Swiss Chard – Rhubarb Supreme



With bright red petioles, dark green leaves and an upright habit, Rhubarb Supreme Swiss Chard stands head and shoulders above its predecessor “Rhubarb”. The most significant improvement is in the reduction of early bolting plants, a trait that seems to affect red chard more than other types. Excellent for both bunching as well as baby leaf production. This highly anticipated release is a stellar example of “participatory plant breeding”: a process that involves input from both professional plant breeders and on-the-ground organic farmers. Nash Huber, of Nash’s Organic Farm in Sequim, WA worked with Dr. John Navazio and Organic Seed Alliance over many years to finesse this mighty chard into existence and we now all stand to benefit!
