All About Caladiums

Also known as Heart of Jesus, Angel Wings, Elephant Ear (not to be confused with Colocasia), and Arum Lilies, Caladiums belong to the Araceae family. These foliage-focused plants produce modest, spathe-like blooms in summer, but it's their leaves that steal the spotlight.

Caladiums naturally grow in rainforest understories and riverbanks, where humidity and dappled light help them flourish. The plants go dormant during extreme heat and dry seasons, which gardeners in colder zones should mimic for successful winter storage.

Their colorful leaves appear in speckled, splashed, or marbled patterns in every combination of green, white, red, and pink. With coarse yet delicate texture, Caladiums make excellent contrast plants in the shade garden.

How To Grow Caladium

Wear gloves when handling Caladium because they have a sap that can be a skin irritant to some people.

Light Needs:

Hot Climates: Full shade is preferred to prevent leaf scorch and fading.
Cool Climates: Partial sun (4+ hours) helps develop deeper colors.
Indoors: Caladium prefers bright indirect light but not direct sun.

Soil & Location:

Choose well-draining, rich, organic soil that retains moisture but never stays soggy.
A layer of arborist mulch helps conserve moisture and keeps the roots cool.

Watering:

Water deeply and regularly, especially in hot weather, keeping soil moist but not soggy.
Use the Finger Test to check for moisture before watering again.
If stressed by heat or drought, Caladium may enter early dormancy.

Planting Caladium Corms

When to Plant: After the danger of frost has passed in spring, or start indoors a few weeks earlier.
Optional Prep: Soaking corms overnight may speed up sprouting.
Which Side is Up? Plant the 'eyes' (bumpy side) facing up, roots down; though they'll grow either way if unsure.
Spacing: 5-10 inches apart, depending on how lush you want the display.
Depth: About 2 inches below the soil surface.
Fertilize: Add a balanced bulb fertilizer at planting and periodically through summer.

Foliage may begin to appear within 2-3 weeks. As leaves grow, trim away any that become yellowed or tattered to encourage new, healthy growth.

Growing Caladium Indoors & Out

Caladiums shine as seasonal houseplants and patio companions. Use them as thrilling centerpiece plants in containers with trailing vines and filler flowers. They're fantastic in covered porches, balconies, sunrooms, and even shaded entryways.

Indoors, they thrive in well-lit areas out of direct sunlight. In colder zones, bring container Caladiums inside before the first frost or lift the corms to store for winter.

Lifting Caladium In The Fall & Winter Storage

In colder climates, you can dig up Caladium corms to store for the winter and replant next spring. Even Caladiums growing as houseplants will naturally enter a resting period.

Once all foliage has died back in the fall, dig up your corms and store them as you would Canna and Dahlias.

Properly store Caladium corms by removing excess soil and letting the corms dry out in a location with good air circulation (can take 2 weeks or so, depending on relative humidity). Trim off excess leaves, stems, and roots at this time. Store in a cool, dark location 60°F or warmer for the winter. You can wrap the corms in a brown paper bag, cardboard box, or crate that has holes for air circulation, packed or wrapped loosely in newspaper, or shredded paper.

Growing Season Care Tips For Caladium

Once your Caladiums are up and growing, they'll reward you with months of vivid foliage, so give them the TLC they deserve!

Moisture is key. Keep soil consistently moist but not soggy. During hot spells, check daily and water deeply if needed.
Feed regularly. Use a balanced liquid or slow-release fertilizer every few weeks to maintain vibrant leaf color and lush growth.
Watch the light. Too much direct sun can cause browning or fading, so stick to dappled light or morning sun with afternoon shade.
Clean and tidy. Snip off any yellowed or damaged leaves to encourage fresh new growth and keep your plants looking their best.

Landscaping With Caladium

Caladiums are dazzling foliage-forward plants that create visual drama wherever they’re planted. With their bold colors and distinctive heart-shaped or strap-like leaves, they are excellent for layering, accenting, and brightening dim spaces in your landscape.

In the Shade Garden:
Tuck Caladiums beneath trees, alongside shade-loving perennials, or along the north-facing side of buildings where the sun rarely reaches. Their vibrant hues break up the deep greens of the shade and bring needed sparkle under the tree canopy. These beauties add both fine and coarse textures that dance in the filtered light, making them standout groundcovers or showy underplantings.

As a Groundcover or Border Edging:
Low-growing Strap Leaf varieties are perfect for mass plantings, edging pathways, or filling out shady borders. Their colorful leaves carpet the soil and help reduce weeds, while offering nonstop interest from spring to fall.

Container Gardens & Planters:
The compact size and flamboyant foliage make Caladium the ultimate thriller in shady mixed containers. Plant in pots with trailing vines and low-growing fillers to create eye-catching porch and patio displays. They shine in window boxes, urns, and even hanging baskets. Move containers indoors before frost, or use them to jazz up your sunroom year-round.

Rain Gardens & Moist Areas:
Caladiums love moisture and thrive in areas with higher humidity or steady rainfall. Use them to highlight water features, pond edges, and Rain Gardens where their tropical vibe enhances the lush surroundings.

Porches, Balconies & Indoor Use:
Shady porches, balconies, three-season rooms, and patios become instant tropical retreats with a few pots of Caladium. Their airy leaves move with the breeze, softening hardscapes and adding welcome pops of pink, white, and red. Indoors, place near bright windows out of direct sunlight for a splash of color that feels like a warm hug from the tropics.

Caladium as Companion Plants:
Use them to camouflage leggy stems of taller perennials and shrubs, or let them flank focal points like statues, benches, or water urns. Their bright patterns also complement green-leaved plants beautifully and help guide the eye through the garden.

With so many varieties and growth habits to choose from, Caladiums fit into every landscape style, from cottage and tropical poolside themes to modern and woodland designs.

Frequently Asked Questions

Do caladiums grow better in shade or partial sun?

It depends on your climate. In hot regions, caladiums perform best in full shade, where their leaves stay vibrant and resist scorching and fading. In cooler climates, partial sun with at least 4 hours of light per day actually helps develop richer, deeper leaf colors. Match your light conditions to your climate, and always protect caladiums from harsh afternoon sun regardless of where you garden.

Can caladiums survive full sun, or will they burn?

Caladiums can tolerate some sun, but their success in direct light depends heavily on your climate. In hot regions, full sun will scorch and fade their leaves, so full shade is strongly recommended. In cooler climates, partial sun of at least 4 hours per day can actually deepen leaf color and improve vibrancy. To protect your plants, site them in dappled or filtered light and use a layer of arborist mulch to keep roots cool and moisture consistent.

Which caladium varieties handle more sun than others?

Some caladium varieties, particularly those with thicker, darker, or more deeply pigmented leaves, tend to tolerate more sun exposure than the delicate white or light-pink fancy-leafed types. Strap-leaf caladiums as a group are generally more sun-tolerant than their fancy-leaf cousins and hold their color better with several hours of direct light. In cooler climates, most varieties can handle 4 or more hours of morning sun, but in hot southern gardens (Zone 8 and warmer), even sun-tolerant types benefit from afternoon shade to prevent scorching and color fade. Browse the caladium selection at Nature Hills and look for varieties described as sun-tolerant, then pair them with afternoon shade in your hottest months for the best results.

How often should you water caladiums in summer heat?

Caladiums are thirsty plants in summer heat and need deep, consistent watering to keep the soil evenly moist but never waterlogged. Check soil moisture using the finger test by inserting your finger an inch or two into the soil, and water again as soon as the top inch begins to dry out. In peak summer temperatures, this may mean watering every one to two days for container-grown plants and two to three times per week for in-ground beds. Apply a layer of arborist mulch around the base of your plants to retain soil moisture, regulate root temperature, and reduce how often you need to water.

How do you keep caladiums looking their best through the season?

Caladiums thrive with consistent moisture, so water deeply and regularly throughout the growing season, using the finger test to confirm the soil stays moist but never waterlogged. In hot climates, keep them in full shade to prevent leaf scorch and color fading, while gardeners in cooler regions can offer four or more hours of partial sun to intensify leaf color. A layer of arborist mulch helps retain soil moisture and keeps roots cool during summer heat. Feed regularly with a balanced fertilizer and watch for early dormancy as a signal that your plants need more water or shade.

When should you plant caladium bulbs in spring?

Plant caladium corms in spring after all danger of frost has passed and soil temperatures have consistently reached at least 65 to 70 degrees Fahrenheit, typically from late April through May in most growing zones. In warmer zones 9 through 11, you can plant as early as March, while gardeners in cooler northern zones should wait until late May or even early June to be safe. To get a head start on the season, start corms indoors in containers 4 to 6 weeks before your last expected frost date and transplant them outdoors once conditions are warm enough.

Can caladiums grow in containers on a shaded porch or patio?

Yes, caladiums are excellent container plants for shaded porches and patios, thriving in the warm, humid conditions these spots provide. Choose a pot with good drainage holes and fill it with rich, well-draining potting mix that retains moisture without staying soggy. Water deeply and regularly, keeping the soil consistently moist, and apply a layer of mulch on top to help retain moisture and keep roots cool. For best results, place containers where plants receive bright indirect light or dappled shade, and bring them indoors before any threat of frost since caladiums are cold-sensitive tropical plants.

How do you store caladium tubers over winter?

Before the first frost, dig up your caladium corms carefully, brush off excess soil, and allow them to dry in a warm spot for about a week. Store them in a paper bag or mesh container filled with peat moss or vermiculite at temperatures between 50 and 60 degrees Fahrenheit, somewhere dry like a garage or basement. Avoid storing them in airtight containers or anywhere that drops below 50 degrees, as cold and moisture are the two fastest ways to lose your corms over winter. Come spring, once soil temperatures reach around 65 degrees, you can replant them and enjoy another season of bold tropical color.
