SKU: 1610 Candidum Caladium (Caladium bicolor 'Candidum') in 3.5 inch pots

Plant Features & Growing Information

• Growth Habit: Upright, clump-forming, tuberous tropical perennial producing large, heart-shaped leaves on slender, upright stems. Typically reaches 12–24 inches tall and 12–24 inches wide at maturity, depending on growing conditions. Plants develop a full, bushy appearance as multiple leaves emerge from the underground tuber.

• Foliage Color: Produces spectacular bright white to creamy-white leaves with prominent dark green veins and green margins. The intricate network of green veins creates a beautiful contrast against the luminous white leaf surfaces. Mature leaves are broad, heart-shaped, and slightly translucent, making them especially attractive in shaded locations.

• Bloom Color: Occasionally produces small, inconspicuous greenish-white to pale yellow-green flowers consisting of a central spadix surrounded by a modified leaf called a spathe. Flowering is uncommon in landscape settings, and the plant is grown primarily for its colorful foliage rather than its flowers.

• Bloom Time: Flowers may occasionally appear during summer, although blooming is irregular and not a significant ornamental feature. The foliage provides the primary display from late spring through fall.

• Fragrance: Little to no noticeable fragrance. Candidum Caladium is primarily valued for its striking foliage rather than scented flowers or leaves.

• Fruit Flavor: Not grown for edible fruit. If pollinated, flowers may develop small, berry-like fruits containing seeds. These have no culinary value or desirable flavor and should not be consumed.

• Culinary Uses: Not edible. Candidum Caladium is cultivated strictly as an ornamental foliage plant. Its leaves, stems, tubers, flowers, and fruits contain irritating calcium oxalate crystals and should never be used in cooking, beverages, or edible decorations.

• Medicinal Uses: Although certain plants in the Araceae family have histories of traditional herbal use, Candidum Caladium has no established safe medicinal applications. Its tissues contain potentially harmful calcium oxalate crystals, making ingestion unsafe. The plant should not be used in homemade herbal remedies or medicinal preparations.

• Possible Toxicity to Pets or Humans: Toxic to cats, dogs, horses, and humans if ingested. All parts of the plant contain insoluble calcium oxalate crystals, which can cause intense irritation of the mouth, tongue, lips, and throat. Symptoms may include excessive drooling, difficulty swallowing, nausea, vomiting, and swelling of oral tissues. Contact with plant sap may also cause skin irritation in sensitive individuals. Wear gloves when handling tubers or pruning foliage, and keep plants away from children and pets.

• Wildlife & Pest Resistance: Generally deer- and rabbit-resistant due to its irritating calcium oxalate crystals, although browsing may occasionally occur. Its foliage provides attractive ornamental cover in shaded gardens. Because flowering is uncommon, it is not considered a significant pollinator plant. Typically resistant to serious insect problems, although slugs, snails, aphids, spider mites, and occasional caterpillars may damage foliage. Excessive moisture can encourage fungal diseases and tuber rot.

• USDA Planting Zones: Generally hardy as a perennial in USDA Zones 9–11, although winter survival may vary depending on local temperatures and soil conditions. In Zones 3–8, Candidum Caladium is typically grown as a warm-season annual or its tubers are lifted and stored indoors during winter. Plants are extremely sensitive to frost and cold soil.

• Sun Preferences: Thrives in partial shade to full shade, ideally receiving bright, filtered sunlight or gentle morning sun. Although Candidum has better sun tolerance than some traditional Caladium varieties, prolonged exposure to intense afternoon sunlight can scorch its delicate white foliage. Shaded locations provide the best leaf coloration and overall appearance.

• Drought Tolerance: Low to moderate. Candidum Caladium prefers consistently moist soil during active growth and is not considered drought-tolerant. Prolonged dry conditions may cause wilting, leaf curling, browning, or reduced growth. Maintain even moisture without allowing the soil to become waterlogged.

• Soil Preferences: Prefers fertile, loose, well-drained soil rich in organic matter. Performs best in slightly acidic soil with a pH of approximately 5.5–6.5 but tolerates a broader range of soil conditions. Incorporating compost can improve moisture retention and soil structure. Avoid heavy, compacted, or consistently saturated soil.

• When to Prune: Requires minimal pruning throughout the growing season. Remove damaged, yellowing, or dying leaves as needed. More extensive foliage removal should occur in fall after the plant naturally enters dormancy.

• How to Prune: Use clean pruning shears to remove damaged or discolored leaves by cutting their stems near the base of the plant. Avoid removing healthy foliage unnecessarily, as the leaves produce energy needed for tuber development. In fall, allow foliage to yellow naturally before cutting it back. If lifting tubers for winter storage, remove remaining dried foliage after the tubers have cured.

• Growth Rate: Moderate to fast during warm weather. Plants develop rapidly once soil temperatures remain consistently warm, producing new leaves throughout the growing season. Growth slows significantly when temperatures drop below approximately 60°F.

• Landscape Uses: Excellent for shade gardens, woodland borders, tropical landscapes, decorative containers, patio planters, shaded walkways, and mass plantings. Its bright white foliage creates beautiful contrast against darker green plants and colorful flowering annuals.

Planting Instructions from a 3.5" Pot into the Ground

• Best Planting Time: Plant in late spring or early summer after all danger of frost has passed, when nighttime temperatures consistently remain above approximately 60°F and soil temperatures have warmed to at least 65°F. Caladiums thrive in warm soil and should not be planted outdoors while temperatures remain cold.

• Acclimate the Plant: If the plant has been grown in a greenhouse or protected environment, gradually introduce it to outdoor conditions over approximately 5–7 days. Begin with a sheltered, shaded location and gradually increase exposure to filtered sunlight and outdoor temperatures.

• Choose a Location: Select a planting site receiving partial shade to full shade, preferably with gentle morning sunlight and protection from intense afternoon sun. Choose a location sheltered from strong winds, which can damage the delicate leaves.

• Prepare the Soil: Loosen the surrounding soil to a depth of approximately 8–10 inches, removing weeds, rocks, and debris. Incorporate compost or other well-decomposed organic matter to improve fertility, moisture retention, and drainage.

• Dig the Hole: Dig a planting hole approximately twice as wide as the root ball and no deeper than the root ball itself.

• Remove from the Pot: Carefully slide the Candidum Caladium plant from its 3.5-inch nursery container, supporting the root ball to minimize disturbance. Avoid pulling the plant by its delicate stems or leaves. Gently loosen tightly circling roots if necessary.

• Position the Plant: Place the root ball in the hole with its upper surface level with the surrounding soil. Avoid burying the crown or lower stems too deeply, as excessive moisture around the base can encourage rot.

• Backfill: Fill the planting hole with the original soil, gently firming it around the roots to eliminate large air pockets without excessively compacting the soil.

• Water Thoroughly: Water deeply immediately after planting to settle the soil around the roots. Continue watering regularly during the first several weeks while the plant establishes its root system.

• Spacing: Space plants approximately 12–18 inches apart for a full, lush display. For larger specimens or more open plantings, allow approximately 18–24 inches between plants.

• Mulching: Apply approximately 1–2 inches of organic mulch around the planting area to conserve moisture, suppress weeds, and regulate soil temperature. Keep mulch several inches away from the crown to prevent excessive moisture accumulation.

• Watering After Establishment: Maintain consistently moist but well-drained soil throughout the growing season. Water whenever the upper inch of soil begins to dry. Plants may require more frequent watering during hot, dry weather, particularly in sandy soil or exposed locations.

• Fertilization: Apply a balanced, slow-release fertilizer at planting time according to label directions, or use a diluted, water-soluble fertilizer approximately every 3–4 weeks during active growth. Avoid excessive fertilizer, which can cause leaf damage or salt buildup.

• Early Growth: Plants may require several days to adjust after transplanting. Maintain consistent moisture and protect newly planted specimens from direct afternoon sunlight until their roots become established.

Overwintering & Seasonal Care

• Zones 3–8: Candidum Caladium is typically grown as an annual or its tubers are lifted and stored indoors for winter. Plants cannot tolerate freezing temperatures and should be protected before the first frost.

• Zones 9–11: Plants may survive outdoors as tropical perennials where soil temperatures remain sufficiently warm and freezing conditions are absent. Foliage may naturally die back during cooler or drier periods, with new growth emerging when warm conditions return.

• Spring Maintenance: Plant outdoors after the last frost when soil temperatures have warmed. Resume regular watering and fertilization as new foliage develops.

• Summer Care: Maintain consistently moist soil and protect foliage from intense afternoon sunlight. Remove damaged leaves as needed and monitor for slugs, snails, and other occasional pests.

• Fall Maintenance: As temperatures begin to cool, reduce watering gradually. When foliage starts turning yellow and declining naturally, prepare to lift the tubers for winter storage in colder climates.

• When to Lift Tubers: In regions where winter temperatures fall below freezing, carefully dig up the tubers when foliage begins to yellow in fall, preferably before a hard frost. Use a garden fork or shovel to loosen the soil around the plant without damaging the tubers.

• Cleaning the Tubers: Gently shake off excess soil without washing the tubers. Remove severely damaged or rotting portions and inspect for signs of disease.

• Curing: Place the tubers in a warm, dry, well-ventilated location out of direct sunlight for approximately 7–14 days. Allow remaining foliage to dry naturally before removing it.

• Winter Storage: Store cured tubers in dry peat moss, vermiculite, or wood shavings in a ventilated container. Maintain temperatures around 60–70°F, avoiding freezing temperatures and excessive humidity. Check periodically for shriveling, mold, or rot.

• Winter Dormancy: During dormancy, the tubers remain inactive and require little to no water. Avoid storing them in damp conditions, as excess moisture can cause decay.

• Spring Replanting: Once outdoor soil temperatures reach approximately 65–70°F, replant stored tubers in the garden or start them indoors several weeks before the last frost. Position tubers with their growing eyes facing upward and cover with approximately 1–2 inches of soil.

• Spring Regrowth: New shoots emerge as temperatures warm. Resume moderate watering when growth begins, gradually increasing moisture as foliage develops.

Additional Growing Tips

Candidum Caladium is especially beautiful in shade gardens, woodland landscapes, tropical borders, decorative containers, and colorful mass plantings. Its luminous white-and-green foliage pairs wonderfully with hostas, ferns, begonias, impatiens, coleus, elephant ears, and other shade-loving plants.

For a particularly dramatic display, plant several Candidum Caladiums together in groups of three, five, or more. Their bright white foliage creates a striking contrast against darker green plants and helps illuminate shaded garden spaces.

Garden Tip: Candidum Caladium is an excellent choice for brightening areas beneath trees, along shaded pathways, or near covered patios. Its large white leaves reflect available light, creating a beautiful glowing effect in low-light garden settings.

Important Growing Consideration: Although Candidum is more tolerant of sunlight than some other fancy-leaved Caladium varieties, it performs best with protection from intense afternoon sun. Consistent moisture, warm soil, and filtered sunlight encourage the healthiest foliage and most vibrant coloration.

Safety Reminder: All parts of Candidum Caladium contain irritating calcium oxalate crystals. Keep plants away from pets and children, wear gloves when handling tubers, and avoid using any portion of the plant for culinary or medicinal purposes.
