Campfire Marshmallow Bidens

Campfire Marshmallow is a hybrid Bidens with white flowers centered in gold and a rounded, spreading form. Its pale blooms bring a softer color to sunny containers and mixed borders. ## Garden use and appearance Proven Winners gives the exact selection’s mature size as 8–14 inches tall and 16–20 inches wide, lists full sun, and describes flowering from spring to hard frost ([Campfire Marshmallow](https://www.provenwinners.com/plants/bidens/campfire-marshmallow-bidens-hybrid)). The breeder lists USDA zones 9a–11b, represented here as zones 9–11. Mississippi State University Extension also discusses Campfire Marshmallow, describing creamy white flowers with blush tones and use in containers and mixed plantings ([Mississippi State Extension](https://extension.msstate.edu/news/southern-gardening/2026/have-garden-campfire-colorful-biden-series)). ## Growing conditions Choose a site with full sun and soil that drains freely. Water regularly while plants establish; containers and baskets need closer moisture checks during warm weather. The mounded, spreading form can soften a container edge or fill the front of a seasonal bed. ## Seasonal interest The breeder lists flowering from spring through hard frost. White petals with golden centers brighten mixed plantings and pair readily with lavender, blue, purple, or stronger red-orange flowers. ## Maintenance The breeder describes the flowers as self-cleaning, so routine deadheading is unnecessary. Water container plants before they wilt and trim lightly if stems become leggy. In colder climates, grow this selection as a seasonal annual.
