Caladium Flowers

Caladiums are plants that are native to South and Central America and are known for their colorful leaves that are heart-shaped. These plants are tropical to sub-tropical perennials and grow in wet and dry seasons. These plants belong to the Araceae family. Other common names for Caladium include angel wings and elephant ears. This plant dates back many centuries and is used for many years due to its colorful foliage that is truly eye catching. Its cultivation started in the 1700’s in Europe. Mostly, these plants are used as house plants or summer bedding plants.

Features of Caladium Flowers

The leaves of the Caladium plant have distinguished midribs with contrasting margins and many different types of patterns like veined or striped. They can be found in many shades of green, pink, white, and red. This plant is known to have no stems. The leaves are borne on elongated petioles that rise directly from underground tuber. A noteworthy fact about these plants is that blooming is not very common for them. If planted in favorable locations, these plants do tend to produce some flowers but only small ones.

These flowers are arum type flowers that are greenish pink and white towards the center. Caladium plants have their own different charm and also smell very pleasant. There are conflicting views on these small caladium flowers. Certain people believe that these flowers should be pinched off in order to help give more energy to the tubers whereas others believe that the small blooms should be left there as they have no effect on the whole plant.

These plants love the shade and can burn if they are planted in areas where there’s a lot of sunlight. Well-drained soil is ideal for the growth of these plants, especially in winter. This plant thrives in the warm season and tends to get dormant as soon as the weather becomes chilly.

Types of Caladium Plants

There are mainly two different types of Caladium plants:

Fancy Leaved Caladium Plants

A heart shaped Caladium leaf

The first one is the fancy leaved plant that has large heart shaped or semi heart shaped leaves on long petioles that are approximately 12 to 30 inches in height.

Strap Leaved Caladium Plants

A narrower Caladium leaf

The second type is characterized by shorter and narrower leaves that are strap or lance leaves with ruffled edges and are borne on short petioles. These have a height of less than 12 inches typically. This second type has more leaves that the first time per tuber, which gives the plant a fuller appearance.

Planting Caladiums

It is best to plant caladiums in warm and humid areas and in hardiness zones 8 and 9. The tubers should be planted directly into the ground in the spring season. The growing time for these plants can be saved by transplanting potted plants that are already growing. In order to make the fertilizing and watering process simpler, it is best that three tubers are planted in 6 inch pots and they are watered up to their rims in the beds. This helps to hold and store the water, which can stave off invasions and thirsty roots, making it easier for the tubers to lift up.

Caladium Plant Care

Regular fertilizing of these plants is needed to keep them healthy and growing, owing to the fact that this plant is basically all leaves. In order to keep new leaves coming up, it is essential that the plant is fed with a balanced soluble fertilizer around two to three times a month. These plants need supplemental water in order for the soil to be moist enough, especially in the hot summer months. If the Caladium is pot grown, they can be moved around to keep them warm. In the chilly weather, these plants should be kept near a sunny window till the leaves start withering. When they start withering, it is best that they are left to dry out completely. In order to save some space, the tubers should ideally be collected and stashed in an old hosiery or mesh bag and kept there for up to 5 months. If they are stored at over 60 degrees Fahrenheit, they can be planted the next spring, and be just as fresh.

There can be pest problems with these plants, specifically in the northern areas. By proper storage and proper planting procedures, tuber rot can be avoided to quite a good extent. If fertilizer is left on the leaves for too long, the leaves can burn.
