A dazzling display of semi-double, golden flowers appear above the spreading feathery foliage of this showy Bidens. These undemanding plants are ideal for spilling over the edges of patio pots and hanging baskets. Like other modern varieties these plants are more compact, and less likely to become straggly over time. They make fabulous filler for mixed containers, but are equally good when planted as a single variety. Try filling beds and raised beds with Bidens \'Yellow Port Royal\' for an informal groundcover display in summer. Height: 30cm (12?). Spread: 35cm (14?).
