Anise Hyssop Plug Plant Agastache foeniculum
Common names include blue hyssop and giant blue hyssop.
An aromatic perennial herb with tall, elegant spikes of deep lilac-purple flowers from mid-summer into early autumn. Loved by bees, butterflies, and hoverflies, it’s a superb pollinator plant that brings both beauty and biodiversity to gardens and meadows. The foliage releases a sweet, fennel-anise aroma when brushed, and the leaves and flowers are edible, adding a subtle liquorice flavour to teas, salads, and desserts.
Thriving in full sun and well-drained soils, this drought-tolerant species is ideal for wildlife-friendly planting, herb borders, and naturalistic schemes. It’s a resilient and versatile plant that pairs well with other late-summer perennials.
Our strong, healthy plug plants are grown in 40cc cell trays and ready to plant directly into their final position.
Sourced from UK-grown stock, these plugs are perfect for establishing this attractive and useful herb where seed germination may be unreliable.
We recommend planting 5–7 plugs per square metre in groups for a natural effect.
