Afterwards store in a box or sack with sphagnum moss or vermiculite in a frost-free area until replanting in spring. Caladium forms a true tuber or enlarged underground stem. New tubers grow from the side of the original one. This plant is cherished for its foliage rather than its flowers. With its vivid foliage colors of red, pink, green, and white, it will brighten the darkest spots in the garden.
Many varieties are available with contrasting leaf venation colors and patterns.
Plants generally stay 12-18 inches tall. Caladium prefers a shaded site with moist soil and protection from strong winds. When the foliage dies in the fall, gently lift the tubers and dry them for a couple of weeks. Store the tubers in dry sand, vermiculite, or sphagnum moss in a cool, frost-free area. Gladiolus corms form immediately above the old corm.
