How to tell it
Thick three-sided leaves like green knives, on creeping stems metres long. Large showy flowers, yellow or magenta, opening only in sun.
What it is confused with
Sally-my-handsome
Carpobrotus acinaciformis
Two closely related invaders that hybridise. Acinaciformis has a large magenta flower and a more curved leaf; edulis has a yellow flower that ages pink. For practical purposes both are removed.
What it is for
The fruit is edible and used for jam in South Africa, but that is no reason to keep it here: it acidifies the sand, smothers native dune flora and breaks down the dune's structure.
Traditionally used as food. This is not permission to eat it.
The law says
An invasive alien species in Portugal. Do not plant or propagate it, and dune removal actions are done with authorisation and method.
