What is a defining characteristic of dandelions?

1. They have shallow roots

2. They have a sturdy taproot

3. They bloom in spring

4. They grow in clusters

The correct answer is: They have a sturdy taproot

Dandelions are well-known for their sturdy taproot, which is a significant characteristic of the plant. This taproot can penetrate deeply into the soil, allowing the dandelion to access nutrients and water that may be out of reach for other plants. Additionally, the presence of a strong taproot contributes to the resilience of dandelions, enabling them to survive in various environmental conditions and often making them challenging to eradicate from lawns and gardens. While dandelions may bloom in spring and can sometimes appear in clusters, these traits are not as defining or unique to their identity as the sturdy taproot. The taproot's structure is an essential part of their growth habit and significantly influences their spread and persistence in many landscapes.
