Environmental Horticulture

The Environmental Horticulture program at Lake Washington Institute of Technology provides high quality instruction and learning experiences for students who want to pursue a career in horticulture. Graduates will have skills needed to find employment in landscaping firms, garden centers, nurseries, public and private gardens, greenhouses and with landscape designers. This program operates under the cohort style of education where students follow the same classmates and instructors all the way through graduation. The educational style is oriented towards a technical education and classes include a significant hands-on component. This includes field trips, guest speakers, and practical experiences. Unparalleled program experiences include student-run plant sales where students grow and care for a crop from seed to sale, study arboretum, green industry work experiences and being an integral part of the annual Northwest Flower and Garden Show.
