With this commixture of flower and foliation , you ’re indisputable to have fortune of color and texture . Cherry - red Double Knock Out rose make a beautiful accent in a boundary line or down hedgerow . The orotund peak shape is leisurely to aggregate with spike of snapdragon and angelonia . Tall ‘ Rocket Mix , ’ unlike other snapdragon cultivar , does n’t check blooming in summertime , so you may revel the flowers side by side . Angelonia has a similar spike flower but really gets going when temperature rise . Its flowers last a long time and are practically carefree . Just deadhead spent blooms . Silvery dusty miller adds a nice direct contrast to all the bright colors here and low - growing lily turf makes a majuscule edging plant at the front of the border .
