Senecio gregorii
Also called Daisy Family, Aster Family, Composite Family, Thistle Family, Sunflowers, Sunflower Family, Sunflowers, Daisies, Asters, And Allies
Senecio gregorii, commonly known as annual yellowtop or fleshy groundsel, is a native Australian wildflower species, found in arid and semi-arid regions of the Australia and across the globe. It often grows prolifically after autumn/winter rains, showcasing stunning yellow flowers and fleshy foliage. The scientific name of this species was first published by Ferdinand von Mueller.
Native bees (family: Halictidae) are key pollinators of S. gregorii plants, allowing both species to persist in their habitats. Some foraging vertebrate and invertebrate animal species rely on S. gregorii as a food source. For example, caterpillars of the moth Heliothis punctifera consume S. gregorii flowerheads before completing their development. Hence, the distribution and abundance of certain animal species depends upon the ecological patterns of S. gregorii.
