Delphinium

Delphinium is a majestic and colourful perennial that adorns gardens with its impressive flower spikes. Delphinium is not only an ornamental plant in the garden – its tall stems and slender flowers also attract bees and butterflies, contributing to the ecological balance. With the right growing conditions, delphinium can add elegance and colour to any garden.

Delphinium thrives best in good-quality, well-drained, moist soil. It prefers a neutral to slightly acidic pH value. A well-mixed garden soil with added compost or well-rotted manure when planting helps retain moisture and ensure suitable nutrition. Drainage is essential to avoid rot and ensure healthy plant development.

Delphinium is a sun-loving plant and thrives best in full sun. It needs at least 6-8 hours of direct sunlight a day to produce its distinctive, dense flower spikes. The position should be well lit to ensure upright growth and abundant flowering. Although it can tolerate light shade, a sunny position will optimise its performance and colour.

• Candle larkspur (Delphinium elatum): The common delphinium with majestic flower spikes in shades of blue, purple or white.
