Lysimachia nummularia "Aurea"
Perennial starter - 9cm pot. This eye-catching ground cover has bright lime-yellow leaves that are bright yellow in response to greater sunlight and has yellow flowers in spring/summer. It prefers moist soil, tolerating quite wet conditions. Can look great hanging over pots, banks or for providing colour under shrubs. I grow it amongst ajuga with its purple leaves for an awesome contrast. It is a ground cover so will spread along but is not invasive and easy to remove wandering tendrils that appear where they are not wanted.
