The Fundamentals: Window Box Plant Selection

Successful window boxes depend on a few key design principles--variety, texture, and balance. Let's break down the unbeatable formula for creating high-impact window displays.

1. The Thriller, Filler, and Spiller Formula

A time-tested approach when planting window boxes is the thriller, filler, and spiller method. This technique ensures a visually dynamic arrangement:

Thrillers: Tall, upright plants that add height and drama.
Fillers: Rounded or mounding plants that provide fullness.
Spillers: Trailing varieties that gracefully cascade over the box.

2. Right Plant, Right Place

Sun, shade, wind, and watering habits all influence which plants will thrive. Choose varieties suited for your window's conditions for minimum maintenance and maximum impact.
