Agastache seeds produce hardy perennial plants with an upright, bushy growth habit and aromatic foliage. These plants develop spikes of tubular blooms over an extended period and are well adapted to warm, sunny climates. Agastache thrives in full sunlight and performs best in well-drained soil with moderate watering, becoming drought-tolerant once established. Suitable for garden beds, borders, pollinator gardens, and containers, it establishes easily and provides long-lasting seasonal color.
