Growing Mighty Atom 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. For easy companion plants, pair with our cottage garden blue collection.

Mighty Atom creates a mighty display planted en masse, and delphiniums are a fabulous companion plant for roses - it would look lovely alongside 'A Whiter Shade of Pale'. Lupins like 'Blossom' make excellent partners.
