      8 Types of Irises

      1. Bearded iris (Iris germanica)

        The most common type of iris is the rhizomatous Iris germanica. It has sword-like leaves and fuzzy petals. The bearded iris does not produce seeds. Instead, it spreads from plant to plant through its root system. This makes it a perfect choice for landscaping.

It grows well in USDA zone 4 – 8 and can bloom continuously throughout the summer months of July and August. It is a great choice for gardening beginners, as it will grow very well in containers.

          3. Siberian iris (Iris sibirica)

          The Siberian iris is a rhizome iris that flowers in early spring. It has a long stem and large fluffy blooms. It can tolerate more frost than most other irises. It’s great for gardeners who want the blooms to look long into the summer and grow in colder areas.

          4. Dutch iris (Iris hollandica)

Dutch irises bloom all year round if not overwatered or underfed. They grow well in containers, have a long flowering season, and can survive frost.

          5. Beardless Irises

          These are irises not found natively in North America and are more scarce than the other types. They are grown using seeds planted in the soil. Flower colors include blue, pink, purple, and white for single blooms or clusters of colors for double blooms.

          6.Crested Iris (Iris cristata)

          Crested Iris is a new kind of iris that was discovered in the late 19th century and was named after the shape of its bloom. It grows very well in containers, has soft grassy-like foliage, and blooms early in spring with a double crest of bluish flowers.

          7. Yellow flag iris (Iris pseudacorus)

          It is a beautiful all-season bloomer with yellow and creamy white flowers. This iris blooms from early spring through fall but can be grown outside in cool areas. It is hardy to USDA Zone 3 and needs to be protected from frost.

          When to Plant Irises

          Irrigated irises can be planted in the fall, though rhizomes can be planted in the summer. In general, rhizomes will grow a more traditional iris (with broad leaves and a central stalk), while bulbs will often produce long, thin stems typical of bearded irises. Irises thrive best in USDA hardiness zones 3–9.

          How to Grow Irises

          The best way to care for an iris cultivar is to plant it in rich soil that is kept moist so that the bulbs can easily form. It should not be allowed to dry out. Feed young plants with a monthly liquid fertilizer throughout the growing season. Keep the foliage clean by removing dead or damaged leaves.

          Watering once or twice a week during the growing season is sufficient to prevent wilting. Set your bulbs out after the last frost, and then remember to mulch with several inches of compost, manure, or peat moss.

          Care for Irises

          Irises are a great container plant to grow, and they will produce beautiful blooms all summer. Most iris can handle a little drought, especially in the summer, but you can keep them well-watered by mulching them with pine or cat litter. They will grow in loose soil, and if you live in an area that doesn’t experience harsh winters, you could put them outside for winter.

          Iris are climbers, so the majority of their roots gather low to the ground and are easily reached. They also tend to bolt and need months of cool weather to produce blooms. If you don’t have an area for them, you could grow them in a glass terrarium. Irises don’t need as much light as most other flowers, but they will do best in bright indirect sunlight with plenty of water so that it doesn’t dry out between watering.

          That can be hard if you live in a city or location with less sun exposure than the suburban gardens that seem to be ubiquitous these days. Even with many hours of direct sunlight, though, your irises will still turn up beautiful colors like this one:
