This Marsh marigold heralds the spring with a gorgeous display of multi-petalled vibrant yellow flowers. Green leaves are round and serrated. Should be left to grow into pleasing clumps which, when large enough for their situation, can be raised very early in the year as growth starts for splitting; tease the roots apart to divide into smaller clumps and plant in a medium container using aquatic soil and covering with pea gravel. Do not bury the crown of the plant. After flowering, remove the dead flower heads and this lovely plant will often flower again in late summer/early autumn.
