Propagating and Growing Tropical Tree Ferns on the California Coast

摘要

Squeezed between the Pacific Ocean and the coastal mountain range that runs through San Mateo County, Pacifica is located about 20 miles south of San Francisco. With an average rainfall of about 30 inches per year and annual temperatures that range from 45 to 78 degrees, this isn't a place that brings tropical plants to mind— especially in the summer months when this part of the coast is blanketed in thick fog. Daniel and Patricia Yans-ura moved to Pacifica in 1983 and Daniel, interested in paleobotany and primitive plants, started collecting and propagating tree ferns there shortly afterwards.
