A Florist’s Guide to Larkspur
Larkspur, known scientifically as Delphinium, is a stunning perennial that belongs to the buttercup family. Characterised by its tall, striking spikes adorned with vibrant blooms, Larkspur is a popular choice for bouquets and floral arrangements. The flowers come in a variety of colours, including blue, purple, pink, and white, making them versatile for different themes and occasions.
Growing Conditions
Climate: Larkspur thrives in temperate regions, preferring cooler climates. It can tolerate some heat but does best when temperatures are moderate.
Soil: Well-drained, fertile soil rich in organic matter is optimal. Soil pH should ideally be between 6.0 and 7.5.
Sunlight: Larkspur prefers full sun, requiring at least 6 hours of direct sunlight per day. Partial shade can also be tolerated, especially in warmer climates.
Planting
Best Time to Plant: Spring or autumn is the best time to plant Larkspur seeds. For a continuous bloom, sow seeds every few weeks.
Depth and Spacing: Seeds should be sown 1.5 to 2.5 cm deep, with a spacing of 30 to 45 cm between plants to allow for airflow and growth.
Care and Maintenance
Watering: Regular watering is essential, particularly during dry spells. However, avoid waterlogging, as Larkspur is sensitive to standing water.
Fertilisation: Use a balanced fertiliser during the growing season to promote healthy growth. Fertilise again post-blooming to encourage another wave of flowers.
Pruning: Deadheading spent blooms will encourage further flowering and prevent plants from appearing leggy.
Pests and Diseases
Larkspur can be susceptible to various pests, including aphids and snails. Keeping the garden clean and using organic pest control methods can help manage infestations. Ensure proper air circulation to prevent fungal diseases.
Seasonal Notes
Larkspur is typically in bloom during late spring to early summer. They make a striking statement in garden borders, wildflower areas, and as cut flowers in arrangements.
Floral Arrangement Tips
Pairing with Other Flowers: Larkspur works beautifully with daisies, peonies, and roses, adding height and vibrancy to arrangements.
Long-lasting in Vases: When cut, they can last up to two weeks if placed in clean water with flower food. Change the water every few days to maintain freshness.
