It grows up to 3 feet tall and wide, and produces yellow flowers in the summer and fall. Propagation of this plant can be achieved through various methods:
Seed Propagation
The easiest and most common way to propagate the wedgeleaf goldenbush is through seed propagation. Collect ripe seeds in the fall when the flower heads have turned brown and dry. Clean the seeds and store them in a cool and dry place until ready to plant. Sow the seeds in a seedling tray filled with well-draining soil, and cover with a thin layer of soil.

Plant the cutting in a pot filled with well-draining soil, and keep it in a warm and bright location. Keep the soil moist and the cutting should form roots within a few weeks.
Division Propagation
Propagation through division is suitable for mature plants that have grown too large or become overcrowded. Carefully dig up the plant and separate the roots into smaller sections.
