When it comes to creating a garden that bursts with color year-round, selecting the right plants for your hardiness zone is crucial.

This guide will walk you through the best flowering plants for Zone 6, providing expert advice on how to design, care for, and maintain a stunning garden that flourishes in this climate.
Understanding Zone 6: What It Means for Flowering Plants
The USDA Hardiness Zone 6 is known for its cold winters and moderately warm summers. Knowing your zone helps you select plants that are best suited for the conditions your garden will face throughout the year. Zone 6 gardeners need plants that are cold-hardy, able to tolerate freezing temperatures, but also capable of handling the occasional heat waves that come with summer.
