Nepeta manchuriensis 'Manchu Blue' - 2026

Nepeta manchuriensis ‘Manchu Blue’ is a striking, tall catmint cultivar offering a rich display from late spring into summer. The plant forms an upright, bushy clump of aromatic grey-green leaves, which provide a strong textural base. Above these rise impressive spikes of bluish purple flowers, with white lips speckled with purple and inky blue calyces that make them all the more eye-catching. The blooms are generous, long-lasting, and much loved by pollinators including bees and butterflies.

This cultivar thrives in full sun, preferring well-drained soil. It is fully hardy in the UK, and though it reaches its best in good light, it tolerates average garden conditions once established. Trimming after flowering helps keep it tidy and encourages better form. Because of its height and showiness, it makes a fine focal point for mixed borders or can be planted en masse to create strong visual impact, while also contributing to wildlife value.
