About Two-color larkspur
Delphinium bicolor, or 'bicolor larkspur', is an attractive perennial native to North America, valued for its distinctive floral spikes. Its flowers, often in shades of blue and white or purple and white, form dense inflorescences that stand out in cottage gardens, mixed borders, and as cut flowers. It brings elegant verticality and a vibrant touch of color to any landscape.
Native range
North America, specifically in the western United States and southwestern Canada
Care tips
It prefers full sun to light partial shade and fertile, well-drained soil rich in organic matter. Keep the substrate consistently moist, especially during dry periods, but avoid waterlogging which can lead to root rot. A common mistake is the lack of support, as its tall flower stalks may require staking to prevent them from bending in the wind or from the weight of the blooms.
