About Indian heliotrope
Heliotropium indicum, known in Cambodian as 'ប្រមោយដំរី' (elephant's trunk) due to its inflorescence shape, is a robust annual herb growing up to 1 meter tall. Its leaves are alternate, oval, and hairy, producing small white or lilac flowers in curved spikes. It's ideal for tropical gardens or as a ruderal plant in warm areas, adding a wild and exotic touch.
Native range
Tropical and subtropical Americas, including the Caribbean
Care tips
It prefers full sun to partial shade and well-drained soils, tolerating a wide range of conditions. Watering should be regular to keep the substrate moist, but avoid waterlogging, especially in warm climates. It doesn't require a specific substrate, thriving in poor or rich soils. A common mistake is underestimating its vigor and not controlling its spread, as it can become invasive under favorable conditions.
