 Caladium Bulb Sizes and Information



Bulb Sizes:
                 
Caladium bulbs are sold in various size grades based on the diameter of the bulb.  The bulbs are categorized into the following traditional sizes:

  • Mammoth:  3 to 4 (9.0 11.5 cm) - Offered Online when available
     

  • Super Mammoth or Colossal:    4 Up (11.5 cm) - Very Rare

A Note about bulb sizes vs. size of mature plant:
   Larger bulb sizes have more "food" for leaves to start. So  jumbo and larger bulbs will generally have more leaves sprouting at a faster clip and growing bigger sooner than cousins much smaller in size. However, the smaller bulbs will catch up as to leaf size and plant height eventually, most likely not as many leaves as the bigger bulbs.

Bulb Storage:            
Caladiums are tropical plants, and bulbs must be stored at temperatures above 60F (16C) with a relative humidity in the neighborhood of 75%. When storing caladiums, unpack them immediately upon arrival and store them in open trays with proper air circulation.  Exposing bulbs to cold temperatures manifests itself in stunted (sometimes very slow) erratic growth even though the bulb does not show any injury at all.
