The selected hybrid, Bidens ‘Rockstar’ of the Asteraceae family has flowers twice the size of any previous Biden’s varieties on the market so makes a real splash of gold in your garden or in baskets and pots. The bright yellow flowers are borne in profusion all through the season. In warmer areas they flower right through the winter and continue flowering all through the year. They give a distinct splash of brilliant golden colour amongst other plantings of smaller shrubs and flower borders. They do best growing in full sun.
