Another type of bulbous Iris that does very well in my garden are Dutch Iris (Iris x hollandica cvs.).
Despite the Latin name, Iris
is not a natural hybrid, nor is it native to the Netherlands. Rather, it is a cross between several different species of Iris
native to southwestern Europe and northwestern Africa, most notably Spanish Iris (Iris xiphium)
and Tangiers Iris (Iris tingitana
). Dutch Iris cultivars ar enow available in wide array of colours and patterns. They are widely grown, both as garden ornamentals and as cut flowers for the florist trade. Being descended from species native to Mediterranean climates, Dutch Iris go dormant in late Spring after blooming. During Summer, the dormant, underground bulbs should be watered as little as possible, though they do tolerate occasional light irrigation in my garden.
