What's that green thing

Don't recall ever seeing this colour ever.
A surprise plant pointed out today at Logan Botanical gardens by the curator Richard Baines on his guided tour.
Coffees in the bistro then down to the seaside home of friends M & D.
Beautiful blue skies and over 12 hours of sunshine with +20deg C. Today.
As chef for tonight I consrtucted a mushroom risotto for supper.
