3102 Yellow Marsh Marigold ( Caltha palustris )
A wonderful, bright yellow plant for moist or even boggy areas, very hardy, grows about 12" tall, hardy to zone 3.Perennial.
The name would seem to imply that marsh marigolds grow in marshy areas. Most descriptions of it do imply that they will only grow in consistently wet and shady areas, however this is not true, it will grow just about anywhere.
