About Caladium 'Florida Sweetheart'

Caladium bicolor 'Florida Sweetheart' · also called Florida Sweetheart Caladium · houseplant

Caladium 'Florida Sweetheart' is a compact strap-leaf caladium with ruffled rose-pink leaves edged in a deep green band. Bred to take more sun and stay tidy, it forms a dense mound of colourful foliage in warm, humid, brightly lit spots through the growing season before retreating to a dormant tuber for winter.

Mature size: About 25-40 cm tall and wide; notably compact for a caladium, good for containers and edging.

Watch for — Brown leaf edges: Low humidity or inconsistent watering; raise humidity and keep the soil evenly moist in growth.

Indoor size vs how big it gets in the wild

Caladium 'Florida Sweetheart' is a naturally small plant — it stays shelf- and desk-sized for its whole life, so it never becomes a space problem. Indoors and in a pot, expect about 25-40 cm tall and wide. In the ground with no restriction it is a completely different plant — notably compact for a caladium, good for containers and edging. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Growth rate and years to mature

Caladium 'Florida Sweetheart' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: feed every 2-4 weeks during the growing season with a balanced liquid fertiliser at half strength to sustain the colourful foliage. stop feeding as the plant enters dormancy in late summer/autumn and resume when new leaves appear in spring.
