Alocasia odora
(Araceae)
“Elephant’s Ear.” “Oreja de Elephante.”
Tropical Asia.
An impressive evergreen perennial growing from a strong rhizome, Alocasia thrives in partial shade and humidity, as here in the Park. The sagittate leaves can grow 1m long by 75cm wide. The unisexual flowers are small, without perianth, and are arranged in a compact spike (spadix) protected by a leaf like bract. There are many examples of single specimens and established clumps throughout the area.
View towards the pond area, Parque de Malaga.

What is the underplanting to the Alocasia’s..looks like Liriope ?
You identify the Alocasia’s as odora,I thought they were A. macrorrhiza [Elephants Ear plant]. Do you have a picture I could see of the edge of the circular pool?.it looks a very interesting double edge.
