Showy perennials are plants that bloom year after year and are known for their vibrant colors and large blooms. Two examples of showy perennials are croci and irids. Croci are a type of flowering plant in the iris family, with six petals and a trumpet-shaped center. They come in a variety of colors, including yellow, white, purple, and orange. Irids are also a type of flowering plant, with three petals and three sepals. They come in a wide range of colors, from blues and purples to yellows and oranges. Both croci and irids are popular choices for gardeners looking to add a splash of color to their outdoor spaces.
