  • Ranunculus Ficaria (Ranunculaceae) Naturalized in Texas: Update
    Nesom, G.L. 2015. Ranunculus ficaria (Ranunculaceae) naturalized in Texas: Update. Phytoneuron 2015-27: 1–7. Published 29 April 2015. ISSN 2153 733X RANUNCULUS FICARIA (RANUNCULACEAE) NATURALIZED IN TEXAS: UPDATE GUY L. NESOM 2925 Hartwood Drive Fort Worth, Texas 76109 [email protected] ABSTRACT In the 7 years since a report of its naturalization along a creek in Tarrant County, Texas, Ranunculus ficaria (now treated within the genus Ficaria as F. verna ) has increased in number of plants and coverage at that locality. The Texas plants produce axillary bulbils and flowers apparently are sterile, producing only unexpanded achenes. Photos show population structure and characteristics of the habitat. Ranunculus ficaria L. was earlier observed (Nesom 2008) to be naturalized along Overton Creek within Overton Park in Fort Worth, Texas. It was noted that "Thirty discrete plants, clearly naturalized, grow in an area of about 30 square feet ... A second population of five scattered plants occurs on the stream terrace about 300 yards downstream." In 2015, areal coverage of plants of Ranunculus ficaria has increased by about 6 times; the original larger population has expanded, additional colonies have formed downstream between 20 and 50 yards from the original, and an additional large population has arisen downstream of plants seen in 2008, increasing the linear extent of the total population to about 400 yards. Photos of subgroups of the Overton Park population (Figs. 1–7) show the characteristic habitat and dispersion of the plants –– all are growing in wet soil immediately beside the water or close by on the low, frequently flooded terrace.

  • Ficaria Verna Huds
    DRAFT: WRITTEN FINDINGS OF THE WASHINGTON STATE NOXIOUS WEED CONTROL BOARD DRAFT July 2013 Scientific name: Ficaria verna Huds. Synonyms: Ranunculus ficaria L., Ranunculus ficaria L. ssp. bulbifera (Marsden-Jones) Lawalree, Ranunculus ficaria L. ssp. calthifolius (Reichenbach) Arcangeli, Ranunculus ficaria L. var. bulbifera Marsden-Jones, Ficaria verna Huds. Common name: Lesser celandine, fig buttercup, pilewort, figroot buttercup, figwort, bulbous buttercup, and small crowfoot Family: Ranunculaceae Legal Status: Proposed Class B noxious weed Images from left to right: 1. Plant growth with flowers, image: Catherine Herms, The Ohio State University, Bugwood.org; 2.Tuberous roots of Ficaria verna, image: Leslie J. Mehrhoff, University of Connecticut, Bugwood.org; 3. Close up of flower, image: Leslie J. Mehrhoff, University of Connecticut, Bugwood.org; 4. Bulbils in leaf axils, image: Leslie J. Mehrhoff, University of Connecticut, Bugwood.org. Description and Variation: As Post et al. (2009) outline, North American treatments of Ficaria verna did not include subspecies or only included one while European treatments include five subspecies: subsp. ficariiformis, subsp. chrysocephalus, subsp. calthifolius, subsp. ficaria, subsp. bulbilifer. Through a review of herbarium specimens, Post et al. (2009) determined that all five subspecies existed here in the United States. Sell (1994) provides descriptions of all five subspecies. Whittemore (1997) states that the species is highly variable and that the different forms intergrade extensively and varieties are often impossible to distinguish. Listing Ficaria verna as a Class C noxious weed includes all subspecies of F. verna and any cultivars of the species and subspecies. Overall Habit: Ficaria verna is a highly variable, glabrous perennial with tuberous roots.

Everyone was determined to make the most of sunshine on the first day of what for many, was their first real trip out in almost 18 months. We headed straight out on the Lizard peninsula past Culdrose Naval station and through the pretty village of Gunwalloe, down to Church Cove. Every hedge was hazed navy blue with Bluebells and clouds of Cow Parsley brushed the van on the narrow lanes. In glorious late afternoon sunshine, we wandered out of the car park towards the cove. The Cornish hedges were covered in the glossy green leaves of Sea Beet (Beta maritima) interspersed with Danish Scurvygrass (Cochlearia danica) that was coming to the end of its flowering season. As we got nearer to the beach, one wall was covered from top to bottom with a blanket of Sea Sandwort (Honckenya peploides) in full flower. The cliffs were dotted with Common Scurvygrass (Cochlearia officinalis) and huge mounds of Thrift (Armeria maritima). Up on top of the cliffs we came across our first blue Spring Squills (Scilla verna).

Family name: Renunculaceae - buttercup family. Pictures (left to right): Lesser celandine plant in bloom (left) and tubers/bulbils (right). Picture courtesy: Les Mehrhoff, University of Connecticut (left), and David L. Clement, University of Maryland (right), Bugwood.org. US introduction and distribution: Lesser celandine also known as fig buttercup is a perennial herb native to Europe, temperate Asia, and northern Africa. It was introduced into North America from Europe for ornamental use. The earliest record of its presence in the Unites States dates to 1867 from Philadelphia County, Pennsylvania. Historically, lesser celandine has been used as a medicinal plant for treatment of hemorrhoids and scurvy due to high vitamin C content of the young leaves. Five subspecies are known to exist in the United States (Post et al 2009). Of these, Ficaria verna or Ranunculus ficaria subsp. calthifolius has the widest distribution and R. ficaria subsp. chrysocephalus has the most limited distribution. Currently, lesser celandine is 1 present throughout the northeastern United States and west to Missouri, and in the Pacific Northwest. (EDDMaps 2020). Lesser Celandine US distribution (Map: EDDMapS.

Agency Contact: Plant Epidemiology and Risk Analysis Laboratory Center for Plant Health Science and Technology Plant Protection and Quarantine Animal and Plant Health Inspection Service United States Department of Agriculture 1730 Varsity Drive, Suite 300 Raleigh, NC 27606 Weed Risk Assessment for Ficaria verna Huds Introduction Plant Protection and Quarantine (PPQ) regulates noxious weeds under the authority of the Plant Protection Act (7 U.S.C. § 7701-7786, 2000) and the Federal Seed Act (7 U.S.C. § 1581-1610, 1939). A noxious weed is defined as “any plant or plant product that can directly or indirectly injure or cause damage to crops (including nursery stock or plant products), livestock, poultry, or other interests of agriculture, irrigation, navigation, the natural resources of the United States, the public health, or the environment” (7 U.S.C. § 7701-7786, 2000). We use the PPQ weed risk assessment (WRA) process (PPQ, 2015) to evaluate the risk potential of plants, including those newly detected in the United States, those proposed for import, and those emerging as weeds elsewhere in the world. The PPQ WRA process includes three analytical components that together describe the risk profile of a plant species (risk potential, uncertainty, and geographic potential; PPQ, 2015).

  • Ficaria Verna – Lesser Celandine
    Ficaria verna – Lesser celandine Commonly referred to as fig buttercup, lesser What is it? celandine is an herbaceous perennial from the buttercup family (Ranunculaceae). It has glossy yellow flowers with 7 or more long, narrow petals and thick, deep green (sometimes silver splotched), kidney-shaped or lobed leaves. Photo by R. Buczynski 2020 Lesser celandine is ephemeral (a type of plant that appears in early spring when there is more available sunlight that dies back once trees are in full leaf). In early summer it will appear to disappear before your very eyes. That does not mean the plant is gone by any means. Look carefully and you will see evidence of the tubers and loose bulblets (reproductive structures that form in the leaf notches on the stem) on the bare soil; a promise that it will come back full Photo by A. A. Reznicek force next year. 4.9.2020 Where is it from? This species was brought to the Western hemisphere from Europe as a garden plant. Although considered a noxious weed in many states it is still commercially available. Where is it now? Lesser celandine is highly adaptive and although it grows most prolifically in floodplains it can grow in higher and drier conditions as well. It is present in all 3 counties in the Upper Raritan Watershed – Hunterdon, Morris, and Somerset – and is especially pervasive in Somerset county along riparian corridors. Photo by R. Buczynski 2020 When does it grow? Lesser celandine is most easily spotted in early spring when it is in bloom. In our region this is usually the last week in March through the end of May.
