Quick Answer
To identify dandelion among similar plants, look for its distinctive jagged-toothed leaves, bright yellow flowers, and a hollow stem with a milky sap. Dandelion leaves typically grow from a single taproot, while other plants have multiple roots. Check for these characteristics to confirm the plant's identity.
Identifying Dandelion Leaves
Dandelion leaves are the key to identifying this plant. They have a distinctive jagged-toothed edge, with teeth that are pointed and irregular. The leaves typically have 3-5 lobes, with a wavy or toothed margin. Count the number of lobes to confirm the leaves belong to a dandelion. Note the color, which is usually a deep green, but may turn yellow or brown when the plant is stressed or dying. Measure the length of the leaves, which can range from 4 to 12 inches (10 to 30 cm) in length.
Examining the Stem and Flowers
The dandelion stem is hollow and has a milky sap that flows when the stem is cut. This characteristic is unique to dandelion and other members of the sunflower family. Look for bright yellow flowers with 100 to 400 individual florets, which are arranged in a spiral pattern. Count the number of flowers to confirm the plant is a dandelion. Note the shape and size of the flowers, which are typically 1 to 2 inches (2.5 to 5 cm) in diameter.
Confirming the Plant’s Identity
To confirm that the plant is a dandelion, check for the presence of a taproot. Dandelions have a single taproot that grows deep into the soil, while other plants have multiple roots. Dig around the plant to expose the roots, and look for the distinctive taproot. If the plant has multiple roots or no taproot, it may not be a dandelion.
