These Chrysanthemums, one of the work-horses of the floral industry, are sprays which are called Pompons (or Pompoms), as opposed to the disbudded Mums we call China-mums that look like Pompoms. Stems should be cut cleanly and crisply and placed immediately into water. Any leaves that will be submerged should be removed. Chrysanthemums specifically, and compositae in general, generate a lot of ethylene and release a lot of bacteria and tissue into the water so it is recommended that water be changed every day, and must be changed and re-cut every other day. The flowers should be hydrated in a low sugar holding solution and preferably processed in the cooler.
