The sleeping giant of Sumatra
Endemic to the rainforests of western Sumatra, the Titan Arum builds an underground corm that can weigh more than fifty kilos — the single store of all its energy.
It alternates years of one solitary leaf several metres tall with long dormancies, until the bloom releases, for a few hours only, a carrion scent that draws pollinating beetles.
"The Titan Arum waits ten years to flower for a single night."
Styling Tip 01
Filtered light
Give it bright but filtered light, as under a forest canopy: direct sun scorches its single leaf within hours.
Styling Tip 02
Weekly watering
Water once a week while it is growing, then stop completely as soon as the leaf yellows and dormancy begins.
Styling Tip 03
Warmth and dormancy
Keep it at 25–30 °C with high humidity, and let the corm rest dry for several months before growth resumes.
