Nepeta Six Hill Giant

Common Name:
Six Hills Giant Catmint

Description:
Nepeta × faassenii 'Six Hills Giant' is a robust, clump-forming perennial renowned for its aromatic grey-green foliage and abundant lavender-blue flower spikes. Blooming profusely from late spring through autumn, this cultivar attracts bees, butterflies, and other pollinators, making it an excellent choice for wildlife-friendly gardens. Its sprawling habit and long flowering period make it ideal for borders, cottage gardens, and as a companion to roses. In Melbourne's climate, 'Six Hills Giant' thrives in full sun to part shade and prefers well-drained soils. Regular deadheading encourages continuous blooming, and cutting back after flowering helps maintain a compact form. Its drought tolerance and low maintenance requirements make it a valuable addition to water-wise landscapes.
