Sundrops, or Narrow-leaved Evening Primrose, features large yellow flowers that open in spring on red buds and stems tinged with red.
 
     Each bloom lasts just a day, but a profusion of blooms follows as each one fades, creating a carpet of yellow in a sunny garden.
 
     Sundrops feeds all sorts of pollinators including butterflies, moths, beetles and native bees. This plant makes a great ground cover and is happiest when given room to spread out.
