The Most Beautiful Ornamental Trees to Grow in Idaho
Any garden is incomplete without ornamental trees. These are grown for their visual appeal rather than their ability to produce fruits or vegetables. As a result, they require less pruning and fertilizer than other types of plants. They can act as windbreaks, provide shade and protect against erosion. In addition, ornamental plants help to attract bees and other pollinators, which are essential for the health of your garden. When choosing ornamental plants for your garden, selecting species that are well-suited to your climate and soil type is important. With proper research, you can identify plants well-suited for your locality. Here are ornamental trees that will thrive in Idaho.
