Description of the plant:
Marsh marigold is our native perennial, naturally occurring from Central to North Europe as well as in North America and North Asia. It loves boggy and constantly moist locations in full sun. It is very variable and during a spring walk you can find several plants of slightly different appearance, yet belonging to the same taxon. Its rich golden yellow flowers can cheer up even the saddest person because they usually bloom when there are not many flowers and colours around yet – from late March until late May. Leaves are dark green, glossy, heart- or kidney-shaped, and their size is causally related to the level of nutrients and water in the ground and can measure up to 20 cm across. The plant is slightly poisonous, so wild animals don’t eat it.
Marsh marigold spreads by short suckers and under ideal conditions quickly forms substantial, dense colonies. Grow it in moist or boggy conditions in full sun. It needs humus-rich soil and will grow in a normal bed, too, provided it is kept moist. Otherwise it quickly loses leaves and withers. Hardy to about -30°C.
