The sepals do not have appendages on them The sepals are green or brown, and leaf-like in texture The petal outline is obovate (roughly egg-shaped, but with the widest point above the middle of the leaf blade)Īll the flowers have both carpels and stamens (synoecious) The petals of the flower do not have folds or plaits The petals are thin and delicate, and pigmented (colored other than green or brown) The flower includes two cycles of petal- or sepal-like structures The ovary is above the point of petal and/or sepal attachment There are five petals, sepals, or tepals in the flower There are no noticeable marks on the petals The flowers are arrayed in a spiral around the inflorescence axis or branches, or occur singly, or in several ranks The axis of the inflorescence has hairs entirely without glands There are two or more ways to evenly divide the flower (the flower is radially symmetrical)īoth the petals and sepals are separate and not fused The flower has both pollen- and seed-producing parts The flower has a superior ovary, and lacks a hypanthium The filament is smooth, with no hairs or scales There are no cleistogamous flowers on the plan The carpel is solitary or (if 2 or more) the carpels are not fused to one another There are two or more ways to evenly divide the calyx (the calyx is radially symmetrical) The anthers have narrow slits or furrows that run lengthwise along the anthers For additional information about application rates and use follow the label directions.The anthers show no hint of a pink, reddish or purplish tint However, use caution with these products near ornamentals as the potential for volatilization (movement of pesticide vapors through the air) does exist in warmer temperatures. These products should not be used near delicate, valuable plants or vegetable gardens. They are labeled to manage many broadleaf weeds found in lawns. Products containing at least two of the following active ingredients (look on the product label) have been found effective MCPA, triclopyr, or dicamba. In this area, it is recommended to wait until half the plants are in bloom to start control. Waiting beyond this period of time may cause damage to many native wildflowers that share some sites. Begin in mid-February to early April as long as the temperature is 50 degrees Fahrenheit and no rain is anticipated within 12 hours.

Aqua-neat or Aqua-star are glyphosate formulated products labeled for wetland areas. Digging out plants can be successful with small patches, but it will take careful removal of all the bulblets and removal of all plant material to either a landfill or other means of destruction.Ĭhemical control can be achieved using a glyphosate (a non-selective herbicide) product early in the season.

These plants are 3- to 9-in high and have shiny, dark green, kidney-shaped leaves flowers with glossy, bright yellow petals in early spring the entire plant goes dormant in the summer. This plant may be misidentified as marsh marigold, Caltha palustris, which does not produce the tuber found on lesser celandine. Lesser celandine, also called fig buttercup, is an herbaceous invasive perennial plant found most often in moist, wooded floodplains. This spring ephemeral arises early in the season, often near forest fringe areas, and creates a dense carpet of vegetation that prevents native ephemeral plants such as bloodroot, wild ginger, and others from surviving.
