Fun Facts
- 🌱 The genus name 'Bidens' refers to the distinctive two-pronged seed heads that readily cling to clothing and animal fur, facilitating seed dispersal—this is why some species are called 'beggar-ticks'
- 🌱 Fire Island is a hybrid cultivar, likely bred from Bidens ferulifolia, and offers improved ornamental qualities including more vibrant color and fuller blooming compared to species forms
- 🌱 Unlike many annuals, Bidens becomes more floriferous and full as the season progresses, often producing its heaviest bloom display in mid to late summer
