Sow your Silene 'Blue Angel' seeds NOW

UK readers will have received a packet of Silene coeli-rosa 'Blue Angel' with their May issue of the magazine. Seeds can be sown from March to early June - so there's still time

Silene coeli-rosa 'Blue Angel' is a charming, hardy annual offering rounded cushions of electric blue flowers, all summer long. Lovely sown in flowing drifts at the front of a sunny border or in a container.


Here's how Great Dixter head gardener Fergus Garrett described the plant when he chose it as a favourite for June in his Plantsman's Favourite series in the magazine back in 2013.

Silene 'Blue Angel' c. Sharon Pearson

A wonderful annual, hugging the ground with tussocky rosettes of grey-green leaves, above which float a dense tangle of smooth upright stems carrying a profusion of flowers in the most stirring shade of vivid blue. Each flower is approximately 3cm across and made up of a flat disc of five petals each notched at the tip and joined in the centre by a distinct black eye. Showy over a long season and dainty enough to run through empty spaces among perennials, imitating self-sowing. Mixes well with Lychnis coronaria and Eryngium giganteum.
