Agastache rugosa Liquorice Blue
Agastache rugosa Liquorice Blue is commonly known as Korean Mint. It is a hardy perennial with aromatic foliage and spikes of hooded, blue-lilac blooms. A. 'Liquorice Blue' is a newer form of agastache, carrying an impressive amount of flowering spikes to 60 cm in height, which are sturdy and upright - more so than other varieties, meaning they do not require staking. The foliage is a toothed, dark green arrow-shaped leaf, which when brushed against or crushed emits a sweet liquorice perfume.
Agastache rugosa Liquorice Blue prefers well-drained soil and full sun but will tolerate most soil types as long as not too wet. Cut back after first flowering on fertile soils to prevent the plant becoming leggy and flopping.
A great perennial to attract bees and butterflies. If the flower heads are left on over winter, the birds love the seeds. Suitable for cut flowers.
