Dandelions are common as muck. Right? Well not really. There are 250ish species of dandelion in the UK, and this one is probably the rarest plant I've seen. It's the St Kildan Dandelion (Taraxicum pankhurstium) It's found only on St Kilda. It's also the easiest to identify, because it's the only species of dandelion on St Kilda. It's closely related to Icelandic species.
