Many plants sold as Dietes irioides are actually Dietes grandiflora. D. grandiflora has dark, brownish markings on the inner tepals but D. iridioides does not.



A very special "thank you" to Evan for posting the photos!

This is an easy care plant which performs & performs. It is one you don't need to provide much care for. After establishing; it takes care of itself. Drought hardy doesn't begin to describe it & you are rewarded with these beautiful flowers. When not in bloom the foliage is pretty too. I have found zero pest or disease problems with this plant.

Do NOT remove the stem that bloomed as it will bloom next year. Each stem blooms for multiple years.
