Another classic cottage garden contender, delphiniums are tall plants, providing boldly coloured blooms. Also perfect for pollinators, these flower spires are a great addition to your borders.

Planting & growing

To start, seeds can be sown from March to April or planted outside in May to June where they will flower through summer.

Delphiniums prefer a moist but well-drained spot with full sun. However, they won’t grow well in heavy soil and wet conditions. Therefore if the borders have these conditions, add grit to aid drainage.

Then, plant them in place at the same height as they were in the pot before firming in place and watering in well.

Take good care

Due to their height, they will appreciate staking when young to keep them growing upwards strongly. When they start flowering, feed with a high potash fertiliser to boost blooms, because they are quite hungry plants.

Once they have finished flowering, cut the stems back to encourage a second round of flowers. Then, in autumn mulch the base with well-rotted organic matter or leaf mould.

Not only are their bright, bold blooms a wonderful addition to beds and borders, but they also make great cut flowers to bring their beauty indoors.
