You know, part of the appeal of this plant is that it was named after John Parkinson, the 17th century botanist, by the British botanist Joseph Hooker. Hooker was director of Kew Gardens (where I trained) in the 19th century.
What I like about Parkinson is his sense of humor. His famous book on gardening from 1629, one of the very first, is called
Paradisi in Sole Paradisus Terrestris. That translates as 'The Earthly Paradise of Park-in-sun' ('paradisis' being both paradise and just a park). When I see his name used, it always makes me chuckle inside. That's the kind of weird person I am!
