Common Name:
Giant Hyssop 'Blue Boa'
Description:
Agastache x 'Blue Boa' is a stunning, long-flowering perennial known for its bold, deep violet-blue flower spikes that rise above fragrant, dark green foliage. Blooming from late spring through autumn, this variety attracts bees, butterflies, and other pollinators, making it an excellent choice for wildlife-friendly gardens. 'Blue Boa' thrives in full sun and well-drained soil, displaying excellent heat and drought tolerance once established. Its upright, bushy habit makes it ideal for garden borders, mixed perennial beds, and large containers. Deadheading spent flowers will encourage continuous blooming, while its scented foliage adds an extra sensory delight to the garden.
