Cigar Calathea

Calathea lutea is native to tropical Central and South America and the Caribbean.

• Distributed from southern Mexico through Central America to Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, and Brazil, as well as Trinidad and Tobago
• Found in lowland tropical rainforests, swamp forests, forest margins, and along riverbanks
• Occurs from sea level to approximately 1,000 m elevation
• Often found in wet, marshy areas and seasonally flooded habitats
• Prefers warm, humid conditions with consistent moisture
• First described by the French botanist Jean-Baptiste Lamarck and later transferred to Calathea by the German botanist August Wilhelm Eduard Theodor Henschel
• The species epithet "lutea" means "yellow," possibly referring to the yellowish tones of the bracts
• Widely cultivated in tropical gardens and as a utility plant for leaf material
• The large, silvery-backed leaves have been used traditionally by indigenous peoples for wrapping food and goods

A large, robust, rhizomatous perennial with massive paddle-shaped leaves.

Growth Habit:
• Erect, forming large clumps 2-3 m tall and 1-2 m wide
• Thick, fleshy rhizomes produce multiple upright stems
• Each stem bears a single large leaf and eventually terminates in an inflorescence

Leaves:\• Enormous, paddle-shaped to broadly ovate, 50-120 cm long and 25-50 cm wide
• Upper surface: dark green to grayish-green, matte to slightly glossy
• Lower surface: covered in a dense, silvery-white to grayish-white waxy coating (bloom)
• The silvery underside is the most distinctive foliar feature
• Leaves are held on long, stout petioles 30-80 cm long
• Like other marantas, leaves fold upward at night (nyctinasty)
• Margins are entire, sometimes slightly wavy

Inflorescence:
• The most distinctive feature: dense, cylindrical, cigar-shaped spikes 8-15 cm long and 2-3 cm in diameter
• Composed of overlapping, brown to reddish-brown bracts arranged in spiral ranks
• Bracts are stiff, papery, and persistent, giving the "cigar" appearance
• Inflorescences are borne on stout peduncles at the top of the stem
• Multiple inflorescences per stem

Flowers:
• Small, yellowish-white to cream, tubular, emerging between the bracts
• Relatively inconspicuous compared to the dramatic cigar-shaped bracts
• Pollinated by bees and other small insects

Cigar Calathea is an ecologically significant plant in tropical wetland and forest edge habitats.

• Occurs in wet, marshy habitats and along riverbanks, contributing to riparian vegetation
• Large leaves provide shade and habitat for understory organisms
• The silvery waxy coating on the leaf underside may help reflect excess light and reduce water loss
• Nyctinastic leaf movements may protect the photosynthetic apparatus from cold nighttime temperatures
• Inflorescences provide habitat for small insects and spiders within the bract layers
• Flowers produce nectar that attracts bees and other pollinators
• Rhizomatous growth helps stabilize wet soil and prevent erosion
• The species' preference for wet habitats makes it an important component of tropical freshwater wetland ecosystems
• Leaves decompose rapidly, contributing to soil organic matter in wetland environments
• Can form dense, nearly monospecific stands in marshy habitats

Cigar Calathea is relatively easy to grow in tropical and subtropical environments.

• Requires warm, humid tropical to subtropical conditions
• Tolerates temperatures as low as 5°C for brief periods but prefers temperatures above 15°C
• Highly adaptable to light conditions: grows in full sun to deep shade
• Best foliage color and vigor in partial shade to bright filtered light
• Requires consistently moist to wet soil; tolerant of waterlogged conditions
• Prefers rich, organic, loamy to clay soils
• Propagation is by division of rhizome clumps; each division should include roots and at least one growing point
• Can also be propagated by seed, though this is less common
• Very vigorous grower; space plants 1-1.5 m apart
• Fertilize regularly during the growing season for best growth
• Remove old or damaged leaves to maintain appearance
• Excellent for tropical landscaping as a specimen, hedge, or waterside planting
• Hardy in USDA Zones 9b-12
