Garland Daisy Seeds As healthful as it is pretty, the Garland Daisy has been used in holistic and herbal treatments because it is high in potassium, carotene and vitamins and minerals. While we don’t recommend adding Garland Daisies to your diet, we do recommend adding Garland Daisy seeds to your garden! This vibrant annual will bloom from midsummer to fall and grows 2 to 3 feet. To get the most out of your yellow and white beauties, when possible, plant them in sandy soil.
