This has been on the market since ’09 and is a revolutionary breakthrough in bittersweet culture. Bittersweet is one of those vines that require both a male and female plant—but not this one! Autumn Revolution has complete flowers, meaning the flower has both male and female parts! For whatever reason, the berry is twice the size of the species and the fruit production is extraordinary and prized by florists—the florists who saw this vine were awestruck. The berries retain their color when cut and used in dried arrangements. This is a very hardy vine suitable for all parts of Wyoming. Great screening vine!
