Delphinium
 Common Name: Delphinium or Larkspur
Botanical Name: Delphinium hybrid
Family: Ranunculaceae
Origin
The delphinium genus includes more than 300 species of flowers native to the Northern hemisphere. The name pronounced del-fin-ee-um, is derived from the Greek word for dolphin because the flower spurs resemble a dolphin’s head.
Garden Grandeur
An easy to grow garden favourite, delphiniums prefer full sun to partial shade in well-drained soil. The flower spikes bloom from bottom to top with cup-shaped blossoms, which are 1" across. Flowers are available in a variety of colours including: various shades of blue, lavender, white, and pink.
Creative Curves
Available year-round, but the peak supplies are from May to September. Delphiniums make ideal additions to garden-style arrangements. The tall flower spikes gathered in tall, cylindrical, or square vases create a dramatic look. Hybrid delphiniums are prime flowers for creating interest, increasing perceived value. Delphinium's unique blue colour has an ‘old fashion’ appeal that blends well with most other garden flowers.
Design Tips
The spikes should have open flowers along the bottom half of the stem, and buds on the upper half of the stem should be showing colour. Cut at least one inch off the bottom of the stems, on an angle under water. Place the flowers in water immediately. Due to the delicate nature of delphiniums, handle them carefully to avoid breaking off the blooms from the stems. Depending on care-and-handling practices, delphiniums’ vase life ranges from 7-14 days. Delphiniums are particularly ethylene sensitive. Larkspur leaves and flowers can cause stomach distress if ingested, and sensitive people may get a rash from contact with the foliage. The seeds are also poisonous.
