Nepeta 'Six Hills Giant' is a vigorous, larger-growing catmint with aromatic grey-green leaves and generous spikes of violet-blue flowers. It fills out quickly to create a soft, billowing border plant.
- Violet-blue flower spikes through summer
- Aromatic grey-green leaves
- Pack of 24 young plants in 11cm pots, 15-25cm tall as supplied
- A larger, bolder habit than most catmints
- Prefers full sun and free-draining soil
- Popular with bees and butterflies
Plant in a sunny position with good drainage, leaving enough room for it to spread, about 50cm between plants. Cut back hard after the main flush to promote tidy regrowth and further flowers. It looks good beside salvias, echinacea and ornamental grasses.
Supplied as young plants in growing pots, shipped directly from our partner growers. Plants are living products, so size and shape can vary slightly from the photo.
