rosette
- URI: http://eol.org/schema/terms/rosette
- Definition: a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height

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.
