Bearded Iris
A bearded iris is a hardy perennial that requires little maintenance. The flowers of a bearded iris have six petals; three upright, called standards, and three hanging, called falls. The flower gets its name from the falls, which have a fuzzy line, or beard, that runs down the middle of each. The blooms of a bearded iris come in many colors, including white, yellow, pink, blue, purple and bi-colors.

Most bearded iris bloom in the spring, but some of the newer cultivars will re-flower in the summer and fall. This second flowering is not as showy as the spring bloom. There are several thousands of bearded iris cultivars, and they come in many different sizes. There are dwarf, intermediate, border, and tall bearded iris, to name a few of the more standard sizes.

Bearded iris, like all other iris, has a thick fleshy root called a rhizome. The rhizome is where most of the nutrients are stored. The rhizomes of a bearded iris will grow best when planted near the surface of the soil. Keeping the rhizomes firm and healthy is an integral part of the success of the plant. Providing good drainage, with moist soil deeper down will result in a more robust rhizome and a healthier plant.

A bearded iris prefers full sun exposure to thrive, but some colors hold better in partial shade. Too much shade will prevent flowering, or greatly reduce the bloom length. Bearded iris should always be planted in late summer through early fall. This will allow them to establish themselves before winter. Fertilizer should be applied around, but not directly on, the rhizome.
