their tall spikes of bloom well above the purple Phlox-Deutzia 
that does so well here. This pageant lasts well into July, only to be 
replaced by Salvia leucantha, Salvia farinacea and Salvia azurea 
with their tall spikes of orchid and sky-blue that harmonize so 
beautifully with the Helenium autumnale and Riverton Gem. The 
stately Goldenglow, with its bright yellow clusters of flowers, is 
a background for Physostegia virginiana. On into September and 
October, with clumps of Ageratum, annual Klondyke Cosmos, and 
Michaelmas Daisies. As we reach late October and November, the 
garden retires in a blaze of glory, supplied by the wonderful Chry¬ 
santhemums in rose, pinks and crimsons, yellows and bronzes. 
Someone has said “There are rich rewards in a perennial garden 
and much quiet joy.” 
So much for the perennials so generous and colorful from early 
spring until autumn, but what of the annuals? These are neces¬ 
sary, too. We all love them and could not have a garden without 
them. (See page 55.) 
Skillful planning will enable you to use the same ground several 
times so that places occupied by Tulips or any spring bulbs may be 
a blaze of color in the later summer or fall with lovely annuals. A 
bed of Larkspur may be replaced by Zinnias or a bed of early Pop¬ 
pies replaced with Marigolds. These will, in a short time, present a 
mass of color necessary perhaps to complete a picture. Almost 
everyone is familiar with those annuals that grow in our extremely 
hot climate—Cornflowers, Zinnias, Pansies, annual Phlox, Mari¬ 
golds, Lantanas, Nasturtiums, Arctotis, Verbenas, Escholtzias, 
Alyssum, annual Ageratum, tall growing and dwarf Gaillardias, 
Candytuft, Centaureas, Cockscomb, and the biannual Hollyhocks. 
To have a beautiful effect early in the spring with annuals, cer¬ 
tain ones (namely Larkspur, Poppies, Candytuft, and the Cen¬ 
taureas) should be planted in the fall, in late October, in a bed 
that has been well-spaded and fertilized with equal parts of bone- 
meal and sheep manure, or with well-rotted cow manure. 
The following table gives a detailed account of those perennials 
that I have thoroughly tested and found a success in Dallas:
