Garden cultivation of wild plants. • 



It is well known that certain of our native plants die out in gardens 

 unless in soil similar to that in which they occur naturally. The writer is 

 indebted to Mrs. E. W. Sexton for information regarding attempts to grow 

 the following in ground behind the Marine Biological Laboratory at 

 Plymouth. The soil is over limestone, and varies in reaction from about 

 pH 7-6-8-2.
