Often gardeners choose the most unpretentious flowers for their flower beds. But the trouble is that they can spread very much, drown out other plants. If you do not follow this, then you will have to fight them like weeds later.
Aquilegia
Beautiful blue, white and blue aquilegia bells are able to fill all the space around. Especially if it's a wet, shady place.
The seedlings that sprouted by self-sowing do not retain varietal qualities, therefore it is better to remove them. Aquilegia grows quickly, looks very gentle, but crowds out all other plants, if you do not remove its dried inflorescences.
Calendula
A beautiful and useful perennial is specially grown by gardeners: both as a medicinal plant, and for decoration, and for pest control. But these plants are able to survive perfectly on any soil and without any care. Even a single flower gives many small seeds that have a high percentage of germination.
Therefore, if you do not want to grow one calendula in the garden, watch its distribution. In addition, it is a wonderful siderat. Shrubs can not be weeded out, but simply buried in the ground to increase fertility.
Garden violet
These charming flowers have the ability to spread very quickly around the site. After all, their seeds are carried both by the wind and by insects, in particular, ants. And flowering lasts from April to the end of summer. Therefore, a lot of seeds are formed.
The most active are perennial types of garden violets. They are undemanding and grow rapidly. Their movement can hardly be stopped, unless you remove annual fresh plants that have not yet bloomed.
Goldenrod
Perennial unpretentious plant with high shoots and yellow panicles of flowers. Appreciated for its pleasant appearance, a wide variety of varieties. In cut, it stands for a long time in a bouquet.
But in the garden it is best to plant it behind a fence. If the goldenrod falls on a flower bed, receives care and fertile soil, it grows at a tremendous speed, crowding out all neighbors and quickly filling the territory. It is successfully propagated by both seeds and creeping roots.
May lily of the valley
Small bells of lily of the valley delight the eye in small bouquets, decorate mixborders and flowerbeds. But if you do not follow their distribution, they quickly spread over the territory, drowning out other flowers.
This is due to the long creeping rhizomes. Lily of the valley is undemanding to living conditions, grows well in the shade. Therefore, it is necessary to limit its progress on the site.
Echinacea
This perennial from the aster family is often grown as a medicinal plant. It also serves as a decoration for flowerbeds and mixborders. Echinacea looks decorative. But it quickly spreads by self-sowing, has a very high germination rate and can displace other plants.
This happens especially often if you grow it in an open, bright area and do not follow the formation of lateral roots. Already withered flowers must be cut so that they do not give seeds, and to limit the growth over the territory.
Daisy
Similar to large daisies, nyvnyaki bloom lushly all summer. Once on the site, they grow everywhere. After all, the plant is very unpretentious, blooms for a long time, does not need care, gives abundant self-sowing.
One nyvyanik can give life to 100 new seedlings. Therefore, if you want to grow it on your site, choose terry and large-flowered varieties. The decorative species of the leucanthemum is appreciated for large inflorescences, resistance to any conditions, and longevity in cut. They do not give self-seeding and will not cause so many problems.
Enotera
A bright unpretentious perennial refreshes any corner of the garden in which its yellow buds bloom. But over time, it grows greatly, crowding out the rest of the plantings. Even one bush of this plant is able to fill a vast territory.
After all, evening primrose is distributed both by seeds and with the help of roots. Having dug it out completely, you will still find flowers coming up from somewhere unknown.
All these attractive ornamental crops have the ability to turn into weeds and drown out other plants. Their growth and promotion on the site should be limited.
