Siberian iris (Iris 'Caesar's Brother') is a stunning perennial and a true show-stopper in the garden. Rich, royal purple blooms on tall stems make a grand statement in the garden. These tall, upright flowers have a refined style that adds beauty and structure. The flowers arrive in early summer and last through the season.

watering

Siberian iris (Iris 'Caesar's Brother') should be watered moderately and consistently throughout the growing season. During the warmer months, water the plants deeply about once per week, or more frequently if there are periods of prolonged dryness. Allow the soil to dry out slightly between waterings to encourage robust root growth. In the cooler months, water only when the top layer of soil feels dry. Reduce waterings if you notice the foliage beginning to yellow. Let the soil dry out completely during winter dormancy.

sunlight

Siberian iris (Iris 'Caesar's Brother') does best in full sun to partial shade. For best results, it should receive at least 4-6 hours of direct sunlight each day. In areas with long hot summers, afternoon shade is recommended to prevent wilting. In cooler climates, plants may require more sunlight to ensure sufficient blooms.

pruning

Siberian iris (Iris 'Caesar's Brother') should be pruned annually in the spring, shortly after the flowers have faded and the leaves have died back. Pruning should consist of trimming the leaves and inner stems back to the base, using sharp pruning shears. Deadheading, or pinching off spent flowers and seedpods, is also recommended. Pruning will help keep the plant tidy and healthy.
