Now that conjures up some weird and wonderful images, doesn't it ?
It's actually the common name of this plant:
This is Acanthus mollis. It's displaying a glorious mound of foliage at the moment, quite unusual for late December. Acanthus mollis was originally introduced to Britain by the Romans, but was then lost to cultivation and reintroduced in 1548. I was introduced to it many years ago whilst watching Geoff Hamilton on TV. The programme was about his move to Barnsdale, and how he intended to remove all the existing plants in his new garden, to start afresh. But there was one plant that he intended to keep. Yes, you've guessed it, it was an acanthus.
I grew several plants from seed, and dotted them about the garden, all in shady areas. They took years to grow, but one by one, most of them produced flowers, although not every year. I have since discovered that they flower best in full sun. Oh well, back to the drawing board.
