Buddleja glomerata ‘Silver Service’ is a distinctive, evergreen to semi-evergreen shrub valued for its soft silver-grey foliage and unusual, rounded clusters of warm yellow flowers. Blooming in late spring to early summer, the small, honey-scented flowers are held in tight heads rather than the long panicles typical of Buddleja davidii, giving the plant a refined and architectural appearance. The narrow, felted leaves provide year-round texture and colour, making this variety especially effective in sunny borders, Mediterranean-style gardens, and coastal or drought-tolerant planting schemes. More restrained and elegant than many buddlejas, it offers subtle colour and strong foliage interest with minimal maintenance.
