This useful hardy annual adds zingy spring freshness to borders and cut flower arrangements later on in the season. Euphorbia-like, citrus green flowers bloom on tall stems from July to September. The foliage is reminiscent of Eucalyptus, with intriguing stems that appear to grow through the leaf. Versatile and easy to grow, Bupleurum riotundifolium 'Green Gold' makes a superb filler for summer borders. Sow it alongside tall Ageratum, such as 'Timeless' for beautiful cut flowers, or interplanted with wildflowers for a stylish Cottage Garden look. If you like the look then let it set seed in late summer for drifts of fresh seedlings next year. Height: 80cm (31"). Spread: 40cm (16").
