The breeders, Marty Schafer and Jan Sacks, have written:

"Striking yellow bitone with good form.

"Blooms for a very long time either by extended bloom period or pause and repeat. Beautiful clump presentation."

Note that with Siberian irises, rebloom means additional flower scapes rise in early summer shortly after the first flush of blooms. Unlike tall bearded irises, there is no fall rebloom.

Schafer-Sacks irises have been awarded 7 of the last 9 Morgan-Woods Medals, the highest award given to a Siberian iris by the American Iris Society.
