Ficus Amstel King
There are a few varieties of long leaf Ficus (longifolia) with quite similar leaves, one of the better types being Ficus "Amstel king".
They like medium to high light, and need to dry out a little between waterings.
Younger specimens of the long leaf Ficus can appear quite shapeless, but as they mature, this improves and they develop more character. The fresh young leaves of Ficus "Amstel King" are particularly attractive.
This Ficus was photographed in Brentford, several years ago, and it is now twice the size.
