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 with unsponsored takes, honest reviews, and tools for gardeners who want real information — not marketing copy.

What You'll Find Here

The Root Report — Honest, opinionated plant reviews. Every plant rated from criminally underrated to outright fraud.
Pile O' Databases — Filterable plant databases for coneflowers (echinacea), bee balm (monarda), coreopsis (tickseed), and agastache (hyssop).
Greenhouse Games — Seven daily plant-themed games: Rootwork, Deadhead, Thistl, Common Ground, Smarty Plants, Sproutl, and Stump'd.
Overgrowth — Deep dives, variety breakdowns, and the plant diagnosis tool.
Dry Goods — Shirts and gear for gardeners who've heard enough from the garden center.
