Figure 5. — A row of 7-year-old plants of Wood's 

 rose showing how plants have branched out by 

 sprouting. This presents a very effective ground 

 cover with the ability to hold soil on this rocky 

 road cut. Plants are about 4 feet (1.2 m) tall 

 and 4 feet (1.2 m) wide. 



Figure 6. — Six-year-old bush penstemon plants 

 have expanded to form dense mats 3 feet (0.9 m) 

 in diameter with attractive flowers. Soil on 

 the steep bank is effectively stabilized. 



Figure 7. — Lovely penstemon on a rocky road 

 cut has expanded and holds loose soil material. 

 Branching is more loosely arranged without form- 

 ing mats. Flowers are produced frequently and 

 resemble those on bush penstemon. Many new 

 seedlings are established from seed. This site 

 is out of the native range of this species. 



Figure 8. — A 9-year-old red-osier dogwood on 

 a steep south slope provides good ground cover 

 and stabilization. Crowns spread to 6 feet (1.8 m) 

 wide and 4 feet (1.2 m) tall and are quite 

 attractive.
