Agastache foeniculum, (Blue Boa; Anise Hyssop)
A fabulous plant for the flower or herb garden, with lovely bushy clumps of soft, green/purple-tinted aromatic foliage, and multiple branched spikes of lavender blue flowers in summer. Full sun to part shade in average soil with good drainage is best. Wonderful bee and butterfly plant, and the scented foliage has many culinary uses as well. Hardy perennial, usually winter dormant in cold areas. Flowering size 60-90cm high x 40-60cm wide. 1 litre pot.
