I had to look very hard to find a picture of Shrubby Sea-blite that even remotely resembled the shots I took, perhaps most people concentrate on younger growth. On the Sea Aster, that was my first port of call but I can't find any references showing yellow flowers. The Viper's Bugloss flower was a clue I didn't pick up. If I'd have got a closer look at the base it may have been easier but, again, the plant was well past it and references all show a much less emaciated plant. I'll have to try again earlier in the year.
