Wildflowers: Interstate 8
San Diego to Pine Valley along Interstate 8
April 27-May 4, 2000

Botanizing at 70 mph is hardly a good way to identify flowers, but traveling on Interstate-8 between San Diego and Pine Valley, one can't help but notice there's a variety of flowers in bloom. On the transect from sea level to foothills and mountains, development begins to thin and the vegetation changes. Near Alpine, at about 2000 feet above sea level, Mission Manzanita (Xylococcus bicolor) gives way to Manzanita (Arctostaphylos sp.; Lemonadeberry (Rhus integrifolia) to Sugar Bush (Rhus ovata); Coastal Sagebrush (Artemisia californica) to Great Basin Sagebrush (Artemisia tridentata), and Ceanothus verrucosus to Ceanothus greggii ssp. perplexans. and there are more wildflowers.
