Iris Hill


Visit Iris Hill on the east side of Powell Gardens for a display of this spring favorite, which happens to be the official flower of Kansas City.

Iris Hill was established by Dr. Norlan Henderson in the early 1990s. A retired botany professor from the University of Missouri at Kansas City, Dr. Henderson helped plant the gentle slope with meandering ribbons of flowers.

The collection includes more than 500 varieties named as winners of the American Iris Society's Award of Merit. In 2009, the collection was featured at a national meeting of the American Iris Society.

Today members of the local AIS chapter volunteer their time to care for this exceptional collection. Check back for updates on 2015's peak iris bloom (it's usually around mid-May). 

Did you know? The reeds for wind instruments like the clarinet come from the spectacular tall Variegated Reeds (Arundo donax 'Variegata'  and 'Shanghai') found in the Perennial Garden's Bold Border. Learn More »
