Delphinium 'Blue Mirror'



A dwarf variety of Delphinium, 'Blue Mirror' offers a bushy, attractive mound of deeply cut foliage that usually does not require staking. Rich, violet-blue flowers bloom to attract hummingbirds and butterflies in summer.

While Delphinium is a sun-loving plant in Northern parts of the country, it will appreciate shade from the afternoon sun in warmer climates. Here in Zone 7a in Virginia, it MUST have afternoon shade to withstand late spring and summer.

Grow Delphinium 'Blue Mirror' in well-drained, nutrient-rich soil for the best performance. It will tolerate clay soils.

Care and Growing Tips

Delphinium is a heavy feeder and will appreciate occasional compost or fertilizer before the blooming season. Be sure not to fertilize in fall, because that can encourage the plant to grow when it should be going dormant.

We ship via UPS or USPS (the Post Office), and their ship rates are automatically generated through our site. We do not profit on shipping costs. We are working with these providers to get our customers the best rates possible.

All ship times are subject to change if extreme weather conditions are present here at the nursery or at the shipping destination.

Please note: Depending on the time of year, the foliage of the plants may be trimmed to fit into our shipping boxes. This could delay the flowering of the plant, but many perennials actually benefit from being cut back.

We are currently not able to ship to Puerto Rico, Hawaii, and outside of the US.
