About Royal larkspur
Delphinium variegatum, commonly known as royal larkspur, is a striking annual native to California, characterized by its intense blue-violet flowers, often with a white or yellow 'eye'. Its erect floral spikes add a vertical and vibrant touch to cottage gardens, mixed borders, or large containers. It's an excellent choice for attracting pollinators and creating focal points of intense color.
Native range
North America (primarily California, USA)
Care tips
This species thrives in full sun or light partial shade in very hot climates, and prefers well-drained soil rich in organic matter. Keep the substrate consistently moist but not waterlogged, especially during flowering. Avoid excessive nitrogen fertilization, as it can promote leaf growth at the expense of flowers. It's crucial to protect it from strong winds, as its flower stalks are delicate.
