species iris

Iris spuria subsp. carthaliniae should be watered 1-2 times per week in the spring and summer. In the fall and winter, it should be watered only when the soil is entirely dry (approximately once every 3-4 weeks). Water regularly and evenly, allowing the soil to dry slightly between watering. Water in the morning or evening, and avoid getting any foliage wet.

Iris spuria subsp. carthaliniae is a species of spuria iris, an easy-to-grow hardy perennial. These plants are native to eastern Europe, but can be grown successfully in USDA hardiness zones 4 through 9. Iris spuria subsp. carthaliniae prefers a spot in the garden that has full sun for at least 6 hours per day. In regions with very hot climates, providing some afternoon shade can help protect the plants from heat stress. These tough plants can survive in part shade, but their stems will be shorter with fewer blooms. In addition, Iris spuria subsp. carthaliniae can tolerate some inundation by water, making it ideal for planting around rain garden plans.

Iris spuria subsp. carthaliniae should be pruned annually in the late winter or early spring, when temperatures are still cool and before new growth begins. When pruning, only dead or damaged leaves and canes should be removed. The remaining foliage should be trimmed back to a height of about 6 inches to encourage bushy, compact growth. If necessary, older canes can be cut almost to the ground if they are becoming ineffective in propping up the uprights. Remove any stray branches and suckers as they appear. If desired, the tips of healthy stems can also be pinched back in spring in order to further promote branching and growth.
