Delphinium General Information

Delphinium grandiflorum tend to be more heat tolerant then the traditional taller hybrids. Needs good drainage. Delphinium are elegant and exquisite with colorful flower spikes that add a majestic touch to your garden. A choice flower for the hardy border. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Delphinium Plant Care

As with most delphiniums, a moist, rich soil is needed and regular feeding and watering are recommended. Lanky or bent stems can be cut back by one half to force new growth at the base. As with Digitalis and Lupines, cut off most faded flowers so they do not exhaust themselves in seed production. Allow some self seeding to ensure future generations.

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!

100% Guarantee

We offer a 100% guarantee for all our perennials to reach you in good condition and to grow. If you're not satisfied, we'll reship or refund immediately. Please don't hesitate to contact us if you have questions or concerns—we share your passion for gardening and want your new plants to thrive in your border!
