Herbaceous plants

Herbaceous plants

Herbaceous plants enrich your Idaho landscape with four splendid seasons of color and excitement. Learn how to create your own unique landscape by choosing plants that fit your needs and desires and how to give the plants that you’ve chosen the optimum opportunity for outstanding performance.

Annuals

Annuals are plants that only live for one growing season. Annual flowers can add a lot of color and variety to a landscape, especially because they must be replanted or changed each year. Many gardeners in Idaho find it fun to start annual seeds indoors so that when the warm weather arrives, they can plant already blooming plants.
