In the largest pot, working from back to front and tallest to shortest, densely plant 'Liberty Classic Yellow' snap-dragon, 'Bouquet Rose Magic' dianthus, and 'Tickled Pink' veronica. Place 'New Look' dusty miller and 'Lemon Ball' sedum in the front to trail over the edge. Pack a powerful, single-note punch in the two smaller pots by planting 'Supertunia Vista Bubblegum' petunia in the midsize container and more sedum in the smallest.
