Eranthis hyemalis ‘Flore Pleno’

Yes indeed, a double-flowered eranthis, which produces pompons of yellow and chartreuse in late winter. The occasional bloom reverts to single, thus raising the possibility of raising seedlings that may themselves be doubles. This rare and much sought-after cultivar is one of the parents of a mini-swarm of acolyte aconites that are about to hit the market. Modified continental/Mediterranean. Zone 5.
