Recommended cold-hardy plants that can be grown even in severe winter cold

In the cold winter, when most plants enter dormancy, some plants can still show astonishing cold tolerance, remaining full of vitality even in severe cold. So, which plants can withstand the test of severe cold?

Roses:Roses are one of the plants with relatively strong cold tolerance. The cold tolerance of different rose varieties varies, but most varieties can withstand low temperatures of minus 10 degrees to minus 20 degrees. Roses are widely cultivated in China and can overwinter outdoors in many places. In winter, roses enter dormancy. At this time, fertilization should be reduced to avoid burning the roots, and withered branches and leaves should be pruned to keep the plant tidy. Roses have strong adaptability and are not only cold-tolerant but also drought-tolerant. They can be planted in the ground or in pots and are one of the most beloved flowers.

Lilies:Lilies are also cold-tolerant plants and can survive in low-temperature environments, but to ensure their healthy growth, certain protective measures are still needed. Before winter arrives, lilies should be pruned by cutting off yellowed leaves to keep the plant tidy. At the same time, if the plants are too dense, they can be thinned appropriately to improve ventilation. In winter, a thick layer of fallen leaves or wheat straw can be spread at the base of and around the lilies to increase the soil's insulation. In areas with lower temperatures, consider moving lilies indoors and providing appropriate light and humidity to protect them from cold damage. In addition, lilies need less water in winter, but the soil should still be kept slightly moist to avoid drought.

Astilbe:Astilbe is a cold-tolerant and shade-tolerant perennial flowering plant with strong adaptability to the environment. It can tolerate low temperatures of around 6 degrees and can even survive in environments of minus 10 degrees or more. However, when growing astilbe in cold regions, cold-protection measures are still needed. In warm southern regions, astilbe can overwinter safely outdoors, but attention should be paid to summer shading and water management. In northern regions, astilbe should be moved indoors or into a greenhouse for care in winter; for those planted in the ground, soil can be mounded at the base or covered with straw, leaves, and other insulating materials. When winter light is weak, the light duration should be appropriately increased to promote plant growth.

Lavender:Although lavender is usually associated with warm summers, some lavender varieties can survive in cold environments. For example, French lavender has relatively strong cold tolerance and can overwinter safely at low temperatures of minus 10 degrees. In winter, lavender enters dormancy. At this time, watering should be reduced to avoid root rot, and withered yellow branches and leaves should be pruned to keep the plant healthy and tidy.

Panicle hydrangea:Panicle hydrangea is a highly ornamental cold-tolerant plant that can survive at low temperatures of minus 20 degrees. Its flowers have a unique shape, like conical hydrangea blooms, with rich colors ranging from white to pink and blue. In winter, the flowers of panicle hydrangea gradually fade, but its branches and leaves still maintain green vitality. At this time, withered flowers and branches and leaves should be pruned to keep the plant tidy and beautiful.

These cold-tolerant plants can not only survive the severe winter but also add color and vitality to the winter garden with their unique charm and vitality. They are gifts from nature, guardians of the winter garden, and indispensable beautiful presences in our lives. Let us cherish these cold-tolerant plants, care for them attentively, and let them bloom with even more brilliant splendor in the cold season.
