Delphinium Seeds

Delphiniums stand as beacons of the bountiful blooms of summer, pairing beautifully with bright bunches of cosmos or the rich tones of shrub roses. These seeds also offer flexibility in when they can be sown. For a same-year bloom, sow your seeds in an indoor pot or seed tray between February and April. Outdoors, you can prepare for next year’s bloom by sowing between April and June or September and October.

For delphiniums that bloom tall and majestic year after year, plant in fertile soil that is moist but well-drained, with plenty of sun. Water well during dry spells, and mulch with organic matter to retain moisture. For more flowers, apply a high-potassium liquid feed every two to three weeks, and deadhead spent blooms. Plants are best in a position sheltered against the wind and are traditionally given support to keep them tall and upright.  These gorgeous blooms will turn your garden into a thriving pollinator zone, attracting bees and butterflies with each new year.
