Agastache rugosa
Agastache rugosa — commonly known as Korean mint or anise hyssop — is one of the most rewarding drought-tolerant perennials you can grow. A member of the Lamiaceae family and close relative of lavender and sage, it produces tall, architectural blue-violet flower spikes from July through to October, drawing bees, bumblebees and butterflies in extraordinary numbers. Hardy to −25 °C in well-drained soil, it thrives in full sun with minimal care, making it an ideal choice for xeriscaping, gravel gardens and low-maintenance borders.
The stems are well-branched, the foliage is coarsely toother and spicy-scented, and the flowers themselves carry a faint spice — making them unusual and delicious as a garnish in salads.
In sunny climates with free-draining, poor soil, Agastache thrives where other perennials struggle. Its flowering period stretches from summer to the first frosts, it requires little maintenance, attracts heaps of pollinators, and is largely disease-resistant provided there is good drainage.
