Agastaches or hummingbird mints/giant hyssops will bring a splash of colour and height to the garden border. They have majestic spikes of long-lasting bottle-brush flowers and scented leaves. Attractive to pollinators, these incredible perennials work exceptionally well with euphorbias, monardas, sidalceas and any plants or grasses which will allow their spiky flowers to pop through the foliage. For extra pizzaz, try mixing with crocosmias!
- Plant once all risks of frost have passed,
- Plant in fertile, well-drained soil
- Place in full sun
- Water deeply but occasionally
- Provide mulch in winter
- Agastaches are now supplied as bare-root perennials

Potential problems, pests and diseases:
Agastaches do not usually suffer from any serious pest problems. However, their leaves can be affected by powdery mildew during dry summers. Usually caused by planting in the shade or by poor air circulation, these fungal diseases appear as a white, powdery coating on the leaves. Cut off any infected material before disinfecting your scissors.
