I think Acanthus montanus. I had seen it growing in California

Muthu ji
A. mollis does not have spiny bracts. Your photograph shows clear spiny margined bracts and leaf segments

Muthu ji
The plant at FOI is perhaps wrongly identified as A. spinosus

A. mollis has leaves less deeply divided without spinose teeth, bracts and calyx teeth are are not spinose, calyx lobes hairy along margin

In both A. montanus and  A. spinosus (syn: A. spinosissimus) the leaf lobes and bracts are spinose.

In A. montanus leaves are glossy green above, less deeply pinnatifid; In A. spinosus the leaves are rigid, leathery, deeply pinnatifid with rigid spinose teeth.



Obviously both your plant as one on FOI is A. montanus



Needless to say that there is terrible mix up of photographs on the internet.
