How to care for your Triostar
Everything you need to keep your Triostar healthy: watering, light, humidity, feeding, repotting and pruning.
Stromanthe sanguinea 'Triostar' is native to the humid tropical forests of Brazil, where it grows in the understory under conditions of constant warmth and humidity. Its foliage is a true fireworks display of color: each leaf is unique, painted with irregular brushstrokes of green, creamy white, and pink, while the underside displays a deep, luminous magenta. This plant demands particular attention to humidity and water quality, like its Calathea and Maranta cousins. In return for attentive care, it offers an unmatched chromatic spectacle that brightens even the dullest interiors.

60–80% Requires high humidity for best appearance. Daily misting or a humidifier is recommended. Without adequate humidity, leaf edges brown and curl.
Feeding and fertiliser
Every 30 days
Feed monthly during spring and summer at half strength. Light feeder — too much fertilizer causes leaf burn. Stop feeding in autumn and winter.
