Delphinium Pacific Giant Summer Skies

The most majestic annual in the cottage garden. Delphinium Pacific Giant Summer Skies produces towering spires of large, semi-double blooms in a clear, luminous sky-blue with white bee centres — a colour of extraordinary purity that provides the vertical drama and classic English cottage garden presence that no other annual can match, rising to 150–180cm in a single season.

Stake early. Outstanding for cutting — one of the finest blue cut flowers available from seed.
