About Gru-Gru palm
Acrocomia aculeata, commonly known as Corojo or Macaw Palm, is a robust and spiny palm native to Tropical America. It grows to significant heights, developing a trunk covered in sharp spines, topped by a dense crown of pinnate leaves. It is ideal for large landscapes, parks, and as a striking solitary specimen where its imposing presence can be admired safely.
Native range
Central America, the Caribbean, and tropical South America
Care tips
This palm thrives in full sun exposure for optimal growth and tolerates a wide range of soils, as long as they are well-drained. Watering should be regular during warm months, but it can withstand periods of drought once established. Avoid waterlogging, as it is susceptible to root rot in overly wet conditions. A common mistake is planting it in high-traffic areas without considering its sharp spines, which can be dangerous.
