Sweet Pea Azureus delivers a brilliant azure-blue, often with a soft pink tinge, an exclusive color not often seen in the garden. On long, wispy stems of greenery, Azureus can best be interlaced between more focal flowers as a greenery/filler combo in cut flower arrangements. Azureus is not fragrant, and it’s not technically a sweet pea; it’s more accurately referred to as a grass pea, or Indian pea.
