Delphinium. One of the reasons that Delphinium are so beloved is due to the incredible shades of blue that they can provide. 'Cobalt Dreams' will knock your socks off with its astounding colour and tall architectural spikes. Can often re-bloom in late summer after deadheading spent flowers. No other perennial can instantly give an English Cottage feel to a space like a clump of Delphinium flower spikes in mid summer. The towering height, cool, pastel shades and long-lasting flowers are an old-fashioned favourite and make an incredible cut flower. Height 36-52". 2.5" plug.

Some Perennials will be shipped to you from our greenhouses. They will be in pots and may have actively growing green leaves. These pots should be immersed in water upon arrival to thoroughly soak the root ball. These growing plants must be hardened off before planting outside. Keep in a cool bright room, and place outside on mild days and gradually leave outside for longer periods of time. After a week or so, or when nighttime temperatures are above freezing, plant outside. If a severe dip in temperature is expected, you may want to place straw or an old blanket over the green leaves to protect them from severe damage. Frost or cold will not permanently hurt the plant, but it may damage the new leaves and set growth back.
Delphiniums can be grown in full sun or partial shade, though full sun may help to prevent powdery mildew. When planting, be sure to set the crown at or above soil level to avoid rot. Since their stems are hollow, taller varieties of Delphiniums should be staked to prevent damage from wind and rain.
They grow best in rich, well-drained soil with a basic pH. If your soil is naturally acidic, adding lime will help to provide these conditions. They are also heavy feeders. The addition of compost or manure to the soil as well the use of granular fertilizer will result in healthier, stronger plants.
Please note: Wear gloves when interacting with delphiniums if you tend to have sensitive skin.
