This deer- and rabbit-resistant perennial is bee friendly and attracts butterflies and hummingbirds. Use Cobalt Dreams Larkspur in many ways, including as a tall focal point in garden beds and in mass plantings, for a stunning effect.
Cobalt Dreams Larkspur Care
Larkspur thrives in full sun and in well-draining soil that is rich in organic matter. Water regularly, particularly in the heat of the summer, to keep the soil evenly moist. Because of its mature height of 4-6 ft., it may be necessary to stake it when in full bloom. Deadheading to remove spent flowers will promote and extend blooming.
To promote healthy, sturdy growth, prune Larkspur back to one-third its size in early spring. Cobalt Dreams Larkspur can be divided and transplanted either in the spring or fall. Apply a layer of organic mulch around the root zone in winter to protect it from harsh freezing weather; reapply a thin layer in spring to retain soil moisture and suppress any weeds.
Cobalt Dreams Larkspur Spacing
When planting in mass groupings, space Cobalt Dreams Larkspur 2 ft or more apart, measured center on center, to allow for its mature width.
