Lifeway Foods Inc., Morton Grove, Ill., released a limited-edition spring flavor — Hibiscus Rhubarb Pie Kefir — along with its first label design collaboration. Created by renowned fashion designer Cynthia Rowley and featuring bold floral patterns from the brand’s Rowley fitness collection, the kefir flavor and designer label combination gives Lifeway a one-of-a-kind package, said the company.

The Hibiscus Rhubarb Pie Kefir was inspired by a gardeners’ harbinger of spring — rhubarb, as well as the inventive new usages of hibiscus by chefs and culinary trendsetters. The flavor will be available in stores nationwide through the beginning of summer.

“This collaboration is a fresh way to integrate the components of a healthy lifestyle across multiple platforms,” says Lifeway CEO Julie Smolyansky. “Both Lifeway and Cynthia Rowley inspire people to live healthier, stronger and empowered lives. ”

The company also has its limited-edition Watermelon kefir that hit stores in March and is available through the summer.
