Creating attractive outdoor floral displays using planters is easy. People simply need to follow the popular thrill-fill-spill formula for container gardening. This involves choosing a select variety of plants that provide height (thrill), fill the container (fill), and cascade over the side (spill). This catchy-named method of planting, thrill-fill-spill, holds the secret to creating visually pleasing yet dramatic garden effects.

Examples:

Thriller plants are tall, bold, and eye-popping. Depending upon the view of the planter, they are typically placed in the center or toward the back of the planter.

Common examples: Canna lily, Salvia, Dahlia

Filler plants are those which fill the gaps between short and tall plants. They are usually midrange in height and surround the thriller.

Common examples: Begonias, Geraniums, Petunias

Spiller plants are those which cascade over the edges of the container to soften the look.

Common examples: English Ivy, Sweet potato vines, Sedum
