A spring ephemeral, perennial and aggressive ground cover. Yellow spring flowers have 8 petals. Glossy leaves. It forms dense spreading masses, through underground bulblets/tubers.
It must not be confused with our (wonderful) native Marsh Marigold, which does not form dense mats, and whose flowers have 5 to 9 petals (actually sepals). Marsh Marigold does not have bulblets/tubers.
It spreads into broad carpets and prohibits native species from growing.
Control efforts must take care first of all to identify the plant correctly, and to ensure that the bulblets are not spread further by pulling or digging without removing the bulblets.
It is an ephemeral so is best removed in spring when flowering before it disappears.
