About this plant
This is a rather slender, gentle looking iris that reaches 60-75cm (2ft-2ft 6in) in height. The foliage is upright with blue-purple flowers that have darker veining and a cheery yellow blob on their falls (lower petals). The flowers appear in early summer and have the simple grace of the wild species.

Spring
Spring · Outdoors
Feed with aquatic plant food
As the plant is grown in water, feed with an aquatic feed as directed on the packet. Do not exceed the amounts given as this can affect the water.
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Outdoors
Water frequently to keep the soil moist
The plant thrives in moist or boggy soil, doesn't tolerate dryness and should be watered frequently, not only after a period of drought, but if the soil begins to dry out spring to autumn. Check plants in pots more frequently, especially in hot weather.
