Definition: In the context of botany, a polderboy is a type of plant that grows in shallow soil and can be found on the banks or near water sources. The name "polderboy" likely refers to their ability to grow in such conditions, as they are adapted to living in sandy soils rather than rocky ones like pebbles or gravel. They may also have adapted to thrive in these conditions by developing specialized root systems and a thickened bark that can help them survive the elements.
