Ranunculus repens 'Buttered Popcorn'

Ranunculus repens 'Buttered Popcorn' (Ranunculaceae)

 The gold leaved form of this water loving buttercup is a real winner but it can be a bit invasive if given a damp spot in shade. I am keeping mine in a pot half submerged in water so it can be moved from sun in spring to deep shade at the height of summer. Technically you could describe it as a woodland margin plant fond of damp ditches in Northern Hemisphere locations and this selected form is useful for brightening dull  garden corners, though its leaves may become less yellow in deep shade.
There are some 400 species of buttercup found in temperate zones across the world including Australia. Most have shiny yellow ,cream or white flowers.
