Iris 'Perry's Favourite' (Sib) Overview

Iris 'Perry's Blue' is a clump-forming bulbous perennial ideal for planting in the marginal areas around ponds, or in wet areas. It has slender, strap-like, grey-green leaves and in early summer, eye-catching sky blue flowers with white and yellow markings towards the inside of the petals. Fully hardy, Iris 'Perry's Favourite' - as Iris 'Perry's Blue' is also known - likes a sunny position and moist/wet, poorly-draining soil. Pot up using aquatic compost or poor/stony garden soil. Needing little care, flowers can be removed from stems as they fade, and dead or dying leaves can be cleared as needed. Some people have experienced skin irritation when handling this plant; wearing gloves is advised. Keep an eye out when young children or pets are near as all parts of this plant are toxic, causing discomfort if eaten.
