Arno Nehrling Caladium Bulbs | Sun-Loving Pink Fancy Leaf Tropical Foliage

A Sun-Tolerant Pink Beauty That Gets Better With Age

Arno Nehrling (also listed as Mrs. Arno Nehrling) is a classic fancy-leaf caladium prized for its sun-loving nature — a rare trait among caladiums. Its large, heart-shaped leaves are a soft pink variety with a narrow dark green border and vivid crimson-red veins, and the color continues to evolve and deepen as the plant matures, making it a dynamic, season-long performer. At 18–24 inches tall, it’s equally at home in sunny borders and large containers.

Plant Highlights

• Leaf type: Fancy leaf — large, heart-shaped
• Colors: Pink with narrow dark green border and crimson red veins; color deepens with maturity
• Height: 18–24 inches
• Light: Sun to partial shade — one of the most sun-tolerant fancy-leaf caladiums
• USDA Zones: 9–11 (lift tubers in fall in colder zones)
• Great for: Sunny borders, containers, garden accents, potted plants
• Thrives in: Heat and humidity

How to Plant Caladium Bulbs

Plant tubers knobby side up, 1–1½ inches deep and 8–14 inches apart. Wait until soil temperature is consistently above 65°F before planting outdoors. Removing the main bud before planting produces a fuller, leafier plant.

Care Tips

• Soil: Warm, fertile, moist, well-draining mix
• Water: Keep consistently moist; avoid waterlogged, cool soil
• Light: Favors sun to partial shade — more sun-tolerant than most fancy-leaf varieties
• Dormancy: Goes dormant in prolonged dry weather; nearly evergreen in warm, moist conditions
• Winter storage: In zones below 9, dig tubers in fall and store in a dry, airy place until spring

Arno Nehrling is an excellent choice for gardeners who want the lush beauty of a fancy-leaf caladium in a sunnier location — one of the few varieties that genuinely thrives in more light.
