Growing Blue Nile Delphiniums

Delphiniums prefer full sun, with well-drained fertile soil. They're tall, so position towards the back of a south- or west-facing border, with a bit of space around them so that their leaves aren't shaded much.
If your site is exposed to the wind, you'll need to stake them in late spring, before the foliage really gets growing.

Slugs and snails can ruin young plants, so be prepared.

Feed every 2-3 weeks in the flowering season, and cut back spent flower stems promptly in order to encourage a second, less dramatic, flowering at the end of summer. Cut back everything in late Autumn.

In Your Garden Design

A classic among cottage garden perennials, delphiniums grow up to create the most wonderful pillars whose vertical accents contrast handsomely with the rounded, spreading and fan shapes of your other border perennials, especially at the back of the border with our cottage garden blue collection as a ready-made match.

The tall flowers of the Blue Nile add spectacular punctuation and structure to any border. They are good planted alongside white delphiniums such as 'Moonbeam' or the white member of the 'Guardian Collection', or paired with a Clematis 'Armandii' trailed behind it and a Geranium 'Rozanne' in front. As with all delphiniums, it is a fabulous companion plant to roses - try a pink one with a little blue in it, such as the luscious 'English Miss'.
