Pansy Aalsmeer Giants – Viola. Richly blooming mix of extra large-flowered pansies with a small dark red patch in the heart of the flower. Violet flowers are edible. All violets are generally biennials, but the annual culture is recommended. Sow seeds early in the spring, if necessary in an unheated greenhouse, prick out or transplant directly from the seedbed to their final spot in the garden.
