Unlike other Pacifica iris species, Iris munzii grows slowly as large, robust plants with long, broad leaves. It's also unusual in its tendency to produce several flowers on each stem. Often you can see buds, blossoms, spent flowers and developing seed capsules - all on a single stalk. The first of the two photos below, taken in Sequoia National Park in Tulare County, California, shows this especially well.
The copy of Brian Collins' photograph on the right, of an Iris munzii growing in the Kew Royal Botanic Garden in London, shows us two stalks - each with multiple flowers in different stages of development.
