There are a lot of easy-growing, sun-loving flowers that butterflies love. Here's a colorful combination for an 18-inch-long window box that will keep pollinators coming back all summer long. This full window box arrangement combines plants with different colored foliage and flowers, and a variety of textures. The butterflies will keep coming back thanks to the bold purple and yellow blooms.
A: Verbena 'Aztec Purple' — 1
B: Parsley (Petroselenium crispum) — 4
C: Zinnia 'Profusion White' — 2
D: Pentas 'New Look White' — 1
E: Lantana 'Landmark Gold' — 3
F: Calibrachoa 'Cabaret Purple' — 2
'Aztec Purple' verbena has big clusters of rich magenta flowers from spring to fall. This particular variety offers excellent disease resistance, so it's a low-maintenance and worry-free option. We used one plant of this variety in this display for a pop of a different color.
Parsley's (Petroselenium crispum) fullness makes it a good option for edging and filling in containers. Not only does this herb attract butterlies, but the foliage remains harvestable until it frosts in the winter. If you live in warmer climates, it will remain strong throughout winter. We used four plants of parsley in this arrangement for added texture and fullness.
Zinnia 'Profusion White' is an early-flowering selection with good disease resistance and white flowers all summer long. It grows 18 inches tall and 10 inches wide. We included two plants in our window box for a crisp pop of white against the green foliage surrounding it.
Pentas is one of the best pollinator-attracting plants around. It blooms all summer long, even during the hottest weather conditions. The large clusters of starry blooms on pentas are the perfect resting place for butterflies, hummingbirds, and bees. The single plant 'New Look White' pentas in this set-up provides height and eye-catching white blooms for interest.
Lantanas are extremely attractive to pollinators. It's common to see numerous butterflies, bees, and hummingbirds swarming around these plants, drinking up the abundant nectar produced in their small, tubular blooms. The three 'Landmark Gold' plants feature gold-hued blooms and lots of height.
Calibrachoa 'Cabaret Purple' is a trailing selection to 8 inches that tolerates part shade. It grows 12 inches wide and features rich purple trumpet-shaped flowers. The two plants in this window box give a trailing element, adding layers of heights and textures.
