Notes: Sneezeweed has yellow flowers with a yellow ball in the centre surrounded by frilly petals. A spray of these flowers is quite attractive and it is often planted in gardens both ornamental and wild. The plant itself is native to a large area of North America and typically grows in wet meadows or marshes.
It starts blooming in August and goes well into September. Its interesting flowers and its long bloom has encouraged plant breeders to produce various cultivars by cross-breeding with other species*. These cultivars should be avoided in a wildlife garden.
This plant is notable for growing well in clay soil. It likes a sunny place to grow and it will tolerate part-sun if it is given some support.
