Tall biennials with magnificent spires of large, semi-double flowers and attractive, deeply lobed foliage. The flowers appear in a wide range of colours in early and midsummer, and it is for this that they are so highly prized.

Grow Delphinium Pacific hybrids in a sunny spot with rich, well-drained soil and provide some support before they get too tall.

How to care for Delphinium Pacific Hybrids:

For best results, plant in an open spot with fertile, freely-draining soil and protect the young foliage against slug and snail damage.

During the growing season, apply a seaweed or balanced liquid fertiliser every 2-3 weeks. While wearing gloves, stake the emerging flower spike with a stout bamboo cane and tie it in as it grows.

Cutting back the faded flower stems to a flowering side shoot will help encourage a second flush of flowers.

Sowing instructions:

Fill a seed tray with good compost, scatter the seed onto the surface and lightly cover with a little more compost. Water lightly and keep warm under glass until they are large enough to handle and pot on.

Before planting out in early to midsummer, they will need to be hardened off gradually. They will usually flower in their second summer. Seeds that are sown later in the year should be kept in pots and over-wintered in a greenhouse or cold frame before being planted out in late spring.
