Delphinium elatum - Cobalt Dreams

The most outrageous blue you can invite into the garden, Delphinium elatum ‘Cobalt Dreams’ is a jumbo perennial delphinium with towering royal-blue flower spikes that look positively regal in borders, cottage gardens, and cutting beds. This is no mildew-prone little wimp that disappears after one season — ‘Cobalt Dreams’ Delphinium is reliably perennial, multi-spiking, and gloriously extra-large-flowered, reaching 4–6 feet tall and about 18–24 inches wide when happy.

The sumptuous cobalt-blue blooms make spectacular cut flowers and bring dramatic vertical color wherever a garden needs height, romance, and a little botanical fanfare. Butterflies love the blooms, while deer tend to leave this beauty alone.

Plant Delphinium elatum ‘Cobalt Dreams’ in full sun to light afternoon shade with rich, loamy, well-drained soil. Add compost in spring and summer to encourage those huge, heart-stopping spikes. After the first bloom show is spent, cut plants back to about 6" tall for a repeat performance. Tall, bold, and absolutely breathtaking.

Because the mature spikes can reach 4–6 feet, shelter from strong wind or provide discreet support before the flowers become heavy. Give this blue exclamation point a destination in our Delphinium collection.

Safety note: All parts of this plant are toxic if ingested. Keep away from children and pets, and do not use any part as food.
