Seeds sense the sun return. Germination rapid with most species. Here's a photo of one of the more spectacular ones--Bidens pilosa--and a bit more info about the plant
Bidens pilosa
Family: Aster (Asteraceae)
Annual, requiring 100 days to complete fruition
(Xian-feng-cao, Blackjack, Cobbler's Pegs, Hairy Beggarsticks, Sticky Beaks, Farmer's Friend) Annual w**d, self-fertile, flowering rayless yellow disc, to a height of 5 feet, native to South America and introduced into warmer regions worldwide. Note should be made that contact with the fresh plant can cause photosensitivity. Wash with soap and water immediately after contact. However the plant is a good edible herb, being used as a potherb especially in Africa, and is also used in herbal medicine and veterinary medicine. Traditional uses of roots, leaves and seeds: For treating stomach woes in humans and for treating animal colic; antidysenteric; pain-relieving anodyne; antimicrobial; antimalarial; Lyme; hepatoprotective; hypotensive. Fast-growing plant prefers a sunny position in disturbed soil and may be propagated much as one would grow Mustard or Kale, in the field or garden bed. Germination of the needle-like achenes (seeds) is rapid. Surface-sow and press in hard, keep warm, moist and in the light. Space plants 2 to 3 feet apart.
