Delphinium
Delphiniums are among the most dramatic and architecturally striking flowers in floristry. Their tall, towering spikes of densely packed blooms in shades of blue, purple, white, and pink add height, structure, and a sense of grandeur to any arrangement. They are a florist's favourite for statement bouquets and a garden lover's favourite for their cottage-garden charm.
What each delphinium colour means and when to gift them
Blue delphiniums are among the most prized flowers in floristry, simply because true blue flowers are exceptionally rare in nature. Blue delphiniums represent dignity, grace, and the open sky. They are a striking and distinctive choice for anyone who appreciates something genuinely unusual in a bouquet.
Purple delphiniums carry meanings of royalty, admiration, and first love. They are a popular choice for romantic occasions and for anyone who appreciates flowers with a regal, sophisticated quality.
White delphiniums represent purity, innocence, and new beginnings. They are widely used in wedding flowers and sympathy arrangements, where their tall, elegant spikes add structure and height without competing with other blooms.
Pink delphiniums communicate warmth, affection, and playful romance. They are a beautiful addition to birthday bouquets and Mother's Day arrangements, particularly when paired with roses and lisianthus.
In the language of flowers, delphiniums are also associated with an open heart and a strong attachment to the people you love. Their name comes from the Greek for dolphin, a reference to the shape of the flower bud before it opens.
How long do delphiniums last
Delphiniums typically last between five and ten days as cut flowers. They are not the longest-lasting stem, but their visual impact more than compensates. Their blooms open progressively from the bottom of the spike upwards, giving the arrangement a changing, evolving quality over its vase life.
Keeping delphiniums well hydrated is the single most important factor in extending their vase life. They are thirsty flowers and will drink a significant amount of water, particularly in the first 24 hours after cutting.
How to care for them
Trim the stems at a 45-degree angle on arrival and place them immediately in a deep vase with plenty of fresh, cool water. Delphiniums need a tall vase to support their height and keep them upright. Remove any leaves that would sit below the waterline.
Check the water level daily and top it up as needed. Delphiniums drink heavily. Change the water every two days and re-trim the stems each time. Keep them away from direct sunlight, heat, and draughts. As lower blooms fade, remove them to allow the upper buds to continue opening.
Are delphiniums safe for cats and dogs
No. Delphiniums are toxic to both cats and dogs, and also to humans if ingested in large quantities. All parts of the plant contain alkaloids that can cause serious symptoms. They should be kept well out of reach of pets and children.
If you need a tall, architectural flower that is safe for pets, snapdragons are a good alternative and are non-toxic to cats and dogs.
