This plant is winter hardy. During the cooler months, the larkspur plant is reduced to a rosette of leaves draped across the ground. However, this rosette recedes before the larkspur flower blooms in the spring. Full sun to partial shade is most appropriate for these beautiful, tall flowers. While they can tolerate many different soil types, they do best in dry to moderate, humus-rich, fertile soils.
The plant gets its name from the Greek word for dolphin, "delphis", which is a reference to the shape of the flower bud. Interestingly, the seeds of this plant are medicinal and have been used to cure head lice when soaked in alcohol. However, they are toxic if ingested, so be wary!

These Delphiniums are breathtaking. My neighbors keep asking where I got them. They light up my garden.
I planted them a month ago and already seeing strong stems. Can’t wait for full bloom. Would have liked a bigger size plant.
The flowers are gorgeous and bright, but shipping took a little longer than expected. Still very pleased overall.
My Larkspur is alive and growing but doesn’t look nearly as tall or colorful as the pictures. Might just be my climate though.

How To Grow
How to Grow and Care for Bare Root Perennials, Tubers, and Bulbs
Bare root perennials, tubers, and bulbs are an easy and economical way to jumpstart your garden with lasting beauty. These dormant plants should be planted in early spring or fall while the soil is cool and workable. Before planting, soak bare roots in water for 1–2 hours to rehydrate them. Choose a location based on the plant’s light needs—most flowering types prefer full sun, while others thrive in partial shade.
For bare root perennials, dig a shallow hole and spread the roots out naturally, ensuring the crown is level with the soil surface. For tubers and bulbs, plant with the pointed side facing up at a depth about two to three times their height. Cover with soil, gently press down, and water thoroughly.
Keep soil consistently moist (not soggy) until new growth appears. Add mulch to retain moisture and suppress weeds, but avoid covering the crown or bulb tops. Once established, these plants require little maintenance—just seasonal watering, occasional dividing, and deadheading or pruning as needed. With proper care, they’ll return and thrive year after year.
