Perennial & Biennial Seeds


Biennials live for 2 years, whereas perennials live for longer. As a general rule, biennial and perennial seeds should be sown in spring, but some can be sown in autumn as well. Many varieties will self-seed after flowering, giving you even more plants!

Oenothera Versicolor Sunset Boulevard

Oenothera versicolor 'Sunset Boulevard'

Evening Primrose, Sundrops

  Customer Rating

Well branched plants, red stemmed with rich green, lanceolate foliage. The striking flowers are in whorls, vivid orange/red when fully open and when over, turn to red. Like many Oenotheras, the combination of open and spent bloom together, is stunning. This very choice plant makes a wonderful addition to the perennial border and because it flowers in its first year from sowing, it also makes an attractive annual.
