Larkspur blooms in early summer, the flowers emerging on loose spikes in several colors: pink, white, red and navy-blue.Larkspur plants grow about 45-60 cm (18-24 in.) tall, they make a beautiful display planted in small groups or as a contrasting background to smaller flowers.
- Larkspur can be grown in most areas, except tropical regions.
- They prefer full sun but not hot weather and they must be protected from strong wind.
- It needs well drained, moist soil.
- Water regularly but do not over-water.
- Planted in groups, spaced about 15 cm ( 6 in.) apart, they will hold each other up, otherwise they will need staking.
Deadheading will force the plant to produce side branches with new flowers.
- Unlike the perennial delphinium, larkspur consolida is a self-seeding annual plant but you can help.
- Collect the seeds after they dry on the plant.
- Sow the seeds in autumn for flowering the following spring, where they are to grow. The seedlings can tolerate extreme cold in winter but they don't like to be moved.
