The Hardiness Zone

Know Your Zone.

Not everything at the garden center deserves to come home with you. The Hardiness Zone is an opinionated plant encyclopedia built for gardeners who are tired of recycled advice, sponsored recommendations, and "top 10 easy plants" listicles written by people who've never grown them.

No affiliate links. No nursery partnerships. No sponsored content. Just honest reviews from someone who has actually put these plants in the ground and watched what happens.
