Perennial Flowers are the hardy, permanent ones that live for years. In frost-free sections, seeds may be sown at almost 
any time of the year; in mild climates or in localities where winters are not too severe, seeds may be sown in the fall—the 
earlier the better, so that plants will be of good size before freezing weather sets in. After the ground is frozen hard, cover 
the bed with a light mulch of straw or strawy manure to prevent the plants from being heaved out by alternate freezings and 
thawings. Cultural directions are given on every bag. The Burpee leaflet, “Perennials from Seed,’’ sent Free upon request.
