Description

Pastel-perfect Iris ensata 'Cupcake' is certainly a sweet summer treat for the eyes! The generous white blooms feature a mouth-watering array of candy colours, including lemon yellow flashes and delicate violet veining. From the Dinnerplate Series, these unmissable blooms can grow up to 15cm across, and you can be sure the bees and butterflies will appreciate this delightful confection too. It’s best to position the pretty Iris ensata 'Cupcake' in full sun for the biggest and best blooms, but it will grow quite happily in partial shade too. 

Iris ensata are much prized as marginal plants, preferring a soil which is continually moist, and somewhat boggy. A special variety like Iris ensata 'Cupcake' will be a real jewel in damp borders, pond or stream edges. The sword-shaped foliage will die back in autumn and can be trimmed to just above ground level for a neat and tidy display. This perennial is fully hardy and will grow back every year, eventually multiplying and treating you to more of those gorgeous blooms.

Useful information

    • Soak your Iris ensata 'Cupcake' roots in water for 3-6 hours prior to planting.

    • Plant your "Japanese water iris" bare roots into temporary pots with a multipurpose compost in spring and grow-on in a sheltered spot outdoors.

    • Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed.

    • Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
