Iris ‘Lent A. Williamson’ is an evergreen herbaceous perennial with a spreading habit. It grey/ green leaves are lance shaped with entire margins and erect. Its flowers are violet and purple with a yellow beard and up to 10cm across. Its roots are rhizomes which aids its spread.
Introduced in 1918, Iris ‘Lent A. Williamson’ was created by Mr. E. B. Williamson, a banker of Bluffton, Indiana, who having discovered a particularly nice bloom in among the Iris plants, decided to cross it nearly every other variety there. He created nearly 500 different crosses until he finally produced what we now know as Lent A. Williamson when one chance cross finally produced a seed pod.
The etymological root of the binomial name Iris is from the Greek meaning ‘rainbow’, probably in reference to the many colours of their flowers. ‘Lent A. Williamson’ was in honor of E. B. Williamson’s father.
