Caladium is a very decorative plant: it is particularly appreciated for its colorful, large and particular shaped leaves. Unfortunately, since it is a tropical plant, it is not easy to grow because it prefers mild temperatures and a high humidity rate. It can be used permanently to decorate interiors or inserted in the garden, in flower beds or borders, but only during the summer.
The Caladium x hortolanum It is a perennial tuberous herbaceous plant native to South America. It has long, slightly arched, fleshy and smooth stems, which lead to the apex large round or heart-shaped leaves, pointed, two-tone or tricolor, white, pink, red and green, with a size ranging from 25 to 60 cm, shiny and thin.
There are numerous hybrid species of caladium, so we can see caladio colored in various ways, usually with the edges and veins of contrasting colors with respect to the central part of the leaf page.
The colors of the leaves are more intense if the plant is grown in a bright place; a very acidic soil will cause leaves with darker and more decisive colors.
The caladium wants, during the vegetative period, a very bright exposure, but one must avoid direct sun.
Caladium x hortolanum love positions in partial shade or in full shade, as far as possible from direct sunlight which could ruin the leaves. They are very afraid of the cold, so they should be taken outside only in late spring and summer, the rest of the year they are spent indoors, in a bright and airy place.
If desired, these plants can be grown as the most common tuber plants, such as dahlias for example; therefore they can be planted in the open ground in spring, to create an exotic and particular flowerbed, in a shady place.
With the arrival of the cold the leaves will begin to dry out, you can then unearth the tuber, cut the now dry leaves, and store the plants in a dark and dry place, such as a fabric bag filled with peat and sawdust; the bags should be kept away from the cold winters.
