Nepeta faassenii ‘Grol’ is a compact and bushy perennial cultivar of garden catmint, known for its rich flowering and upright habit. This cultivar produces abundant blue-lilac flowers from June to September, attracting pollinators such as bees and butterflies. The aromatic grey-green foliage adds sensory interest to the garden. ‘Grol’ is particularly valued for its resilience and low-maintenance nature, thriving in well-drained soils and full sun to partial shade. Once established, it is drought-tolerant and can withstand dry conditions, making it suitable for low-water gardens. Regular deadheading can encourage prolonged blooming, and cutting back after flowering may promote a second flush.

Its compact growth habit makes it ideal for borders, rockeries, or as a ground cover. ‘Grol’ is also deer-resistant, adding to its appeal in various garden settings.
