I would like to know what this plant is, please. It was photographed
in the hills of Sintra in Portugal last October. It is hummocky and
bush-like but not very tall. I am thinking some sort of Anthemis but
not at all sure. I am growing a number of seedlings from it but it
may be years before it flowers.
