DELPHINIUMS
There are about 300 species of annual and perennial Delphiniums. They have two blooming cycles, one in early summer and if cared for properly, again in late summer or early autumn. Blue is the most common Delphinium flower but there are numerous hybrids available in shades of pink, lavender, red, white and yellow. Blooms may be single or double. Our available colors this year are deep blue, light blue and white. We carry both short and tall delphiniums and are growing two varieties from seed.

GROWING DELPHINIUMS
Delphinium planting is normally at the back of the bed, where flower spikes can reach 2 to 6 feet tall. Delphinium flowers are often planted in groups.
Grow in fertile, well-drained soil in full sun to light shade, with shelter from strong winds.
Soil should not dry out. Water plants during the summer if rainfall is less than 1 inch per week.
Mulch helps retain moisture and keeps roots cool.
Care should include regular fertilization in spring when the plant begins to grow, and during the flowering period.
Deadhead the first blooms in early summer. Remove flower stalks when blooms are spent.
Taller varieties may require staking.
