This guide explores everything about Caladium ‘Luang Pu Yim’ — from its signature appearance and growth habit to planting, care tips, and how to showcase its bold beauty in your garden or home.
Striking Foliage and Color Pattern
‘Luang Pu Yim’ is known for its brilliant red leaves edged in contrasting green margins, often with subtle pink or white veins. The foliage is heart-shaped and semi-translucent, glowing when light passes through it. The bold red center dominates the leaf, while the green edging provides definition and structure — a hallmark of many premium Thai caladium hybrids.
This variety belongs to the fancy-leaf caladium group, characterized by broad leaves and upright growth. Its showy foliage is grown purely for visual impact rather than flowers.
Growth Habit and Size
- Height: 18–24 inches tall
- Spread: 12–18 inches wide
- Form: Upright clump of broad, heart-shaped leaves
- Lifecycle: Grows from tubers, dormant in winter in cooler climates
‘Luang Pu Yim’ is ideal for bedding displays, shaded borders, or container gardens where its bold leaves can be admired up close.
Best Growing Conditions
Light
Prefers partial to full shade. Bright indirect light intensifies the red coloration, but direct midday sun can scorch the leaves. Morning sun or dappled light is ideal.
Temperature
- Thrives in warm conditions (70–85°F).
- Cold-sensitive; plant tubers only after soil temperatures reach 65°F.
Soil
- Loose, well-draining, humus-rich soil is best.
- A slightly acidic to neutral pH (5.5–7.0) encourages vibrant leaf colors.
Planting Caladium Tubers
- Timing: Plant in late spring or early summer once soil has warmed.
- Depth: 1–2 inches deep with the knobby side (eye) facing up.
- Spacing: 8–12 inches apart for a dense foliage display.
- Watering After Planting: Water thoroughly, keeping soil evenly moist during sprouting.
Watering and Fertilizing
- Watering: Maintain consistently moist soil — caladiums dislike drying out completely. Avoid waterlogging, which can rot tubers.
- Fertilizing: Use a balanced, slow-release fertilizer at planting and supplement with diluted liquid feed every 4–6 weeks during the growing season. Overfertilizing can reduce leaf color intensity.
Maintenance and Care
- Deadheading: Not required; grown for foliage, not blooms.
- Leaf Care: Remove yellowing or damaged leaves promptly to maintain a tidy appearance.
- Mulching: Apply organic mulch to help retain moisture and regulate soil temperature.
- Pests: Watch for snails, slugs, and occasional aphids. Control with hand-picking or natural deterrents.
Seasonal Care and Overwintering
In Warm Climates (Zones 9–11)
- Caladiums can be left in the ground year-round. Leaves may die back in winter but regrow in spring.
In Cooler Climates
- Treat as an annual or lift tubers in fall:
- Dig up tubers after foliage dies back.
- Dry in a warm, shaded area for several days.
- Store in peat moss or vermiculite at 60–70°F until replanting in spring.
Design and Companion Planting
‘Luang Pu Yim’ pairs beautifully with:
- Hostas or ferns – contrasting textures in shady beds
- Impatiens or begonias – complementary flowering companions
- Coleus – vibrant foliage combinations for bold tropical designs
- Elephant ears (Alocasia/Colocasia) – layered height for dramatic displays
Container Gardens
Perfect for decorative pots on shaded patios, balconies, or entryways. Combine with trailing plants like sweet potato vine for lush arrangements.
Indoor and Conservatory Growing
- Place in bright, indirect light near east- or north-facing windows.
- Maintain high humidity (50% or more) for best leaf quality.
- Water when the top inch of soil begins to dry; avoid standing water.
Why Gardeners Love It

- Perfect for shady spots where flowers may not thrive
- Compact yet bold — makes a statement in small gardens or containers
- Versatile use — indoors or outdoors, in beds, pots, or mixed plantings
