Psidium cattleyanum

Psidium cattleyanum or "Goyavier" is an invasive plants from China or Brasil which has been introduced in Reunion Island in 1818 as a decorativ plant for the garden. But because this plant grows fast it quickly invaded the island. Today it is very common to find this bush on the side of hicking paths. And usually when it is the season (between June and september) people go hicking and come back with big bags full of those little red fruits and make tones of marmalade and jelly. I would discribe the taste of it as sour and sweet.
