As the saying goes, "A autumn rain and a cold." It has been raining for several consecutive days recently, and the temperature has dropped a lot. Many flowers and plants that are not cold-resistant, yellow leaves and fallen leaves have entered a low temperature and semi-dormant state. Many flower lovers from Northeast China and Inner Mongolia asked me about the cold-resistant plant that can be planted on the ground. I have also written about many cold-resistant varieties, such as hydrangea , samadhi, rose , clematis , etc. But today I want to introduce to you a plant that is extremely cold-resistant, can bloom in the wind and snow, and cannot die of frozen at minus 20 degrees Celsius - heather .
Heather, an evergreen shrub plant of the genus Azalea family Heather. Its origin is in northern Europe and is the national flower of Norway . As a world-renowned winter flower, heather is widely grown around the world, and many breeders are studying hybrid varieties of heather. Nowadays, there are many varieties of heather introduced to China, with about dozens of them, and they are still being introduced every year.
Because the variety of heather is rich, the heights between different varieties also vary greatly. There are mini varieties that are only 20 or 30 cm tall, and there are also tall varieties that are more than 1 meter tall. Flower lovers who plant pots recommend choosing a shorter type, while flower lovers who plant ground can choose their favorite variety at will.
As one of the main ornamental flowers in winter, heather has excellent cold resistance. Judging from the data, various heather varieties can withstand at least low temperatures of minus 20 degrees Celsius, and some varieties can even withstand low temperatures of minus 30 degrees Celsius. The leaves of heather are needle-like, very similar to those of pine trees. This leaf can remain green all year round and still turn yellow or fallen leaves in the cold winter.
The flowers of heather are very small, but fortunately, they have a large amount of flowers, and a single branch can have dozens or hundreds of flowers. Flowers will bloom between the leaves. The flowers are bright, usually bright colors such as pink, white, and purple, and can also exude fragrance. Whether it is windy or snowy, it will be turned on all winter.
Maintenance points
Haira in my country mainly flowering period from October to March of the following year. If you want to plant it, you should buy it in autumn, otherwise you will miss the time to enjoy the flowers. The low ambient temperature for a long time is conducive to the differentiation of flower buds of heather, so potted flower lovers should not put it in warm indoor planting. Try to ensure that the temperature is below 10 degrees before blooming. From a temperature perspective, heather planting in the north has more advantages than in the south. Winters in the north are colder and longer, so it takes longer to appreciate heather. In areas with too high winter temperatures in the south, heather cannot bloom.
Special attention should be paid to lighting. The light in winter is much weaker than in other seasons, but if heather is to bloom, it must absorb enough ultraviolet rays for photosynthesis . Therefore, flower lovers who plant heather must plant it to the best position in winter. For potted flower lovers, if you have the conditions, try to place it in an outdoor and have good sunlight.
Heather is cold-resistant and freezing, but not heat-resistant. Flower lovers' heather usually dies in summer. Generally speaking, starting from late May, heather will enter a dormant state as the temperature rises. This state will not end until the temperature gradually turns cooler in August. This period is the most vulnerable period for heather. Be sure to keep it from the scorching sun, reduce watering, and keep the environment cool and ventilated.
If you are in the north and want to plant some cold-resistant plants that can bloom in winter, heather is definitely a good choice.
