Iris hollandica (Dutch Iris)
While called ‘Dutch Iris’, this iris never grew wild in the Netherlands. Instead, it is the product of hybridizations carried out by Dutch growers. Tall and slender, it features flowers that are 4 in. wide (10 cm) with flower stalks, surrounded by gray reed-like leaves, that are very sturdy – a quality which makes them quite suitable for use as cut flowers.
