Ornamental roses and thorns collection suitable for growing in Lithuania

A collection of the most ornamental roses and thorns suitable for cultivation in Lithuanian conditions, representing the diversity of ornamental traits of roses.

Thorns and roses (Rosa L.) are plants of the rose genus (Rosaceae). The wild species of the genus are called thorns and the cultivated species are called roses. The genus contains about 350-400 species and more than 10000 varieties. Wild thorn species are used as rootstocks, some are planted in plantations, and some are also of industrial importance. The rose petals are used to produce rose oil and the fruit to produce vitamin preparations. Cultivated roses, also known as garden roses, are grown as ornamental plants.

Roses were introduced in Lithuania in the early 19th century. In 1820, the botanist J. Strumila mentions some thorns and cultivated roses that can be grown in Lithuania. In the interwar period, roses were cultivated in manor parks, in botanical gardens and in some places in nurseries. Roses were also cultivated in the Vingis section of the Botanical Garden: in 1928, the French rose (Rosa gallica) was mentioned, in 1953 - 8 species of thorns, and since 1969 the range of cultivated roses has been expanded, but many of the varieties did not survive the cold winters, and in 1977, only 60 varieties were left in the open ground. The rose exhibition in Kairėnai was started in 1996 and the rose garden in the Vingis section was re-established in 2000.

At the 14th International Horticultural Congress, the American Rose Society divided roses into groups according to the variety's main characteristics - its ornamental and biological qualities.

There are three main major groups: species (thorns), ancient roses (groups existing before 1867, such as French, Damask, White-flowered, Moss, Bourbon, Remnant, Portland, Thistle), modern roses (groups that emerged after 1867, when one of the first hybrid tea roses, 'La France', was developed. The date of introduction of this variety is used to distinguish the ancient garden roses from the modern ones).

VU Botanical Garden aims to create a collection of ancient and modern roses that are the most suitable for cultivation in Lithuania. The most resistant varieties to diseases, pests and frost are selected. Varieties are also selected for their ornamental qualities, flower color, flower shape and bush size. The Vingis section currently grows 150 varieties (550 bushes) of the main rose groups (tea hybrid, polyanthus, floribunda, miniature, modern shrub), which bloom almost continuously until late autumn, and in Kairėnai, next to the linden tree avenue of the old park, 80 names of ancient roses, 79 modern shrub roses, and 16 varieties of polyanthus roses, are grown in a 1.5ha plot.
