I discovered this beauty growing in a corner bed of my new house. I had no idea what type it was before coming to DG and having several helpful members assist me in identifying my Wabash. Purple-based foliage is the key! I had to divide mine this summer because it was so huge that the middle was beginning to rot. Every division grew well. It also was spot-free when a newer hybrid planted 2 feet away got infected with iris leaf spot. Really beautiful plant.

'Wabash' was given to me by a friend. His neighbor was going to throw it away, which is how he got it. It has a striking beauty in my iris patch, makes the eye vibrate. The depth of the purple color of the falls is unmatched. Blossoms seem to last a long time. The capacity to spread is better than most of the other bearded irises I grow.
While researching information, I found that there is another iris closely resembling 'Wabash', but it can be discounted for the lack of the purple shading at the base of the fans.
I hope to never be without this May blooming beauty.

This is the most amazingly vigorous historic bearded iris I've ever grown. In abandoned gardens in my city, it has taken over entire swaths of ground; some of the clumps are several square feet. In my own garden, it's grown from a very small rhizome to a 2 foot wide clump since I planted it 21 months ago. This spring was its best yet, sending up three bloom stalks loaded with its distinctive flowers. The only down side, to me, is that it's the only historic bearded iris I've yet had to stake in my windy garden, as its bloom stalks are so tall compared to the main clump that they have a tendency to flop to the side if even one flower is open on them. However, it is so beautiful that I am perfectly willing to make this small effort. It's no wonder it is one of the most popular irises of all-time!
Received a piece of rhizome from a friend who said it was "a purple and white iris". Planted it in February and was pleasantly surprised with a tall bloom stalk that year (in partial shade). The flowers have a very pleasing crisp shape that the contrasting colors add too. It makes me smile.
WABASH: 1936, TB, E. B. Williamson: I had some difficulty researching this in the AIS Database as copied and pasted here in quotes and parenthesis: "(AWARD)/1939TB @1936/WILLIAMSON, M/40"/WHT S; BLUE F BORDERED WHT TD1940; A1938C; H1937C" DM 1940)" I feel honored it was named the same as the city of Wabash, Indiana, Wabash County, Indiana and the fabled Wabash River flowing through the state. Strong growth and bloom habits. Great colors!

Blooms better in partial shade than most. Small blooms by today's standards and historic, tailored form, but the vibrant colors make it stand out, even among modern cultivars. Recessive amoena, pod and pollen fertile.
