Hazel Dodder (Cuscuta coryli)
Hazel dodder is a rare parasitic plant that attaches to various host plants, often members of the Asteraceae (aster) family.
Considerations for Pets
- As a vine, Hazel Dodder may present a risk of entanglement.
- Hazel Dodder is a parasite, thus it attaches to plants with a haustorium, which could potentially be concerning if ingested.
Taxonomy and Nomenclature
- Scientific Name: Cuscuta coryli Engelm.
- Common Name: Hazel Dodder
- Kingdom: Plantae
- Division: Tracheophyta, Magnoliophyta
- Class: Magnoliopsida

- Synonym: Grammica coryli
Distribution and Habitat
- Hazel dodder is native to the U.S.
- Specimens have been recorded in the ISM Herbarium.
Ecological Role
- Hazel dodder is a holoparasite, meaning it derives its nutrients entirely from its host plant.
- It can weaken host plants if it spreads aggressively.
Morphological Characteristics and Growth Habits
- Hazel dodder is a leafless annual vine of indeterminate length.
- It lacks chlorophyll and is therefore dependent on its host for survival.
- It attaches to other plants using a structure called a haustorium.
Interactions with Other Organisms
- It parasitizes a variety of host plants, including hazelnut, wild licorice, and members of the Asteraceae family.
- It has been observed attaching to Jewelweed.
