How are Caladiums measured?
Caladiums are graded by size, according to the circumference of the bulb. The greater the circumference, the more food that's stored inside. A #1 caladium bulb will produce a fuller plant with more stems and more leaves than a #2 bulb.
Planting high quality, grade #1 caladium bulbs, will give you better results and let you enjoy a better-looking garden.
