No. 4.
It will be necessary to go over the beds every day or two and remove all dead or dying leaves. Neatness is an item of the greatest importance in this phase of gardening, or any other, for that matter.
No.5.
Large plants can be used in the centre of any of these designs, if one cares to do so, with very good effect. For this purpose we have few plants that will give greater satisfaction than the Dahlia. Scarlet Salvia would be very effective if yellow Coleus were used about it, but it would not please if surrounded with red Coleus, as the red of the plant and the red of the flower would not harmonize. A Canna of rich, dark green would make a fine centre plant for a bed in which red Coleus served as a background. One of the dark copper-colored varieties would show to fine effect if surrounded with either yellow Pyrethrum or gray Centaurea.
No. 6.
Ageratum, with its delicate lavender-blue flowers, can be made extremely attractive in combination with yellow Coleus. A pink Geranium surrounded with gray Centaurea would be delightful in the harmony that would result from a combination of these colors.
