So Aloe vera (back) and Aloe saponaria (front). Thanks.
BTW, this was from a cemetry, and there where also large specimens of Pancratium maritimum with fruit having a size of a small-sized egg.
Actually I am of the impression that Aloe vera was originally not naturalised but a native plant. However it is likely that due to collection of this plant for its properties, it likely died out as a "true" wild plant, and possibly the ones that one finds wild (such as at Cirkewwa) may originally have been planted.
I think there is a thread about this plant on the forum.
The plant is tought to be an archaeophyte (has been on our islands from ancient times) but the photo taken is a naturalised one, and those singular specimen scattered around on the coast are in my opinion all naturalised. A true native population of Aloe vera should consist of hundreds (or thousands) of plants close to each other.
