Cosmos is an annual flowering plant belonging to Compositae. It is a short-day plant which likes sunshine. It is easy to cultivate the flower as it has a strong vitality. Cosmos remains fresh even in late autumn when other flowers are gone. So it is planted by the roadside and railway and in the station yard in many cases. It is also planted in gardens and flower beds for afforestation and at homes and institutions for decoration of their walls and fences.
Koreans, too, love very much the cosmos with strong vitality and ornamental value and plant and cultivate it everywhere. Researches into cosmos are made as well. The Pyongyang Floricultural Institute, a flower research and production centre, acclimatized cosmos from other country in the past and made researches to breed new varieties of cosmos.
In the course the institute has bred different kinds of new varieties of cosmos and registered them as national varieties. There are different varieties of cosmos including early-variety ones Nos. 1, 2, 3 and 4. It was not easy to acclimatize multicoloured cosmos to the conditions of Korea and make a research into a variety of cosmos with large flowers of one or two colours. But the researchers buckled down to researches with one mind to make the whole country beautiful with flowers in full bloom. They made repeated researches, pooling their wisdom. As a result, they could complete the research into the early-variety cosmos No. 1 in Juche 93 or 2004. Afterwards, too, they bred new varieties of cosmos with flowers almost twice larger than the previous ones, showing deep pink, white or various colours. They also succeeded in acclimatizing cosmos with tubular flower petal or a short cosmos.
Section Chief Ri Su Ryon has this to say:
"Flowers make the people more pleasant for their beauty and sweet fragrance. So all the researchers of my section are devoting their wisdom and zeal to research a greater number of beautiful flowers giving unusual emotion to the people."
