Bearded Iris (Iris germanica), specifically a yellow type with reddish-brown veining, often referred to by historic names like ‘Sans Souci’ or ‘Honorabile’.These perennials thrive in full sun and require well-draining soil, as they are susceptible to rhizome rot if kept in waterlogged conditions.To maintain the plants, spent flower stems should be removed after blooming, and foliage can be cut back to roughly 6-inch fans in late fall.They are relatively easy to care for and can be propagated by dividing the rhizomes every few years to encourage vigorous growth
