Gardeners' Notes:

Positive DeenDixie On Apr 15, 2012, DeenDixie from Fayetteville, AR wrote:

This is probably my favorite iris germanica: beautiful bright true yellow color, several blooms per stem, increases for me yearly in my northwest Arkansas garden, rather mid to late season blooming. With several large blooms per stem, the wind and rain often knock it over, so I give it a prop with thin bambo poles cut to size.... which visually disappear into the landscape and do the necessary. I have asked my much younger brother to be sure to plant Well Endowed on my grave 50 years from now. :-)

Nice flower. Survived a long time (15-20 years) but never shown any propensity to increase. Typically get only 1-2 flower stems

This is a glorious blaze of sunshine for the garden! A wonderful, large golden yellow iris with long-lasting blooms. It can be seen from a long distance away. I have a ring of them around the base of a black walnut tree in an area where the soil is a bit dry, but they are thriving. I do water them in times of drought, but they haven't required any special care. Highly recommended!

A strong grower, blooms mid- to late May here (Nebraska, zone 5). Bright yellow, fades to cream right by the beard. I've seen it described as a rebloomer, but never had it rebloom for me.

My very first bearded iris, and a lovely one, at that! As a first timer, I've very pleased with growing irises. "Well Endowed" has an extremely eye-catching yellow bloom, and the straps themselves are a great addition to the flower bed.

Lives up to its name. Huge bright yellow flowers, each 8-9 inches long. Seems to have a shortened stem compared to other tall iris. Dependable bloomer. Definately one of my favorites, and about the best clear bright yellow available.
