Dragonhead flower seeds produce upright annual or short-lived perennial plants with spikes of violet-blue blooms and attractive green foliage. Suitable for cottage gardens, borders, pollinator-friendly gardens, cutting gardens, and meadow-style planting, these ornamental flowers grow well in fertile, well-drained soil with regular moisture and full sunlight. Their vertical flower spikes provide seasonal color and texture while blending naturally with other flowering plants in decorative outdoor landscapes throughout the growing season.
