Botanical name: Rudbeckia
Common name: Coneflower or black-eyed Susan
The starry flowers of these robust, long-flowering plants can shine in borders, summer bedding, containers and prairie-style plantings. Perennials tend to be yellow flowered, whereas those grown as annuals are available in a wider colour range, with shades of yellow, orange, dark red or brown. The foliage can be hairy or smooth and comes in green or grey.
