Tall Hyacinth-Flowered Larkspur is a stately and elegant annual, producing dense flower spikes packed with delicate, hyacinth-like blooms in rich shades of blue, purple, pink, and white.

With its upright form and airbrushed, vintage charm, it adds structure and romance to garden beds — and is a magnet for bees and butterflies.
