Bidens ferulifolia

Bidens ferulifolia (Golden Empire) Grow it in a sunny, well-ventilated, well-drained area. If the plant grows taller and taller and becomes unsightly, cut it back as appropriate. The cold is relatively strong, so if it does not freeze, it can overwinter in the open air, but do not expose it to frost or cold winds. In temperate regions, it can overwinter in evergreen.
