Name: Caladium bicolor ‘Thailand’s Light’
Etymology:
The genus name Caladium is derived from the Malay word “keladi” for tuberous plants. The specific epithet bicolor means “two-colored”. The meaning and exact origin of the cultivar name ‘Thailand’s Light’ are not clearly documented.
First description:
‘Thailand’s Light’ is a horticultural cultivar and has no separate botanical first description. The underlying species Caladium bicolor was scientifically described in 1800.
Origin / Distribution:
Cultivar. Caladium bicolor is native to tropical America and is widespread in the moist regions of Central and South America. There is no documented natural origin for the cultivar ‘Thailand’s Light’.
Location / Habitat:
The cultivar does not occur as a natural population. Caladiums prefer warm, moist conditions with bright, filtered light and a loose, well-drained substrate. During the dormant phase, the plant retreats into its tuber.
Description & Notes:
Caladium bicolor ‘Thailand’s Light’ is a striking, tuberous foliage plant with heart-shaped to slightly arrow-shaped leaves. The leaf blades show a variable pattern of rich green, delicate pink, and light, almost white areas. Particularly characteristic are the intensely pink main veins, which spread star-shaped across the leaf surface and form a strong contrast to the green margin and the finely speckled leaf areas.

For vigorous growth, ‘Thailand’s Light’ requires a warm, bright location with filtered light and consistent moisture during the growing season. A loose, humus-rich substrate with good drainage prevents waterlogging and protects the underground tuber. After the leaves naturally wither, the dormant phase begins, during which watering should be significantly reduced.
