Grown for their brilliant colors and distinct look, irises form a large genus of perennials. Some of the perennials are bulbous, and others are rhizomatous. They’re definitely some of the best outdoor perennial flowers. Irises are easy to grow and make excellent cut flowers. They come in a wide range of colors, including blue, purple, pink, white, and yellow. Different varieties bloom at different times throughout the spring, so it is possible to have irises blooming in your garden from early spring right through to summer. Here’s a list of the best irises to grow outdoors:
Bulbous vs Nonbulbous Irises
Bulbous irises are the most common type of iris, and they come in a variety of colors. A bulbous flower is one that stores its energy in an underground bulb, much like an onion. The bulb acts as a food reserve and produces new leaves, flowers, and stems each year. Bulbous irises include the popular Dutch Iris (Iris x hollandica) and the lesser-known Iberian Iris (Iris setosa). If you are looking for a dramatic, colorful addition to your garden, then consider planting some non-bulbous irises. These beautiful flowers are easy to grow and will provide you with months of joy.
Rhizomatous and Bearded Irises
Rhizomatous irises have an underground stem that grows horizontally, just below or at the soil surface. They make some of the best outdoor perennial flowers because of how hardy they are. Each year, new leaves, flowers, and stems sprout from this horizontal stem. The leaves are isobilateral. Many of the most popular iris varieties are rhizomatous, including the bearded iris (Iris x gica), Japanese iris (Iris ensata), and Louisiana iris (Iris nelsonii). Bearded irises flower in the early spring and continue until the summer. They are usually small, reaching a dwarf size of around 8-16 inches and a tall size of 28 inches or more. You should grow bearded irises in well-drained, acidic soil. Put these irises in direct sunlight for the best results.
