Ajuga genevensis, known as Blue Bugle or Geneva Bugle, is a clump-forming herbaceous perennial native to dry grasslands and rocky slopes across Europe. Unlike its more common relative Ajuga reptans, it produces no stolons and stays in a contained rosette, making it far easier to site without concern about spread. Upright, dense clusters of vivid blue flowers appear in late spring above coarse, hairy foliage.
Because it forms tidy clumps rather than running mats, A. genevensis suits rock gardens, dry borders, and pathway edges where a spreading plant would be unwanted. It tolerates drought and lean, stony soils better than A. reptans and performs well in full sun given adequate moisture during establishment. Divide clumps every two to three years to maintain vigor. Sharp drainage is essential; prolonged wet or waterlogged conditions invite crown rot.
