Seeds of Plants for Rock Gardens 
Being frequently asked to recommend seeds of plants not necessarily alpines—suitable for use 
in American rock gardens, we have compiled the following lists for ready reference. All those 
offered are of easy culture and can be relied upon to give greater general satisfaction than is 
usually obtained with the rarer and more difficult alpines. 
While the veteran rock gardener may decry the use of annuals in the rock garden, we stress 
their utility for making a quick showing either in temporarily replacing losses or for Immediate 
effect in newly constructed rock gardens.
