Common cornflower (Thalictrum simplex L.)
It is a perennial herbaceous plant with a creeping rhizome up to 120 cm high. Simple cornflower has a straight stem with double-pinnately compound leaves pressed to it with oblong, wedge-shaped at the base, 3-lobed or whole leaves. The flowers are small, purple, located in the nodes of oblong inflorescences. Anthers up to 2.5 mm long. Pedicels come out 1-2 pcs. from every place. An inflorescence stands out from the leafy part of the stem. Blooms in June-July.
The origin of the name cornflower simple received from the ancient Greek from the words ‘thalos’ (green branch) and ‘icter’ (begging, pleading). The plant is very similar to an olive branch entwined with fluff. Such a branch meant a prayer for protection.

Basil doing – this is a frost-resistant species, blooms from early July to September for 60-65 days. The most decorative and beautiful among the representatives of its kind.
Small cornflower (Thalictrum minus L)
Uniformly leafy perennial plant up to 1 m tall with a short, knotty rhizome. Small basil has a straight or curved smooth stem with alternate leaves. Leaves: lower – trifoliate; medium – petiolate, multi-pinnate; upper – sessile, smaller. The leaf blades are rounded, 3-lobed at the top.

The fruit is a leaflet, with large, oblong seeds.
Yellow cornflower (Thalictrum flavum L)
A perennial plant with a furrowed, erect, evenly leafy stem 60 to 110 cm high. Yellow cornflower has thrice-pinnate leaves, with stipules at the base. Leaflets obovate, sharply serrate, dull above. Root lobes are yellow. Inflorescence – thyroid-paniculate. Flowers on short stalks drooping, small, yellow, fragrant. Blooms in June-July.
Cornflower hybrid (Thalictrum hybrida Elin)
Perennial rhizomatous plant with erect, slightly leafy or leafless stems up to 2.5 m high, red-brown in color and gray-green leaves. The flowers are small, 2-colored, light yellow or light lilac, collected in paniculate inflorescences up to 15 cm long. Basil hybrid frost-resistant, blooms in July.

Basil: cultivation and care
The plant is not whimsical, but the cornflower prefers growing and care in partial shade – in the sun, the color of the inflorescences by the middle of summer, especially in hot, dry weather, turns pale, and yellow undertones appear. In the warm season, it needs abundant watering – with a lack of moisture, the smell of flowers disappears and the flowering period is significantly reduced. The culture is frost-resistant, tolerates frosts in open ground without shelter up to -15°C.
The flower is not picky about the soil, but it develops better and blooms more abundantly in fertile, deeply cultivated and nutrient-rich soil.
All care for the basil consists in timely watering, removing weeds and periodically loosening the soil. Tall varieties (above 1-1.2 m tall) need pruning after the flowering period.
In early spring, it is recommended to feed the plant 1-2 times with fertilizers for blooming garden flowers.
The flower propagates by seeds, cuttings and dividing the bush.
Seeds are sown in open ground in late autumn, before the onset of frost. Seedlings are unpretentious, develop rapidly and bloom already in the 2nd year.
Cuttings are taken in early spring from young shoots with incompletely developed leaves and rooted in open ground. Bushes are divided at the end of April or at the beginning of September and planted at a distance of at least 40 cm from each other.
In dry weather, it is often infested with aphids.
The plant is perfect for decorating herbaceous and shrub borders, planting in large arrays and as solitary plants.
