I’ve been purchasing bulbs from A.D.R. for many years. The quality is superior and the service fantastic. Chris and his family have always been prompt and accommodating. If you need it, Chris can find it! I wouldn’t shop anywhere else!

Caladium 'Red Flash' is a bold, fancy-leaf variety with large, heart-shaped olive-green leaves adorned with brilliant red veining and pink freckles. More sun-tolerant than many caladiums, it thrives in partial shade to full shade and prefers humus-rich, moist, well-drained soil. Growing up to 24–36 inches tall, it makes a dramatic statement in shaded borders, containers, and indoor settings. In colder climates, tubers should be lifted and stored indoors before winter to ensure a fresh display the following season.

Planting: Wait until soil temperatures reach at least 70°F. Plant tubers 1 to 2 inches deep with the knobby side up.
Location: Prefers partial to full shade, though some newer varieties tolerate morning sun.
Soil: Loose, well-drained, slightly acidic soil (pH 5.5–6.5) enriched with compost or peat moss.
Watering: Keep soil consistently moist but not soggy. Avoid letting it dry out completely.
Humidity: Thrives in high humidity. Mist occasionally or group with other plants to boost moisture.
Temperature: Grows best between 70–85°F. Not frost-tolerant—plant after the last frost and lift tubers before the first.
Fertilization: Feed every 4–6 weeks with a balanced, diluted fertilizer during the growing season.
Pruning: Remove yellowing leaves and spent foliage to maintain appearance.
Pest & Disease: Watch for fungal issues, mealybugs, and aphids. Ensure good air circulation and avoid overhead watering.
Overwintering: In colder zones, lift tubers in fall, dry them, and store in a cool, dry place until spring.
