Plant description
‘Litte Adder’ is great for adding height to a border, with whorls of long-lasting, tiny lavender-blue flowers arranged like a bottlebrush and pointed, aniseed-scented, fresh green leaves that are attractive to butterflies. Try it as part of a Mediterranean scheme or in a sunny, well-drained border among ornamental grasses. Hyssops often need replacing every few years, especially after a cold or wet winter but can be easily propagated by cuttings.

How to care for Agastache rugosa Little Adder:
Don't cut back the faded flower-stems until early spring, as they provide interest in the winter months. Lift and divide congested clumps in spring.
Please note:
This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
