Whilst weird things like the Aeoniums and Echiums can be found found growing wild in West Cornwall, in the Scillies they are so commonplace the they begin to seem normal. On getting back to mainland England I found the hedgerows looked decidedly odd.
Oddest of all where the Hottentot Figs. Originally from Chile they are now regarded in Europe as an invasive weed. I first encountered them in Gibraltar, and finding them growing in abundance on the Isles of Scilly just enhanced the feeling of being in a foreign country.
That said, since getting back from the Scillies, I noticed some on the cliffs down in Bournemouth the other day. Not so exotic after all.
