Caladiums are a popular choice for gardeners looking to add striking foliage to their landscape. Known for their vibrant, heart-shaped leaves in shades of green, pink, white, and red, these plants are sure to draw attention in any garden. But if you’ve fallen in love with caladiums, you may be wondering: are caladiums perennials?
Understanding Caladiums
Caladiums, native to South America, belong to the Araceae family. These tropical plants are often grown for their dramatic and colorful leaves rather than for flowers. Their stunning foliage can create beautiful contrasts in a garden, especially when placed alongside more subdued greenery.
There’s a lot of confusion surrounding caladiums, particularly whether they’re annuals or perennials. The answer to this depends largely on your climate and how you care for them.
Caladiums as Perennials
Caladiums are technically perennials, but only in certain conditions. In their native tropical habitats, caladiums grow year-round and return each year from their tubers (underground storage organs). In these regions, they can be left in the ground over the winter, and they’ll spring back to life when the temperatures warm up.
If you live in USDA hardiness zones 9-11, which have mild winters and warm temperatures throughout the year, your caladiums can be treated as perennials. These zones are generally found in southern parts of the United States, including Florida, parts of Texas, and Southern California. In these areas, caladiums will naturally return each spring, provided they are protected from any sudden freezes.
Caladiums in Cooler Climates
For gardeners in cooler climates, where temperatures drop below 55°F (13°C) in the winter, caladiums cannot survive outdoors year-round. In these regions, they are treated as annuals unless special steps are taken to protect them. Once frost hits, the foliage will die back, and the tubers can easily rot if exposed to prolonged cold or wet conditions.
However, there is a way to preserve your caladiums if you’re in a cooler zone. Many gardeners dig up their caladium tubers in the fall before the first frost and store them indoors over the winter. Here’s how:
Digging Up the Tubers: Once the foliage begins to die back, gently dig up the tubers. Be careful not to damage them.
Cleaning and Drying: Remove any excess soil and let the tubers dry for a few days in a cool, shaded area. This helps to prevent rot during storage.
Storing the Tubers: Store the dry tubers in a cool, dry place, such as a garage or basement. You can place them in a paper bag, a box of peat moss, or even some sawdust to prevent moisture from building up.
Replanting in Spring: Once the temperatures warm up again in the spring (consistently above 60°F or 16°C), you can replant the tubers in your garden or in containers.
By taking these steps, you can treat caladiums as perennials even in cooler climates, enjoying their vibrant leaves year after year.
Tips for Growing Caladiums Successfully
Whether you live in a tropical zone or a cooler region, here are some tips to ensure your caladiums thrive:
Location: Caladiums prefer partial shade or filtered sunlight. Too much direct sunlight can scorch their delicate leaves.
Soil: They grow best in well-draining soil with a high organic content. The soil should be kept consistently moist but not soggy.
Watering: Keep the soil evenly moist, especially during the growing season, but avoid waterlogging. Overwatering can lead to tuber rot.
Temperature: Caladiums thrive in warm temperatures and humidity. If the temperatures dip too low, growth will slow or cease altogether.
Fertilizing: Feed caladiums with a balanced, slow-release fertilizer every 6-8 weeks during the growing season for optimal growth.
caladiums are perennials in warm, tropical climates but must be treated as annuals in cooler regions unless you take steps to protect and store their tubers during the winter months. By following proper care guidelines, you can enjoy the stunning foliage of caladiums year after year, no matter where you live.
Whether you’re in the tropics or further north, caladiums are a beautiful and versatile addition to your garden that can bring a splash of color and interest to your landscape.

Landscaping with Caladiums
Caladiums are incredibly versatile plants that can be used in a variety of ways in your garden design. Here are a few ideas for incorporating them into your landscape:
Borders and Edging: Use caladiums to create colorful borders along walkways or garden beds. Their vibrant leaves can add a distinct visual separation between different areas of the garden.

Mass Plantings: For a striking effect, plant caladiums in large groups or masses. When placed together, their bright colors can make a bold statement and serve as a focal point in the garden.
Companion Planting: Caladiums can be paired with other plants that enjoy similar growing conditions. Consider combining them with hostas, begonias, or coleus to create interesting contrasts in both color and texture.

Frequently Asked Questions About Caladiums
As with any popular plant, gardeners often have a few common questions when it comes to growing and caring for caladiums. Here are some FAQs to help you get the most out of these beautiful plants.
Can caladiums grow indoors?
Yes! Caladiums can be grown indoors as houseplants, provided they receive bright, indirect light and a warm, humid environment. Just like outdoor caladiums, they prefer well-draining soil and consistent moisture. Keep them away from drafts or sudden temperature changes, and mist the leaves regularly to mimic the humid conditions they love.
Do caladiums bloom?
Caladiums are grown primarily for their stunning foliage, but they can bloom under the right conditions. Their flowers are relatively small and resemble the typical blooms of the Araceae family, including a spadix surrounded by a spathe. However, the flowers are not particularly showy and are often removed by gardeners to focus energy on the leaves.
Are caladiums toxic to pets?
Yes, caladiums are toxic to both cats and dogs if ingested. They contain calcium oxalate crystals, which can cause mouth irritation, drooling, difficulty swallowing, and vomiting in pets. It’s best to keep caladiums out of reach of curious pets to avoid any accidental ingestion.
How do I know when to dig up my caladiums for winter storage?
When temperatures begin to drop and you notice the foliage starting to yellow and die back, it’s time to dig up the tubers for winter storage. This typically happens in late fall before the first frost. Make sure to dig them up carefully to avoid damaging the tubers, as damaged tubers are more prone to rotting during storage.
How long do caladiums take to grow?
Caladiums typically take around 8 to 12 weeks to grow from tubers to full foliage, depending on the variety and growing conditions. They require warm temperatures to grow, so if you’re starting them indoors or planting them in cooler climates, be sure to wait until the soil has warmed up before planting.
What pests and diseases affect caladiums?
Caladiums can be affected by common garden pests such as aphids, spider mites, and snails. To manage these pests, you can use insecticidal soap, neem oil, or manual removal (in the case of snails and slugs). Caladiums are also susceptible to fungal diseases like leaf spot and tuber rot, especially if grown in overly wet conditions. To avoid these issues, ensure good air circulation around the plants, avoid overhead watering, and allow the soil to dry slightly between waterings.
Why Grow Caladiums?
Caladiums are a fantastic addition to any garden because of their ease of care, stunning appearance, and versatility in design. Whether you’re looking for a plant that can thrive in shady corners or one that makes a bold statement in a container on your patio, caladiums fit the bill. Their wide variety of colors and patterns allows for endless design possibilities.
Plus, even if you live in a region with cold winters, storing and replanting caladium tubers is a simple task that rewards you with beautiful foliage year after year. For those in warmer climates, caladiums provide nearly effortless beauty with minimal maintenance.
By understanding the needs of caladiums and providing them with the right environment, you can enjoy their vibrant leaves and tropical appeal throughout the growing season. Whether you’re a seasoned gardener or just getting started, caladiums are an excellent choice for adding color and texture to your landscape or indoor space.
