Botanical Name

NEPETA 'Six Hills Giant'

Plant Common Name

Hybrid Catmint, Six Hills Giant Catmint

General Description

If it’s a tough, drought-tolerant, everblooming perennial you seek, then look no further. The hybrid 'Six Hills Giant' offers loose, upright clusters of violet-blue flowers all summer. These appear on large plants with distinctly fragrant foliage.

The big mounded plants of 'Six Hills Giant' have fuzzy, heart-shaped leaves with scalloped edges that are medium to grey-green. The drier the growing conditions, the greyer the foliage. In summer, it produces tall, upright clusters of small, tubular, violet-blue flowers. These attract bees and butterflies and will continue to bloom most heavily if regularly deadheaded or lightly sheared after the first flush of blooms.

Full sun and average to fertile soil with sharp drainage are best for growing catmint. Wet soils are especially detrimental to the health of these plants as they can lead to root and stem rot. This is a carefree and easy perennial for sunny spots. It is ideal for sunny garden edges, rock gardens, and containers. The plants look great when planted in masses with other tough perennials and grasses for sun. Nepeta is also deer resistant and may lightly self-sow.
