Agastache Foeniculum Seeds - Herbal Plant

Agastache foeniculum, commonly known as anise hyssop, is a perennial herbaceous plant in the mint family valued for its upright growth and aromatic foliage. Native to North America, it develops clump-forming stems with oval, toothed leaves and produces tall spikes of lavender-blue flowers during the warm season. The plant adapts well to temperate and moderately warm climates and performs best in full sun with well-drained soil. It is suitable for herb gardens, borders, and naturalized planting, where it attracts pollinators such as bees and butterflies. Seeds germinate readily under warm conditions and may benefit from light exposure or mild stratification to improve success.
