Ajuga ‘Catlin’s Giant’ is a bold and striking cold-hardy variety of the popular Ajuga reptans, known for its purplish-bronze leaves and beautiful trumpet-shaped blooms that resemble a bugle. This herbaceous perennial is prized for its fast-growing, low-maintenance nature and ability to thrive in a variety of conditions. It is an excellent choice for gardeners seeking to add texture and color to shaded or partially sunny areas.
Ajuga ‘Catlin’s Giant’ has gained popularity due to its oversized groundcover and vibrant purple flower spikes. Unlike smaller varieties, this cultivar makes a dramatic statement in landscapes while maintaining all the benefits of Ajuga, including erosion control and weed suppression. It is also known as Catlin's giant bugleweed, or Ajuga reptans ‘Catlins Giant’.
This robust ground cover typically grows 8 inches tall. It spreads aggressively, forming a dense mat that can cover 3 feet wide, making it ideal for filling large areas in gardens.
The defining feature of Ajuga ‘Catlin’s Giant’ is its large, glossy, bronze-tinged leaves, which are much larger than those of other Ajuga varieties.
These leaves create a stunning carpet of foliage year-round. In spring and early summer, it produces spikes of deep purple to blue-violet flowers that rise above the dense rosette, attracting pollinators such as bees and butterflies.
When it comes to care, it thrives in partial to full shade but can tolerate some morning sun. It prefers well-draining soil enriched with organic matter, although it adapts to various soil types. Regular watering is necessary during establishment, but once mature, it is relatively drought-tolerant.

When grown indoors, maintain a temperature range of 60–75°F and provide bright, indirect light.
For outdoor cultivation, it is hardy in USDA Zones 4–9 and benefits from occasional pruning to remove dead leaves and spent flower spikes.
Fertilize your Bugleweed Catlins giant once a year in early spring with a balanced, slow-release NPK fertilizer with an equal ratio of 5-10-5 to promote vigorous growth.
Ajuga ‘Catlin’s Giant’ can easily propagate through division or by separating runners. In early spring or fall, dig up a healthy clump and divide it into smaller sections, ensuring each has roots attached. Replant immediately in the desired location, water thoroughly, and mulch to retain moisture. Runners can also be pinned into the soil to root naturally.
According to the ASPCA, Ajuga species, including ‘Catlin’s Giant,’ are non-toxic to humans, dogs, cats, and horses. This makes it a pet-friendly groundcover option for gardens, offering peace of mind for pet owners.
Overall, the Ajuga reptans ‘Catlin’s Giant’ is a versatile and visually striking plant that adds year-round interest to gardens. Its dramatic foliage, vibrant flowers, and low-maintenance care make it a standout ground cover for shaded and partially sunny areas. Whether used to suppress weeds, attract pollinators, or enhance landscapes with its lush appearance, this cultivar proves to be an invaluable addition to any garden. Its non-toxic nature and adaptability ensure it remains a favorite among gardeners of all skill levels.
