Spuria Iris are an excellent cut flower much loved by flower arrangers for their tall spikes and durable flowers which look much like Dutch Iris. They do not like being moved so plant in a sunny, well drained spot where they can remain undisturbed for years.
Spuria are dormant over summer with foliage dying off after flowering. They should not be watered over this time, but can be generously watered during their growing period from May onwards. Give them dolomite in acid or neutral soils and an occasional application of old manure or compost, plus a light dose of complete fertilizer in August.
Rhizomes will be available in Autumn (around Easter) and should be planted immediately. They may not flower in the first Spring after transplanting.
