Spatterdock
Nuphar advenaAlso known as Yellow Pond-lily, Broad-leaved Yellow Pond-lily, Cow Lily
Spatterdock anchors itself in soft sediment using thick rhizomes, thrusting heart-shaped leaves to the water surface or holding them erect above it. Its yellow, globe-like flowers barely open, relying on flies and beetles attracted to their faint alcoholic odor for pollination. Wetland birds and aquatic mammals frequently consume the seeds and starch-rich underground stems.

Responsible observation
- Viewing from Water: Approach quietly in a kayak or canoe to examine flowers without disturbing soft sediment.
- Stem Identification: Look for heart-shaped leaf blades held erect above the water on spongy, flattened stalks.
- Observing Pollinators: Watch the partially closed flowers in early summer to spot visiting beetles and flies.
