A hedgerow plant is a type of vegetation that is planted along the edges of fields, roads, and other areas to form a barrier. YARROW (6 letters) is a common hedgerow plant that has feathery leaves and clusters of small white flowers. SHRUB (5 letters) is another type of hedgerow plant that is usually woody and can range in size from small to large. Both YARROW and SHRUB are popular hedgerow plants due to their ability to provide a natural barrier and aesthetic appeal.
