Prairie Larkspur
Delphinium exaltatum
Prairie Larkspur stands out with its impressive height and stunning, vibrant blue flowers. Each spike can host dozens of small, star-shaped blooms, creating a dramatic vertical element in the garden. This species prefers cooler climates and performs best in locations with full sun to partial shade and well-drained, fertile soil. While it is a breathtaking addition to perennial borders, it requires some care to thrive, including staking to support its tall stems and protection from strong winds.

Maintenance Tips
- Requires regular watering, especially during dry periods, to keep the soil consistently moist.
- Deadheading spent flowers will encourage a second bloom.
- Due to its height and relative delicacy, staking is recommended to prevent stem breakage, especially in windy areas.
- Watch for slugs and snails; treat for powdery mildew and other fungal diseases as needed.
