About Candle larkspur
Delphinium elatum, commonly known as tall larkspur, is a striking herbaceous perennial from the Ranunculaceae family, prized for its majestic spires of flowers that can reach considerable heights. Its blooms, often in vibrant shades of blue, purple, white, or pink, appear from early to mid-summer, adding a spectacular touch to any garden. It is ideal for the back of borders, mixed beds, or as a cut flower, where its height and color can be fully appreciated.
