About Prices on Perennials: 
3 for $1.50 means that 3 of a certain 
kind are sold at that rate; 10 for $4.50 
means that 10 of one variety must be 
ordered to obtain that rate. If less than 
3 of any one variety are wanted and 
an each rate is not given, then divide 
by 3 and add 5 cts. per plant. For 
example, 3 for $1.50 figures out to 55 
cts. each. Because perennial flowers 
look so much better when planted in 
small groups of at least 3 of a variety, 
we suggest that this method be used 
in ordering and planting, and our 
prices are made accordingly.
