H5: Cool Temperate Plants

H5 plants are adapted to cool temperate regions, enduring temperatures as low as -15°C (5°F). They survive harsh winters and thrive in areas with distinct seasons. Think of hardy perennials like Hostas, Daylilies, and many types of ornamental grasses. These plants are the backbone of temperate gardens, providing reliable greenery and blooms year after year, even in the face of winter's icy grip.
