Delphinium

What is the plant

Consolida differs from other species of Delphinium (mostly perennials) in the flower structure, with only one united petal, rather than the four separate petals (or more in cultivars) found in other delphiniums, and in the fruit, which comprises a single follicle, instead of a cluster of 3~5 together. It is a popular garden plant and cut flower, grown from seed every year, with numerous cultivars in shades of pink, blue, purple and white. In seed catalogues it is usually labelled as larkspur, a common name referring to the shape of the spurred calyx, with "delphinium" reserved for its perennial relatives.

How to Care for the Plant

Water
Larkspur doesn't like to stay wet for long periods of time, but it does need consistent moisture. Be sure that plants stay evenly moist, especially when flowering. If they remain too dry for too long, plants can become stunted and have poor bud set, so you may miss out on blooms.
Pruning
If they do become invasive, remove the spent stems and pull up any unwanted recruits.
Fertilizer
In early spring, add a thin layer of compost and a 2-inch layer of mulch to help hold in the moisture. This will also control the weeds growing on larkspur flower beds.

Sunlight
For the best blooms, plant larkspur in full sun. Although plants can handle a small amount of shade, they are more likely to flop and require stakes. You can prevent this by planting larkspur near tall neighbors to act as a support system, by sowing plants densely, or by planting them along a wall or structure.
Soil
They can tolerate most soils, but if you want the best results, go for light, well-draining soil. If your area has heavy soils, you can amend them with compost or manure.
Container
Use containers that won’t topple under the weight and height of the growing larkspur flowers.
