Description
Lavandula angustifolia ‘Betty’s Blue’or LAVENDER ‘Betty’s Blue’ is a compact, bushy cultivar of English lavender growing upto 90cm tall with a 90cm spread & is known for its intensely rich violet-blue flower spikes and tidy, rounded habit. Bred for both ornamental and practical appeal, this variety offers a robust midsummer display with a single, concentrated flush of blooms that stand upright and resist flopping—making it ideal for formal borders, low hedging, and container planting.
The foliage is evergreen in mild climates, with narrow, aromatic grey-green leaves that provide year-round texture and fragrance. In summer, the plant erupts with dense, fragrant flower spikes that are highly attractive to bees, butterflies, and other pollinators. The scent is classic lavender – sweet, clean, and calming—making ‘Betty’s Blue’ a favourite for sensory gardens, dried arrangements, and herbal use.
