Among all the variety of garden perennials can be identified a special group - bulbous flowers. Their name comes from the fact that under the ground they have bulbs - storage of nutrients. After the flowering season ends, the ground part of the plant dies off, but the bulbs remain. They simply go into the resting phase, lasting until the next season.
Not all bulbous plants are able to survive in winter in the open ground. Many of them need to be excavated and transported annually for storage in more suitable conditions.
But there are in nature and bulbous perennials, which hibernate in the open ground. Such winter-hardy species include crocuses, many kinds of tulips, lilies, daffodils, hazel grouses , daylilies. However, with severe and snowless winters, they still need to be covered with sawdust or chips for reinsurance from freezing.
Bulbous plants hibernating in the open ground
Flowers, wintering in the open ground, are called classical perennials. They are able to live in one place without a transplant for 3 or more years and at the same time not lose their attractiveness. On the contrary, they only increase the number and size of flowers year after year, becoming more and more decorative.
But even for such beautifully flowering perennials, hibernating in the open ground, there comes a time when they need to be transplanted. Usually at the age of 5-6 their development is gradually suspended, the soil around them is depleted even under the condition of regular feeding. In addition, bacteria, fungi and microbes multiply in the soil, which do not contribute to the continuation of a beautiful flowering.
The most common perennials wintering in the ground
In addition to bulbous, there are still perennials, grassy, with succulent stems and leaves (succulents), with wintering overhead creeping stems, with dying maternal organs and wintering offspring, and so on.
More often than not, gardeners grow the following perennials on their plots:
- Astilba - the rhizome plants that are unpretentious in their care, wintering in the ground and flowering from the beginning of summer to the beginning of autumn;
- anthemis - beautiful perennials, decorated with vegetation with bright flowers and lace leaves;
- rudbeckie - unpretentious and frost-resistant perennials with beautiful bright colors;
- irises - refer to herbaceous perennials, which quietly hibernate in the ground under the snow;
- Lupines - effective and undemanding perennials, well hibernating in the open ground;
- Tulips - the first messengers of spring, the bulbs of which perfectly tolerate wintering in the ground;
- daylilies - a multicolored flower culture, planted mainly along the curbs, well tolerates wintering in the open ground.
Proper care for perennials
What are good perennials, hibernating in the open - so it's unpretentious. But some of them still require the adoption of preparatory measures for the forthcoming winter. To such measures
For the majority of perennials, winters without snow are especially dangerous. Under such conditions, even the most resistant plants can freeze. Therefore, in order to avoid their loss, it is recommended to cover the flower beds with cover material. This is suitable for spruce lapnik, peat, sawdust, dry leaves and humus.
It is especially important to take care of young plantations. Cover the underground parts of plants remaining in the ground after the end of the growing season, it is necessary during the first established frost.
