A rhizome is an underground stem that shoots out roots and shoots from its nodes, and this is how we sell our rhizomes.

A plant uses the rhizome to store starches, proteins, and other nutrients. These nutrients become useful for the plant when new shoots must be formed or when the plant dies back for the winter.

As soon as you receive them! They can remain dormant in cool temperatures until the spring temperatures stimulate new growth.

NOID indicates "no identification", as in not a named variety. We are proud to offer a wide selection of irises both named and unnamed, as we prioritize the beauty of the flower.

TB stands for "tall bearded", which is a characteristic of the most commonly found garden iris, bearded German Iris (I. germanica) and its numerous cultivars. Tall bearded iris begin blooming in early May in most parts of the US, and continue through mid-summer, depending on weather. Some of our rebloomers set their final blooms in August (Zone 9)! Tall bearded iris range in height from 28" to 48"!
