Description 

Ajuga pyramidalis ‘Metallica Crispa’ is a striking, compact groundcover with deep metallic‑purple, crinkled foliage and short spikes of vivid blue flowers in spring. Unlike the more common Ajuga reptans, this species forms tight, sculptural rosettes that hold their colour beautifully throughout the year.

Perfect for moist soils, pond edges, damp borders, and shaded planting schemes, this hardy perennial adds texture, richness, and contrast wherever it’s used. It’s especially effective at softening hard edges and filling gaps between taller marginals.
