If you’ve ever tried growing caladiums in containers, you already know their colorful, heart‑shaped leaves can brighten even the shadiest corner of a home garden. But many beginners struggle with the next step: What to plant with caladiums in pots so the whole container looks balanced, healthy, and long‑lasting?
In my own balcony and backyard containers, I’ve tested dozens of pairings. Some plants wilt from too much shade, some fight for root space, and others simply don’t match caladiums’ need for steady moisture. But a handful of plants consistently perform beautifully with them.
This guide breaks down the most dependable, real‑world combinations simple enough for beginners, but professional‑looking enough for any garden.
Why Certain Plants Grow Better With Caladiums
Caladiums are shade‑loving tropical foliage plants that thrive in:
• Warm temperatures • High humidity • Fertile, well‑draining soil • Consistently moist conditions • Bright shade or filtered light
Because of this, the best companions are plants that:
• Prefer the same partial‑shade environment • Handle regular watering • Don’t compete heavily for root space • Offer contrasting shapes or colors
When you choose plants with matching needs, the container stays healthier with less work no scorched leaves, no constant drooping, no mismatched watering needs.
What Materials Actually You’ll Need
• Caladium tubers or potted plants • Large pot (at least 12–14 inches wide) • Rich potting mix with compost • Slow‑release fertilizer • Shade‑tolerant companion plants (list below) • Mulch (optional but helps with moisture)
Eco‑friendly options: • Homemade compost • Coconut husk mulch • Organic slow‑release fertilizers
Best Plants to Grow With Caladiums in Pots
1. Begonias
One of my most reliable combinations.
• Thrive in partial shade • Love moisture but not soggy soil • Continuous blooms add contrast • Compact growth fills space under caladium leaves
2. Impatiens
Perfect for beginners.
• Bright pops of color • Handle shade extremely well • Stay low and don’t smother caladium foliage
3. Coleus
Great foliage‑on‑foliage pairing.
• Huge variety of colors • Matches caladiums’ moisture needs • Works in shade or indirect light
Pro tip: Choose compact or trailing coleus for mixed containers.
4. Ferns
Soft texture balances caladiums’ bold leaves.
• Love the same humidity • Stay lush in shaded patios • Perfect for layered foliage arrangements
5. Sweet Potato Vine (Ipomoea batatas)
One of my favorites for edge‑of‑pot drama.
• Trails gracefully down the container • Handles shade surprisingly well • Comes in chartreuse, purple, and variegated types
6. Torenia (Wishbone Flower)
Ideal if you want blooms without sun stress.
• Shade‑loving annual • Continuous flowers across summer • Attracts pollinators in low‑light gardens
7. Heuchera (Coral Bells)
An excellent match for caladium color palettes.
• Handles shade • Beautiful contrasting foliage • Works well in larger containers
8. Browallia
My go‑to for blue flowers in shade.
• Compact and neat • Handles moisture • Looks especially good with red or pink caladium varieties
Step‑by‑Step: How to Assemble a Caladium Companion Pot
1. Choose the Container
Use a pot at least 12–14 inches wide. For multiple companions, 16–18 inches is better.
2. Fill With Rich, Moisture‑Retaining Soil
Mix:
• 60% potting mix • 30% compost • 10% coco peat or leaf mold
This keeps the soil airy but moisture‑steady.
3. Plant the Caladiums First
• Position caladiums toward the center or slightly back of the pot. • Tubers should be planted 2 inches deep, bumps facing up. • If using live plants, transplant gently their roots are sensitive.
4. Add Companion Plants
Use this simple formula:
• Thriller (height) – Caladiums • Filler (medium plants) – Begonias, impatiens, coleus • Spiller (trailing plants) – Sweet potato vine, trailing coleus
5. Water Thoroughly
Caladiums droop if even slightly under‑watered.
6. Place in Bright Shade
Direct sun for long periods burns their leaves, especially thin‑leaf varieties.
Expert Tips & Best Practices
• Water early in the morning helps prevent fungal issues. • Don’t pack too many plants caladium roots need room to expand. • Keep pots away from strong wind leaves tear easily. • Use mulch to maintain moisture in hot climates. • Rotate pots every 1–2 weeks to ensure even growth. • In very hot summers, increase watering frequency.
Common beginner mistake: Pairing caladiums with sun‑loving plants like petunias or marigolds they will scorch or stunt.

Caladiums simply can’t tolerate drought‑tolerant partners.
