for container cultivation on a patio or balcony. Perfectly hardy, this species appreciates sunny locations and well-drained soil. Its long flowering stems make it an excellent cut flower for creating beautiful country bouquets. The bluish-purple colour of its flowers will beautifully complement the yellow or orange flowers of summer perennials such as Daylilies, Kniphofias, and Rudbeckias, creating stunning contrasts. It will also undoubtedly and beautifully blend with pastel or darker coloured perennials, such as certain Phlox, purple Rudbeckias, Oriental Poppies, Japanese Anemones, and Knautias. It will also have a striking effect at the base of shrub and climbing roses, where it will conceal the often bare and unsightly base.

Botanical data
Nepeta manchuriensis Manchu Blue is a vigorous perennial, very easy to grow and perfectly hardy, at least down to -15°C (5°F). It appreciates a sunny position or light shade, as well as ordinary soil, even sandy, rocky and poor, moist to dry, well-drained, especially in winter. In heavy soils, it will be necessary, during planting, to add gravel and sand to improve drainage. Adapting well to drought, watering should only be done if the plant shows obvious signs of thirst. Planting should preferably be done in spring, so that the roots are well developed before the winter cold. It is advisable to let the clump dry out all winter, to protect the stump from the cold. Cut back severely in early spring, before the new foliage starts to grow. Throughout flowering, remove faded flower spikes to encourage continuous flower production. It is also possible, during summer, to cut back the faded inflorescences with shears to a height of 20 cm (8in), which will make the plant more compact and extend its flowering until autumn, or even until frost. Multiplication can be done by dividing clumps in spring. It should also be noted that this species readily naturalises in the garden through self-seeding, as long as a few faded spikes are left on the plant to produce seeds. While young shoots of Nepetas are highly disease resistant, they can sometimes be attacked by slugs, and the foliage may develop powdery mildew in dry summers.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
