Why Choose Catlin’s Giant?
Dramatic Foliage
One of the standout features of ‘Catlin’s Giant’ is its large, glossy, deep burgundy to bronze-purple leaves that form a dense mat over time. The foliage alone is enough to bring rich color and texture to shady beds and understorey plantings.
Spikes of Electric Blue
In spring and early summer, the plant sends up short spikes of vibrant blue-violet flowers, rising above the foliage like a small floral display. These blooms attract bees and pollinators, making it not just ornamental, but beneficial to your garden’s ecosystem.
Weed Suppressant
Thanks to its vigorous, spreading habit, Catlin’s Giant quickly forms a dense carpet that helps suppress weeds. It’s perfect for filling in awkward areas where other plants struggle.
Shade Tolerant
Few plants offer such visual impact in full to part shade. This makes Ajuga ideal for planting under trees, between shrubs, or in shaded borders where sun-loving groundcovers won’t thrive.
Garden Uses
Underplanting for trees and shrubs
Groundcover for shaded garden beds or slopes
Soft edging for woodland paths or stone walkways
Mixed borders with ferns, hostas, or heuchera
Container gardens and spillover planting
Growing & Maintenance Tips
Soil: Prefers moist, humus-rich, well-drained soil but is adaptable to a variety of conditions. Avoid soggy spots.
Watering: Keep well-watered while establishing. Once mature, it’s fairly drought-tolerant in shaded areas.
Spacing: Space plants about 30–45 cm apart for quick coverage.
Pruning: After flowering, you can trim back flower spikes to tidy up the look. Divide clumps every few years to rejuvenate and control spread.
Caution: While not considered invasive, Ajuga spreads readily—avoid planting too close to lawn edges or delicate borders.
Design Tip
Contrast Catlin’s Giant with lime green foliage (like Carex or golden Hosta) or soft silvers (such as Brunnera or lamb’s ear) to highlight its rich hues. Mass plant for a dramatic carpet effect or tuck into shady corners for a bold pop of texture.
Ajuga ‘Catlin’s Giant’ is proof that groundcovers don’t have to be boring. With bold foliage, electric blooms, and a low-maintenance growth habit, it brings both function and flair to shaded gardens. Whether you’re refreshing an underused space or building out a woodland design, this bugleweed earns its place in any well-considered landscape.
