A favourite of the Heronswood border, Agastache 'Blue Fortune' is as reliable as it is beautiful. Its sublime powder-blue tubular flower spikes provide a profusion of colour for many months, perfectly complementing pastel coloured perennials and straw coloured grasses late into summer. Adored by bees, birds and insects, also known as Hummingbird Mint or Hyssop, Agastaches are a must have to bring biodiversity and pollinators to the garden. Fabulously fragrant, anise scented foliage is an added bonus - plant beside a path where it can be brushed up against and use the leaves for steeping in teas. Suits naturalistic style planting schemes, cottage or coastal gardens.
