Introduction to Caladiums
Caladiums, originating from South America, are perennial plants known for their striking foliage. They are a fantastic choice for both garden beds and indoor plant collections. Their leaves, often resembling the shape of a heart, come in a variety of colors and patterns, making them a popular choice for adding a decorative touch.
Types of Caladiums
Fancy-leaf vs. Strap-leaf Varieties
Caladiums are generally categorized into two main types: Fancy-leaf and Strap-leaf.
- Fancy-leaf Caladiums: Known for their large, heart-shaped leaves, these are perfect for making a bold statement. They come in a range of colors from white and pink to deep red.
- Strap-leaf Caladiums: These have more elongated leaves and are ideal for smaller spaces or as border plants in gardens.
| Variety | Leaf Shape | Ideal Use |
| Fancy-leaf | Heart-shaped | Statement pieces |
| Strap-leaf | Elongated | Borders and small spaces |
Ideal Growing Conditions
Caladiums are not just about good looks; they’re about finding the perfect spot to thrive. They prefer a warm climate, slightly acidic to acidic soil (pH 5.5 to 6.5), and a balance of light and shade.
Climate and Temperature Preferences
These tropical beauties love warmth. They are most comfortable in temperatures that don’t dip below 70°F (21°C).
Soil Type and pH Requirements
A light, well-draining soil rich in organic matter is ideal for caladiums. They prefer a slightly acidic to acidic environment for optimal growth.
Light and Shade Requirements
While they can tolerate a range of light conditions, caladiums do best in partial shade. A spot that gets gentle morning sun and afternoon shade is perfect.
Planting Caladiums
Spring is the ideal time to start your caladium journey. You can choose to plant tubers or go for potted plants.
When and How to Plant Caladiums
- Tubers: Plant them about 2 inches deep in the soil, ensuring the more bumpy side (the top) is facing upwards.
- Potted Plants: Transplant them into your garden or a larger pot, depending on where you want them to flourish.
Starting Caladiums Indoors
In cooler climates, it’s a good idea to start your caladiums indoors. Plant the tubers in pots and keep them in a warm, bright spot. This head start can make a big difference in their growth.

Fertilizing Requirements
