Blue Flowers: True Blues Are Rare
True blue pigment is uncommon in garden flowers. What florists sell as blue is often hydrangea, iris, delphinium, or a dyed carnation. Blue hydrangeas are a garden-chemistry story as well as a florist colour.
Association: Calm, apology or uniqueness in modern use.
Occasions: Thank-yous, weddings with a blue palette.
Season: Hydrangeas peak in summer. Dutch iris is spring. Dyed 'blue' carnations are year-round.
