Agastache (Giant Hyssop, Korean Mint)
A lovely group of plants that are perfect for a sunny border, the Giant Hyssops have attractive aromatic foliage and gorgeous vertical spikes of bottlebrush-like flowers over a very long period from June through until October. The flowers are always popular with bees and butterflies and the seedheads that follow provide a feast for the birds, ficnhes in particular.
Agastache are useful for adding some vertical accent into mixed borders, they mix especially well with ornamental grasses and are great for a mediterranean themed area. Having such tactile flowers paired with aromatic foliage, these are just the thing for a sensory garden. The leaves are edible and good for pepping up salads or infusing to make tea, and so Agastache would not be out of place as a colourful addition to your herb garden too.
As a rough guide planting Agastache as ground cover – 4 plants per square metre is adequate with a little patience, 6 will give better coverage and 9-12 will make a weed supressing carpet very quickly.
