What flowers are cold-resistant in winter outdoors

The flowers suitable for winter outdoor maintenance mainly include plum blossoms, roses, forsythias, clematis, and hydrangeas. These flowers can survive in temperatures as low as minus ten to fifteen degrees Celsius. As long as we pay attention to the maintenance methods in our daily care, they can still bloom in the cold winter, offering high ornamental value.

Plum Blossom

Plum blossoms are very cold-resistant woody flowers, generally able to endure low temperatures of -10℃ to -15℃. Plum blossoms planted in the garden can safely overwinter as long as they do not encounter long periods of extreme cold weather.

Although potted plum blossom landscapes are also cold-resistant, if you want them to bloom early, you should move them indoors after entering winter. The temperature should be controlled at 5-10℃, and watering should not be too frequent to avoid overly moist potting soil. Placing the potted plant in a sunny area is more conducive to the plant forming buds and blooming.

Rose

Roses are highly adaptable to the environment and can be planted outdoors in gardens in both the north and south. After entering winter, an extensive pruning of the plant's tangled branches should be performed. Only the main sturdy old branches should be retained, which can produce more new buds the following year.

Potted roses have limited soil in the pot and are somewhat less cold-resistant. Before winter, they should be supplemented with some decomposed organic fertilizer or slow-release fertilizer to increase the plant's cold resistance. After the leaves fall, the plant should be pruned and moved to a sheltered area where it can receive sunlight. You can also cover it with a plastic bag for insulation.

Forsythia

Forsythias are very cold-resistant. It is suitable to plant forsythias in the garden, and they can normally overwinter in temperatures below minus ten degrees and bloom early in the following spring.

Whether it's a forsythia planted in the ground or in a pot, no pruning should be done after entering deep autumn, as it may easily cut off some flowering branches.

Before winter, more phosphorus and potassium fertilizers should be added to promote the growth of flower buds. After entering winter, the potted forsythia can be moved indoors. The temperature should be controlled above 15℃, and sufficient light should be provided. This way, it can bloom during the Spring Festival, looking particularly beautiful and festive.

Clematis

Clematis, like roses, is very popular among flower enthusiasts and is even known as the "Queen of Vines". This type of vine not only has beautiful flowers but is also highly cold-resistant and can overwinter outdoors in winter.

In deep autumn, some multi-element compound fertilizers can be applied to make the plant grow stronger and prepare for overwintering. Even after the leaves of the plant gradually fall off, its vines remain fresh.

Of course, when the temperature is extremely low and often hit by strong winds, its vines can easily dehydrate and dry up. However, as long as the roots are still intact, it can grow new branches and form flower buds in the spring.

Hydrangea paniculata

There are many varieties of hydrangeas, such as large hydrangeas and panicled hydrangeas. In fact, hydrangeas are also very cold-resistant, including large hydrangeas, which will not be frostbitten after brief exposure to freezing temperatures.

However, when kept in low temperatures for extended periods, it will affect the plant's normal growth and flowering the following year. Panicled hydrangeas are even more cold-resistant, with a minimum cold tolerance of below minus twenty degrees, making them very suitable for planting and观赏 in the north.
