The [RHS species profile](https://www.rhs.org.uk/plants/27935/bidens-ferulifolia/details) provides general species guidance for full sun and well-drained soil. Use it in sunny containers, hanging baskets, or border edges where the wider spread has room. A part-shade site can work in hot conditions, while flowering may be strongest with ample light. ## Growing conditions Plant in fertile, freely draining soil and water consistently during active growth. Keep containers from drying out for long periods, but do not leave the roots saturated. The plant is commonly grown as an annual where winter temperatures fall below its listed hardiness range. ## Maintenance Remove damaged stems as needed and inspect for aphids and other soft-bodied pests. Trim lightly if growth extends beyond its allotted space.
