This course offers landscape designers a practical introduction to ornamental horticulture, focusing on the identification, selection, and use of common landscape plants.
Participants will explore a wide range of trees, shrubs, groundcovers, and perennials suited for various design applications and environmental conditions. Emphasis is placed on plant characteristics, aesthetic value, seasonal interest, and sustainable landscape practices. By the end of the course, designers will be equipped with the knowledge they need to confidently incorporate plant materials into functional and visually compelling landscapes.
