Spuria iris are a different type of iris with flowers very similar to the Dutch Iris, only they have much larger flowers and lots of different colours. They have a tall sword like leaf which grows profusely as soon as the colder weather starts, ie from March, and continues throughout the winter months so by Spring time they produce a tall clump of green leaves which break out into flower about October.
They make a great background plant in a garden bed during the winter months and springtime. They die down after flowering in late October/November and require very little if any watering at this time. They reappear in Autumn when the weather cools down and grow through the winter with lovely sword like green and lush leaves.
They grow into large clumps and are tall so give them a bit of space and preferably at the back of the garden bed. They can be left undisturbed for years.
Spuria iris make wonderful cut flowers because the stalk can be cut whatever length desired. Flower spikes can reach 100cm to 120 cm tall.
