The typical forms of Ranunculus ficaria are such indomitable weeds in this area that I never thought I would invite one into the garden (which is already overrun with one of the common forms). But something I'm seeing in a few local gardens may be weakening my resolve. I've posted to the wiki an image which shows a very robust, large-flowered form. The image shows a flower of this large-flowered form next to that of a typical form. Take a look at: http://pacificbulbsociety.org/pbswiki/index.php/… The lesser celandines are sometimes placed in a genus of their own, Ficaria. An IPNI search brings up 38 names. Does anyone know if this large-flowered form has a name? Jim McKenney Montgomery County, Maryland, USA, USDA zone 7, where we get a "desert in bloom" effect when the lesser celandine blooms here.
