Bidens tripartita seed
LATIN NAME: Bidens tripartita
COMMON NAME: Bur Marigold
The bur marigold carries its small, golden heads over the wet ground, and the long, barbed seeds catch at the passing coats. The upright, branching, annual or short-lived perennial plant carries the deeply divided, lance-shaped, green leaves and the small, golden-yellow, daisy-like flower heads in the loose clusters through the late summer, one of the bright, busy sights of the wet verge, to be followed by the curious, barbed, two-pronged seeds. The plant is a fine, generous presence of the damp ground, and it is a plant of the open, sunny to lightly shaded, moist ground.
Scientific Research & Plant Biotechnology
The bur marigold is a curious subject of the plant science, and the barbed seeds keep showing up in the work on the hitchhiking plants. The way the long, barbed, two-pronged seeds catch at the passing coats and the fur has been examined closely, and it keeps appearing in the studies of the seed-dispersal plants, the wetland herbs and the members of the daisy family. The deeply divided leaves and the branching habit have also made it a fine study plant, and the bur marigold is a regular subject of the work on the golden heads of the wet world.
Ecological & Economic Value & Wide Applications
The bur marigold is a fine, bright plant of the wet verge and the wild patch. The small, golden-yellow, daisy-like flower heads open through the late summer, drawing the bees and the small flies, and the curious, barbed, two-pronged seeds follow, one of the fine, curious sights of the plant world, carried on the passing coats and the fur. The plant is one of the fine choices for the wet verge, the wild patch and the study collection, and it has been written about in the botanical papers for the barbed seeds and the busy ways. It is a fine, bright plant of the open, sunny to lightly shaded, moist garden.
Keep the young plants in the moist, open spot, and the golden heads will come in the first season.
To grow the bur marigold from seed, press the small, brown seeds into the surface of the moist seed tray, without covering them, keep the tray in a bright, open spot and water gently, then set the young plants out in the open ground. The seedlings appear within a couple of weeks and grow on fast. With the sun or the light shade and the moist ground, the golden heads will open through the late summer.
