Iris hollandica

("Dutch iris")

Iris hollandica

A great cutflower due to its very sturdy flower stalk, flower diameter (4" / 10 cm) and wide color assortment that includes several bi-colored varieties. Rich, well-drained soil is important and, while it is quite acceptable to leave the bulbs in the ground, there is a risk of disease. Available in both Fall (plant in moderate climates) and in Spring (plant in colder climates).

Iris is a genus of more than 250 species of flowering plants with showy flowers. It takes its name from the Greek word for rainbow referring to the wide variety of flower colors found among the various species. The two main basic types of iris are the bulbous ones (which we describe here) and the rhizomatous ones which are considered perennials (the most familiar being Iris germanica and Iris sibirica).
