Methods, devices and compositions to preserve plants, such as cut flowers. The methods include, e.g., sealing cut stems in antimicrobial preservative media, sealing the leaves in a substantially unvented compartment and sealing the flower blossoms in a less humid vented environment. Methods include, e.g., sealing cut flower ends in a preservative liquid, sealing the majority of the stem length and leaves in a stem compartment and holding the blossoms and at least a portion of the leaves in a relatively open blossom compartment. The devices include, e.g., packaging materials and preservative to vitalize and protect uprooted plants and / or cut flowers. The compositions of the invention provide, e.g., packaging systems and preservative media which inhibit microbe growth and vitalize cut plants.
