A DAHLIA HEDGE IN THE ANDES. 
{Dahlia maxonii Safford; S. P. I. No. 49757.) 
The common tree dahlia (Dahlia maxonii) of Central America and northern South America is 
often used to form hedges. The one here shown is in the Andes of Colombia, near Facatativa. 
When well grown this species reaches 18 feet in height, and it occurs in several varieties, of 
which the principal ones are single and double pink and single and double white. It requires 
a long growing season and is not suitable for cultivation in the eastern United States. It may, 
however, prove of great value to dahlia breeders in this country. (Photographed by Wilson
