I saw a great photo in one of my old Bell'Italia magazines (I can't part with them) and now, almost fifteen years later, I found this photo (not the same as the one in the old magazine) online re the area:
This is at Parco Punto Falcone, which is between Livorno and Grosseto on the Tuscan coast, right near Piombino. Nature may have had a hand here, re wildflowers, but I'm not sure on that.

The writer says - "You get a great view from here of the ferries passing each other on the way to and from the Isola d'Elba, which sometimes feels so close that you could almost touch it.
Amongst its carpet of pink of Sour Figs or Cistus incanus (locally known as Cistus Villoso), are the creamy-white flowers of the low growing bushes of "Barba di Giove" - Beard of Zeus (Anthyllis barba-jovis), once used for healing wounds.
Yellow gorse, wispy pink thistles, and yellow daisies (I'm still trying to find out their name a I didn't photograph the tags - the park authorities have helpfully put name labels on the plants along the coastal pathway) growing amongst the rubble of broken pillow lavas.
If you visit in April, this is what you will see."
(I didn't find the writer/photographer's name to give a credit. I like the whole site; it seems to be one person writing it.)
