Lavender 'Imperial Gem'

‘Imperial Gem’ is a compact evergreen English lavender with narrow, aromatic gray-green leaves and fragrant spikes of dark violet flowers. The RHS recognizes it with an Award of Garden Merit and recommends it for pollinating insects. Its tidy domed habit suits sunny borders, gravel gardens, and containers. ## Size and Placement The [RHS Imperial Gem profile](https://www.rhs.org.uk/plants/65306/lavandula-angustifolia-imperial-gem/details) gives a mature height and spread range of 4–20 inches and flowers from mid to late summer. It recommends full sun and well-drained soil; chalk, clay, loam, or sand can work when drainage is good. The RHS rates it H5 for UK conditions, which is separate from USDA hardiness zones. ## Growing Conditions This lavender tolerates drought once established, but avoid waterlogged soil, especially in winter. Give the foliage room for airflow and choose a sheltered, sunny position in colder or exposed gardens. Its evergreen foliage keeps structure in the garden outside the flowering season. ## Maintenance Deadhead after flowering and trim lightly in late summer to keep the mound tidy. Avoid autumn pruning in wet or cold regions, and never cut into old wood.
