Delaware Wildflowers  •  Scientific names

Ficaria verna Hudson ( Ranunculus ficaria ) Lesser Celandine
Ranunculaceae — Buttercup family
Invasive non-native
Ficaria verna
When I first saw this plant, in 1998, it was relatively uncommon. I had trouble finding a name for it; it wasn't listed in my field guides. Prices Corner
April 2001 Ficaria verna
Now it is among the worst of the invasive plants in Delaware. White Clay Creek State Park -- Pump House Road
April 2012 Ficaria verna
This plant covers acres along streams in Delaware, including the Brandywine Creek floodplain. Note the Virginia bluebells in the foreground. It's ideal habitat for both plants, but the bluebells can't compete. Brandywine Creek State Park
April 2004 Ficaria verna
The leaves emerge in late winter and form a dense mat.
Ficaria verna
The plant resembles the rare native marsh marigold , but three sepals confirm that it's celandine.
Ficaria verna
A single plant.
Ficaria verna
The plant spreads by growing new plants from tubers... Middle Run Valley Natural Area
March 2016 Ficaria verna
...and from bulblets that grow in the leaf axils.
Ficaria verna
The leaves die in late spring, leaving the bulblets free to be washed downstream or spread in mud on shoes and bike tires. White Clay Creek State Park -- Creek Road
May 2016

76. Ranunculus ficaria Linnaeus, Sp. Pl. 1: 550. 1753.

Lesser celandine, pilewort, ficaire, renoncule ficaire

Ranunculus ficaria subsp. bulbifer Lambinon; R . ficaria subsp. calthifolius (Reichenbach) Arcangeli; R . ficaria var. bulbifera Albert

Stems erect to decumbent, not rooting nodally, glabrous, not bulbous-based, spheric or ellipsoid bulbils sometimes formed in leaf axils. Tuberous roots present. Basal leaves simple and undivided, blades cordate to deltate or semicircular, 1.8-3.7 × 2-4 cm, base cordate, margins entire or crenate, apex rounded or obtuse. Flowers: receptacle glabrous; sepals spreading, saccate at extreme base, 4-9 × 3-6 mm, glabrous; petals yellow, 10-15 × 3-7 mm. Heads of achenes hemispheric, 4-5 × 6-8 mm; achenes 2.6-2.8 × 1.8-2 mm, pubescent; beak absent.

Flowering spring (Apr-May). Shaded stream banks and moist disturbed areas; 0-300 m; introduced; B.C., Nfld., Ont., Que.; Conn., D.C., Ill., Ky., Md., Mass., Mich., Mo., N.J., N.Y., Ohio, Oreg., Pa., R.I., Tenn., Va., Wash., W.Va.; native to Europe.

In North America, Ranunculus ficaria seems to be expanding its range rapidly in areas with cool mesic climates.

The species is extremely variable (especially in leaf size and stem posture), and many attempts have been made to divide it into varieties or subspecies (see P. D. Sell 1994). The different forms, however, intergrade extensively and the varieties are often impossible to distinguish.
