figureThe plastic behaviour of polymers is also influenced by their morphology, or arrangement of molecules on a large scale. Stated simply, polymer morphologies are either amorphous or crystalline. Amorphous molecules are arranged randomly and are intertwined, whereas crystalline molecules are arranged closely and in a discernible order.
Mountain Plant Life. Southern California has a Mediterranean climate. This means that the weather is warm and dry in the summer, and cool and wet in the winter. The San Bernardino Mountains are well known for their lush forests of tall pine trees, but there are many other types of plants that live here. Deep-rooted chaparral covers the southern face of. the San Bernardino Mountains.
California Lilacs, or Ceanothus, are some of our most fragrant and colorful shrubs here in California. They are also evergreen and very drought tolerant. The myth of Ceanothus being short-lived is primarily spread by incompetent gardeners that insist on drip irrigation, summer water and soil amendments. Drought tolerant California native plants hate all three (except irrigation the first summer). Expect a 20-25 year life from your Ceanothus in most gardens. We have many Mountain Lilacs in the ground here that still look good after thirty years.
