The Larkspur Delphinium is winter hardy. During the cooler months, the plant is reduced to a rosette of leaves draped across the ground. However, this rosette recedes before the 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 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!

Landscape Uses and Maintenance - Larkspur Delphinium

These plants require deadheading for extra blooms, and occasional staking to make sure they do not topple over. However, they can be susceptible to slugs, so protected them appropriately. Once they are established, they are rabbit and deer-resistant, making them a great plant for gardens close to wildlife habitat.

Due to their maximum height of 4 ft, they make a great back drop of a floral garden bed in full sun. Plant these flowers along with other native wildflowers to attract a myriad of pollinators to your garden. They are reliable bloomers year on year.

HAve not recieved the order yet

While I have not yet received my order I fear that there is not sufficient time to get the plants established prior to Bend Oregon's first frost / hard freeze.

WHile I am confidant in the year guarantee, I do not want to loose the plants overwinter.
