Alders are trees or, more rarely, tall bushes that bloom before they show their leaves, from March to April (almost at the same time as hazel trees). The genus contains 30 (35) species that typically grow in the Northern Hemisphere, in temperate and cold climates across Europe, Asia, Northern Africa and America.

Ragweed is a plant with rough stalks that belongs to the aster family (Asteraceae Dumort). Plants from the genus of Ambrosia do not typically grow in Lithuania. There are, however, two wild species that very rarely and accidentally make it to Lithuania: the common ragweed (Ambrosia artemisiifolia L) and the giant ragweed (Ambrosia trifida L).

Goosefoot is a genus of the Amaranthaceae Juss. family. There are 255 species in the goosefoot genus. About 17-18 of these can be found in Lithuania, but 8 of these are adventive species (wild and accidentally arrived in a new locality). The most widespread is the white goosefoot (Chenopodium album).

The birch is a genus of the Betulaceae Gray family of the Fagales order. The birch genus contains about 120 species, four of which are indigenous to Lithuania. Many introduced species are cultivated for aesthetic reasons and other purposes.

The nettle is a genus of the Urticaceae Juss. family of the Urticales order. Lithuania has two indigenous species of the Urtica genus: the common nettle (Urtica dioica) and the annual nettle (Urtica urens). Urtica cannabina is also cultivated, but rarely.

The plantain is a plant in the Plantaginaceae Juss. family of the Plantaginales order. The plantain (Plantago) genus has over 250 species. Nine of these grow or are grown in Lithuania.

The Artemisia genus belongs to the family of Asteraceae Dumort. The genus has around 400 species. Seventeen of these grow or are grown in Lithuania: 12 adventive (wild and accidentally arrived) and 4 introduced for various purposes. These are perennial or annual grasses, semi-bushes and bushes.

Hazels are bushes or, occasionally, trees of the Betulaceae Gray family. The genus consists of 15 species that can be found in temperate zones of the northern hemisphere. Mostly in eastern Asia and North America. In Lithuania, one of these is indigenous: the common hazel (Corylus avellana) and 6-7 are not widely introduced species.

Lime trees are a genus of the Malvaceae family. The lime genus includes about 45 species, with only one species indigenous to Lithuania, the small-leaved lime, and about 13 are cultivated as introduced species.

The Poaceae (Gramineae) family is very large. This group of plants is composed of 500 genera with over 6,000 species of true grass. True grasses grow all over the world. Different species can be found growing in all types of soil.

The Pinaceae genus is part of the Pinophyta family, which contains 4 subfamilies, 10 genera and 250 species. Pinaceae plants are bisexual plants that usually grow as coniferous tree, more rarely as bushes, and are one of the most economically important genera. Species of two genera, the pine (Pinus) and the fir (Picea A. Dietr.) are indigenous to Lithuania.

The sorrel is a genus of plant that belongs to the Polygonaceae family. These are perennial grasses with grooved stalks and sagittate leaves. About 30 species of sorrel (from the Rumex genus) can be found in Lithuania. Four species are adventive and two are cultivated for various purposes.
