Plant Category

Aquatic, Perennial

Invasive Description

Native to east Asia and the Mediterranean, Yellow Floating Heart was introduced as a water garden plant in 1882 and escaped cultivation. It is a freshwater floating perennial that grows in lakes, ponds, swamps and channels with slow-moving water. Its runners aggressively root in the substrate. Most leaves are floating, some remain submersed. Floating leaves range from 1 – 6 inches in diameter. Flowers, ranging from 1 – 1.5 inches in diameter, are yellow with five petals, each of which has fringed edges. Flowers are held above the water’s surface on a stalk that can support 2-5 flowers.

Ecological Threat

Yellow Floating Heart grows rapidly, covering entire surface of the water and shading out and outcompeting natives. Decomposing vegetation causes stagnant, low-oxygen conditions in the water below, impacting water quality and other aquatic species. These areas of stagnant water can be an ideal location for mosquitos to breed. The shading from the mats can cause severe declines in algae, disrupting the entire food web. The mat-like patches impede recreational activities such as fishing, water skiing, swimming and boating.
