About Panama Queen

Aphelandra sinclairiana · also called Panama Queen, Coral Aphelandra · tropical

A spectacular large tropical shrub native to Panama, Costa Rica, and Nicaragua, producing dramatic spikes of vivid coral-orange bracts with fragrant pink tubular flowers beloved by hummingbirds. Growing to 3 m outdoors in frost-free climates, it makes a bold container specimen in temperate zones when given warmth, filtered light, and consistent moisture.

Preferred mix: Rich, moisture-retentive, well-aerated tropical mix

Watch for — Leggy growth and poor flowering indoors: Insufficient light is the primary cause. Move the plant to the brightest possible filtered-light position. Prune back leggy stems in early spring after any flowering period to encourage vigorous branching and compact habit. Cut back by up to one third.
