Bulbous irises in subgenus Xiphium are often referred to as Spanish irises even though there are species in this group that are found in other geographical areas besides Spain. They have bulbs with thin, fibrous roots. Hybrids in this group are referred to as Dutch Irises and they are listed after the true species on this page. Much of this species information was supplied by Rafa Díez Domínguez.

Iris 'Bronze Beauty' This is one of the so-called Dutch iris, flowers probably better known to most people as cut flowers. Iris with this brown color were seemingly more common in the past: a list from a century ago shows several in this color range in the similar Spanish Iris group. Years ago I had another handsome one called Le Mogul. Photo by Jim McKenney.
Iris 'Oriental Beauty' - Believing that Dutch Iris were rated as Zone 6 thus too tender to be grown in my colder USDA Zone 5 area, I never bothered trying to grow them, and I passed by the bins of Dutch Iris bulbs sold at retail garden centers in the autumn. But then I saw splendid displays of these Iris growing at a local area botanic garden, so decided to give them a try. I like these Iris because they stand tall, and tidily neat, narrow, and spare of foliage, thus easily interjected into a planting bed without worry of overcrowding. The flowers are large, long lasting, and vibrantly colored. The bulbs are inexpensive, so I'll be trying lots more of these next year. Photo by Mark McDonough.
