Iris versicolor 'Kermisina'
Harlequin flag iris
This is a true water Iris from streams, marshes and bogs of North America.
It will grow in shallow water up to 10cm above the rhizome or in very damp soil and should not be allowed to dry out.
Long, mid-green sword like leaves grow to almost 60cm long and the sturdy flower spike towers above them. Each stem can produce up to five flowers in a luscious dark purple. The six petals open to a triangular shape showing the inner markings of yellow and white, marbled with purple veins.
Flowering in their second year, the clumps will become substantial but are easily divided every three to four years.
Terrific for pond edging.
