Oenothera fruticosa 'FYRVERKERI'

Evening primrose is a large genus of many annuals, biennials, and most importantly perennials from sunny and hot landscapes of North America, S.W. USA, and Mexico. A lot of perennial species are hardy enough for C.E. climate, too, they just resent water-logged soils. In our country mostly yellow flowering species are cultivated, especially appreciated for their evening performance of fast flower opening which happens just before your eyes and takes some 5-10 minutes. Still, there are some which flower during the day owing to which the name evening primrose was changed to sundrops.

Fyrverkeri (Fireworks) is very probably a Swedish variety of daytime sundrops with large, rich yellow flowers from late June for 4-8 weeks. They are saucer-shaped and appear atop and along 40-60 cm tall stems which makes it a compact and shorter variety compared to the species. Deciduous leaves are shortly lance-shaped, medium green.

Sundrops likes common garden soil, not too dry, not too wet, but preferably moist and fertile – in poor soil its flowering is quickly over. Fully sun only. Hardy to about -34°C (USDA zone 4).
