About Caladium 'Red Flash'
Red Flash is a large Caladium cultivar with bold splashes of crimson-red radiating out from the central veins over a green blade, flecked with smaller pink and white spots throughout. It is one of the larger-leaved cultivars in the bicolor family, and like the rest of the family it is fully deciduous, dying back to its tuber each year.

Before you buy
- If buying a dormant tuber, check it is firm and plump, not soft, shrivelled or mouldy
- Confirm whether you are buying a live growing plant (in leaf) or a dormant out-of-season tuber
- Established leafy plants should show firm, unblemished foliage without scorch marks
Caladium 'Red Flash' care
- Substrate
- Light, free-draining mix: 50% potting compost, 30% perlite, 20% coco coir.
- Watering
- Keep evenly moist throughout active growth; stop watering almost entirely once the foliage dies back for dormancy.
- Humidity
- 55-75% preferred during active growth for the largest leaves.
- Feeding
- Balanced liquid fertiliser at half strength every 2-3 weeks during active growth; none during dormancy.
- Repotting
- Repot the dormant tuber into fresh substrate each spring when new growth begins.
Common problems
Tuber rot over winter
Cause: Substrate kept too wet during dormancy
Fix: Keep the dormant tuber nearly dry and store in a cool, frost-free spot until spring
No regrowth in spring
Cause: Tuber temperature too low, or tuber was damaged/rotted
Fix: Ensure the tuber is kept above roughly 18°C once you want it to resprout, and check it is still firm before replanting
Scorched or bleached leaves
Cause: Direct hot sun
Fix: Move to bright indirect light or light shade; most Caladium foliage scorches in direct summer sun
