Iris graminea
Iris graminea is a species of rhizomatous flowering plant native to North American wetlands. It blooms with delicate, large, lavender-blue flowers on top of a slender stem with sword-like foliage. It is frost-sensitive and prefers well-drained moist soils. It grows to about 20-50 cm in height and spreads through underground stems called rhizomes. It will bring beauty and colour to any garden. To ensure best results, split the clump and replant 26-30 cm apart.

watering
Iris (Iris graminea) require regular watering and good drainage. For best results, water your Iris plants deeply every 7-10 days. Make sure to water the soil evenly and not to water the foliage directly, as wet foliage can lead to disease. During periods of dryness or hot weather, increase the frequency of watering so the soil stays consistently moist. Watering during the summer months should be done in the morning hours to reduce evaporation and give your Iris the best chance to grow strong and healthy.
sunlight
Iris graminea requires a full to partial sun exposure of at least 6 hours a day for optimal growth. This species should be planted in areas with a good source of light and that are not overly shaded. The ideal time to receive this sunlight is during the morning and late afternoon. If possible, direct sun from the midsummer should be avoided, though the sun in the spring and fall are beneficial to this species.
pruning
Iris graminea should be pruned once a year in the early spring, as soon as the danger of frost has passed. Pruning should be done to remove dead foliage, as well as any excessive growth that is blocking light from reaching the new growth in the center of the plant. Cut back the foliage all the way down to the rhizome (the white, horizontal stem that grows below the soil). Once the dead material has been removed, sprinkle some slow-release, nitrogen-rich fertilizer around the base of the plant. Cutting back the foliage not only improves the overall appearance of the plant, but it also increases airflow, which helps to prevent fungal infections and other diseases.

should Iris grow in spring or fall?
Iris plants should be grown in the spring. This is the best time of year to plant them as the days are beginning to warm up and there is adequate rainfall. They are able to grow roots before the soil temperatures become too hot or cold. Depending on the United States plant hardiness zone, Irises should be planted in late winter through early spring. Also, since they are heavy feeders they will benefit from having access to nutrients and moisture during the spring season.
Is the Iris a Perennial?
Yes, the Iris is an herbaceous perennial. This means it dies down to ground level each year but returns with new growth in the springtime. Furthermore, some species may naturalize and spread over time in favorable conditions. Irises can be found in a variety of colors and forms, from large and tall flower spikes on Bearded Irises to delicate blooms atop the Japanese Iris. The Iris is a versatile and low-maintenance plant that can bring a beautiful array to any garden.
Are Irises suitable for container gardening?
Yes, Irises are suitable for container gardening. They do very well in well-draining soil and require full to partial sun exposure. When growing them in containers, make sure the containers are wide enough to accommodate their roots and they are planted in a soil mix with some organic material such as compost or peat moss. It's important to keep the soil evenly moist and water when the soil dries out slightly. Be sure to fertilize the irises with a balanced fertilizer every month during the growing season for best results.
