French peony Persian buttercup was added to one of our landscapes last year. They are not two different perennials, such as French peony and Persian buttercup. They are a group of cultivars of one species, Ranunculus asiaticus ‘French Peony’. Ranunculus asiaticus is the species of Persian buttercup. ‘French Peony’ is its cultivar.

So, is it French or Persian? Well, yes.

Ranunculus asiaticus, Persian buttercup is native to Southwestern Asia, Southeastern Europe, Northeastern Africa and elsewhere within the Mediterranean Region. This range could potentially include the Southern Coast of France within the Mediterranean Region, but much more likely includes Persia within Southwestern Asia. My guess would be that Persian buttercup is as Persian as its name says it is.

‘French Peony’ is a group of cultivars that could have been developed anywhere and given an appealing name that promotes its marketability, but was most likely developed in France, where most breeding of this particular species was done. My guess would be that ‘French Peony’ is as French as its name says it is.

Of course, French peony Persian buttercup could have been developed anywhere, even Persia, and merely given its appealing French name without actually being French. Alternatively, it could have been developed completely in France, from Ranunculus asiaticus from the Southern Coast of France, without actually being Persian. For that matter, it could have been developed in Greece from Greek stock.

To me, French peony Persian buttercup seems to be chicly cosmopolitan. I remember it as popular for urban window boxes within the greatest cities of the World, such as San Jose, Oakland and San Francisco. If I had not seen that it is also popular in Reno and Portland, I would consider it to be as Californian as so many other exotic species and varieties that are popular here.
