Delphinium is a stately, elegant perennial that is a standard in English cottage gardens. Mounds of dark green, glossy foliage are adorned with huge spikes of showy, spurred flowers in early summer. The plants bloom in late spring to early summer, and the flowers are suitable for cutting. Good for cut flowers. Select a site with full sun to light shade and well-drained soil. Choose an area protected from strong winds to keep tall, top-heavy varieties from blowing over.
