Thanks very much Oron, it is good to get this named. At the risk of acquiring pest status yet again, here are one or two more puzzles we have locally ! I think the pink flowered thistle is perhaps a Galactites ? and the Tradescantia with an enormous pink flower head is a great plant for under the shade of carobs, the prickly shrub is flowering at the moment,
as always, any and all comments gratefully received. Best wishes from the Algarve.
