These plants are characteristic for our region and well adapted to local conditions. They are important parts of the ecosystem, a natural habitat for native fauna.
field poppy (Papaver rhoeas L.) - archeophyte
Cornflower (Centaurea cyanus L.) - archeophyte
acute buttercup (Ranunculus acris L.)
meadow sage (Salvia pratensis L.)
torn bonnet (Silene flos-cuculi (L.)
true pyrethrum (Leucanthemum vulgare)
double feather cosmos
These are often species that do not occur naturally in our flora, characteristic for other climatic zones. They bloom very profusely and for a long time. They may have additional properties, such as drought resistance or higher honey yield.
sea-lionfish (Lobularia maritima)
double feather cosmos (Cosmos bipinnatus)
Prickly eagle (Coreopsis tinctoria Nutt.)
two-colored rudbeckia (Rudbeckia bicolor Nutt.)
borage (Borago officinalis L.)
They are characterized by intense growth and usually increased honey yield. Their seeds are food for wild birds. Mixtures with cultivated species are economical and easy to grow.
common sunflower (Helianthus annuus L.)
canola (Brassica napus L.)
white mustard (Sinapis alba)
buckwheat (Fagopyrum esculentum Moench)
hairy vetch (Vicia villosa Roth.)
Common flax (Linum usitatissimum L.)
Popular balcony plants are usually sterile hybrids, flowering abundantly for long time thus pleasing esthetically, but they do not attract pollinators.
Although they may seem beautiful and useful, they really destroy native nature. Invasive species get to occupy the available niches easily and sometimes very quickly. They turn various habitats of plants and animals into barren monocultures dominated by one alien and hostile species.
As for flowers, the matter is simple - they should be removed. The sooner the easier it is to control them. Among invasive plants most often met are:
Goldenrod (Solidago canadensis L.)
late goldenrod (Solidago gigantea Aiton)
branchy (Erigeron ramosus Walters)
Persistent lupine (Lupinus polyphyllus L.)
