Anchusa azurea is a very beautiful flower. But I haven't seen it till now. In Switzerland we have Anchusa arvensis (light blue) and Anchusa officinalis (dark blue).
It usually flowers in late spring, is not very common, usually in disturbed ground - in fields that are left fallow, etc. I believe this is also a cultivated flowering plant, probably with care the flower display is much more impressive, I once grew Verbascum sinuatum and it bore little comparison to the specimens found in the wild - much larger flowers and plant.
Similarly in Sicily wild plants seem to grow larger... Giant fennel grows commonly well over 2m tall. More water, deeper soils.
Probably too much water - probably needs growing in pure compost as it is difficult to maintain correct humidity levels in a pot when using any local soil. I tend to lose Cistus that way, this year have sown in a mix of compost and a decent percentage of Etna lava sand which makes the medium very very free draining. Same with Sage, very sensitive to water in Summer (hates it...)
I follow your debate with interest. It is difficult to grow wild plants. That's why I only have wild flowers in my garden, which have gone up by itself.
I'm going to show our Anchusa. They are not in my garden, I found them on the edge of a corn field.
