Senecio, a diverse genus of the daisy family Asteraceae, includes plants that range from annuals and perennials to shrubs and succulents. With over 1,000 species scattered across various habitats around the world, senecios vary greatly in appearance, but most share some common floral characteristics such as composite flower heads and a protective layer of bracts.
The scent profile of Senecio plants is generally not as prominent or celebrated as in other flowering plants. Many Senecio species have a subtle aroma, which can be described as earthy, with some having a slightly herbal undertone. The scent is typically more noticeable when the leaves are bruised or crushed, releasing their volatile oils. However, the aroma is usually not a primary attribute for which these plants are valued or described, as it does not tend to be particularly strong or distinctive in most species. Overall, Senecio's scent can be described as modest and understated, blending with its natural surroundings rather than standing out.
