2. Project Introduction • Re- design of bed located at Colorado State University’s Plant Environmental Research Center (PERC). • Incorporation of a variety of perennial trial plants desired.

3. Site Analysis • Located outside the Plant Environmental Research Center on W. Lake St. • Exposure: NW portion of bed will be mostly shaded. While the SE portion will be sunny. • Soil: Clay Loam 7.3 pH

4. Site Requirements • The Celtisoccidentalis(Hackberry)and Gelditsiatriacanthos(Honey Locust)must remain in the landscape. (Located in north-west region of bed.) • Pop up irrigation system already installed at site. • Use of plants that allow for year round landscape color and texture.

5. Objectives • Utilize perennials in a landscape that displays color and texture year round. • Theme: The Four Seasons • Removal of turf and existing plant material, removal of railroad ties for additional space, and application of mulch • Plant selections represent a diversity of plant size, color, texture, and bloom time.

14. Spring Plant Selections • Spring plant choices represent a variety of early blooming ground cover, as well as taller more showy species. • Most of the Spring plant choices are shade loving plants, which will be well suited for the shady area of the bed near the trees that remain. • Plants selected will offer an aesthetic display throughout the Spring season (March-May).

15. Summer Perennials Hosta Holly Hock Foxglove Shasta Daisy Sweet Woodrough

16. Summer Plant Chart

17. Summer Plant Selections • Used both shade and sun loving species to create a wide array of color during the summer months. • Incorporated species that offered either robust color or sweet fragrance to the display. • Use of varying heights to create a balanced contrast between plant sizes.

18. Overall Design = Fall = Winter = Spring = Summer

19. Conclusion • Provide the CSU PERC facilities with a re-designed and attractive entrance . • Create a perennial display that incorporates a variety of plants that provide a year -round aesthetic experience.
