life cycle habit
- URI: http://purl.obolibrary.org/obo/TO_0002725
- Definition: Determined for type of life cycle being annual, biennial, perennial etc.
- Comment: The life cycle habit indicates the typical duration of an individual plant's life. Common values are annual, biennial, and perennial. Some plants have different durations depending on environment or location, so a plant can have more than one value.
