Sublime when planted in drifts at the edges of a pond, ‘Black Gamecock’ has larger than average (up to 10cm across) flowers, in a deep shade of purple. They need consistently moist soil so make an excellent choice for bog gardens. Their flowers are mainly produced in late spring and early summer although they may have a second, smaller flush in autumn.
Garden care: To encourage healthy growth of roots, foliage and flowers, feed with a general-purpose or slow-release aquatic fertiliser. Remove yellow or brown leaves to keep the plant healthy and the water clean. Cut water iris to just above the water line in autumn if you live in a cooler climate.
