Ajuga reptans 'Catlin's Giant' (Bugleweed) is a dense, spreading perennial offering bronze-green foliage and blue spikes.
Complete Plant Information
Overview
Ajuga reptans ‘Catlin’s Giant’ is a highly valued herbaceous perennial known for its vigorous, mat-forming habit, making it an exceptional ground cover solution. This specific cultivar of Bugleweed distinguishes itself with striking bronze-green foliage that remains attractive throughout the growing season. When it flowers in spring, whorls of blue spikes rise above the dense carpet of leaves, providing a lovely contrast.
Gardeners appreciate this plant for its speed of coverage and its low-maintenance nature once established. Ajuga reptans ‘Catlin’s Giant’ spreads primarily by stolons, quickly filling in difficult or shady areas where turf grass struggles. Utilizing Bugleweed effectively smothers weeds, creating a tidy, attractive, and functional landscape layer.
For best results, ensure the planting location receives adequate sun exposure—though it tolerates shade, part-sun reveals the best foliage color. Proper air circulation is key, especially in humid climates, to prevent potential fungal issues common to this spreading perennial.

How to Grow
Planting Ajuga reptans ‘Catlin’s Giant’ is best done in the spring or fall. It thrives in average, medium-moisture, well-drained soils. While it tolerates moderately dry conditions, Bugleweed prefers moist, humus-rich soil for optimal performance. For prompt, dense coverage, space plants between 6 to 9 inches apart, allowing their stolons to connect quickly.
Care for this low-growing Bugleweed is generally minimal. Maintain medium moisture levels, especially during establishment, though Ajuga reptans ‘Catlin’s Giant’ is adaptable. Fertilization is rarely necessary if the soil is reasonably fertile. In hot, humid regions, ensure good air movement around plants to mitigate risks of crown rot.
Regular maintenance involves light cleanup. If the foliage declines after flowering, prune the plants back to the ground to encourage fresh growth. For very large established patches, mowing on a high setting can effectively remove spent flower spikes and tidy the aesthetic appearance. Remember to divide overcrowded clumps periodically to maintain vigor.
Landscape Uses
The primary utility of Ajuga reptans ‘Catlin’s Giant’ lies in its role as a superior ground cover. It excels at filling vast, shady expanses where traditional lawn grasses fail, such as underneath mature trees or beneath large shrubs. This Bugleweed is also excellent for stabilizing banks and slopes due to its dense, creeping root structure.
Designers frequently utilize this perennial around borders or as an alternative lawn in small, intricate garden spaces. Consider planting spring bulbs, like snowdrops, directly into the Ajuga layer; as the bulbs fade, the robust Bugleweed foliage remains as an attractive green-bronze mat. A crucial consideration is to avoid planting it adjacent to established lawns, as the aggressive stoloniferous nature of Ajuga reptans ‘Catlin’s Giant’ will quickly lead to invasion.

Potential Problems
Crown rot represents the most significant potential issue for this Bugleweed, especially when planted in heavy, wet soils common in the humid Deep South. To prevent this, always ensure excellent drainage and provide ample air circulation around the crowns. If clumps become too dense or show signs of decline, division is necessary as part of your regular maintenance schedule. Gardeners should also be careful when planting near lawns or delicate perennial beds, as the rapidly creeping habit of Ajuga reptans ‘Catlin’s Giant’ can make removal difficult once established.

Its bronze-green foliage and reliable showy blue blooms ensure year-round visual interest and effective weed suppression. Before planting, confirm your location falls within USDA Zones 4-8 and ensure soils drain adequately to enjoy this fantastic Bugleweed for years to come.
Companion Planting Under Trees
Since Ajuga reptans ‘Catlin’s Giant’ thrives in dry shade once established—a condition common under mature trees—it pairs well with other shade-tolerant, clump-forming, or finely textured ground covers. Consider pairing it with Hellebores (Lenten Rose) for varied winter interest, or with hardy shade ferns like Dryopteris species. This combination creates a layered woodland effect that minimizes competition for resources while maintaining aesthetic appeal throughout the seasons.
Propagation Tips
Propagation of this lovely Bugleweed is exceptionally straightforward due to its natural spreading habit. The quickest method is division; simply lift a section of the established mat, ensuring it has runners (stolons) attached, and replant these divisions directly into the desired location. This can be done anytime the soil is workable, though spring division ensures the best root establishment before the heat of summer. This ease of division makes it perfect for quickly increasing stock for large landscaping projects.
