As its name suggests, the Cold Storage House is used mostly for storing plants and controlling their growth with cool temperatures, as florists might use refrigeration to prolong bloom. Bulbs being forced for the Spring Bulb Show and chrysanthemums being trained on wire for the Fall Mum Show can often be found here. More permanent residents include a eucalyptus tree (Eucalyptus beyeri) and showy coralberry (Ardisia crenata).
