Caladium ‘Red Flash’

Caladium 'Red Flash' is a fancy-leaved caladium valued for large, heart-shaped foliage with dark red coloring, pink spotting, and wide dark green margins. It is a warm-season, tuberous plant in the Araceae family.

Give Caladium 'Red Flash' bright filtered light to partial shade. It can tolerate some gentle morning sun, but intense afternoon sun may scorch or fade the leaves.

Water Caladium 'Red Flash' whenever the surface begins to dry, keeping the soil evenly moist but never waterlogged. Reduce watering when the plant naturally enters dormancy.

Caladium 'Red Flash' commonly reaches about 18 to 30 inches tall, with large leaves and an upright growth habit. Mature size depends on tuber size, warmth, light, nutrition, and growing conditions.

Yes, Caladium 'Red Flash' can grow indoors near a bright window with filtered light and warm temperatures. Keep it away from cold drafts, heating vents, and harsh direct afternoon sun.

Caladium 'Red Flash' may tolerate more sun than shade-oriented caladiums, but partial shade is safer in most U.S. gardens. Strong afternoon sunlight, especially with dry soil, can burn the foliage.

Caladium 'Red Flash' grows best in warm conditions, roughly 70–85°F during active growth. Protect it when temperatures approach 55°F and never expose the tuber or foliage to freezing temperatures.

You can grow Caladium 'Red Flash' outdoors year-round only in reliably frost-free areas, generally corresponding to warm USDA climates. In colder regions, grow it as a seasonal plant or overwinter the tuber indoors.

Yes, Caladium 'Red Flash' performs well in containers filled with moisture-retentive but well-drained mix. Choose a pot with drainage holes and avoid using a container much larger than the root system.

Brown leaves on Caladium 'Red Flash' are commonly caused by intense sun, dry soil, low humidity, cold exposure, or fertilizer buildup. Move it to filtered light, restore consistent moisture, and check that the pot drains freely.

Caladium 'Red Flash' may droop when the soil is too dry, temperatures are too cold, or the tuber is beginning seasonal dormancy. Check soil moisture and temperature first, while recognizing that natural fall dieback is normal.

Leaf loss is normal when Caladium 'Red Flash' enters dormancy as days shorten and temperatures cool. If it is actively growing, sudden leaf loss can indicate cold stress, root problems, severe dryness, or overwatering.

Use a moisture-retentive, organic-rich, well-drained loam or container mix for Caladium 'Red Flash'. The soil should hold steady moisture while allowing excess water to drain quickly.

Yes, light regular feeding during active growth can support the large foliage of Caladium 'Red Flash'. Use a balanced fertilizer at the label’s diluted rate and stop feeding when the plant enters dormancy.

Prevent root rot by using porous, well-drained soil, a pot with drainage holes, and consistent rather than excessive watering. Never leave the container standing in a saucer of water.

Caladium 'Red Flash' can attract common foliage pests such as aphids, mealybugs, spider mites, and thrips. Inspect the undersides of leaves regularly and address infestations promptly with an appropriate treatment.

Plant Caladium 'Red Flash' outdoors after the last spring frost, when the soil is consistently warm and nights remain above about 55°F. Cold, wet soil can delay sprouting or encourage tuber rot.

Plant Caladium 'Red Flash' tubers about 1½–2 inches deep with the buds or eyes facing upward. Space plants roughly 8–12 inches apart, adjusting spacing for the desired fullness.

Caladium 'Red Flash' commonly takes several weeks to sprout after planting, especially if soil temperatures are cool. Warm soil, even moisture, and patience are more helpful than repeatedly disturbing the tuber.

Yes, start Caladium 'Red Flash' indoors in a warm container of lightly moist, well-drained mix several weeks before outdoor planting. Move it outside gradually after frost danger has passed and temperatures are warm.

Propagate Caladium 'Red Flash' primarily by dividing its dormant tuber into sections, with each section retaining at least one healthy eye. Allow cut surfaces to dry briefly before planting divisions in warm, lightly moist mix.

No, ordinary leaf cuttings do not reliably produce new Caladium 'Red Flash' plants. Division of the tuber is the practical method for maintaining this named cultivar.

Removing the dominant central eye can encourage a shorter, fuller plant with more evenly distributed shoots. It is optional, and leaving the eye intact usually produces a taller plant with stronger central growth.

Routine pruning is not needed for Caladium 'Red Flash'; remove only yellow, damaged, or completely dead leaves at the base. Avoid cutting healthy foliage because the leaves help replenish the tuber.

Before freezing weather, allow the foliage to die back, lift the tuber, and store it dry in a warm, frost-free location, ideally around 60–70°F. Replant in spring only after the soil has warmed and frost danger has passed.

Yes, Caladium 'Red Flash' is toxic to dogs and cats because it contains insoluble calcium oxalate crystals. Chewing it can cause painful mouth irritation, drooling, vomiting, and difficulty swallowing, so keep it away from pets.

Yes, Caladium 'Red Flash' can irritate the mouth, throat, and digestive tract if chewed or swallowed because of insoluble calcium oxalate crystals. Keep it away from children, and seek poison-control or medical advice after ingestion.

Caladium 'Red Flash' can produce small, inconspicuous, calla-like flowers, but it is grown primarily for its colorful foliage. Flowering is not guaranteed and may be reduced indoors or under stressful conditions.
