Landraces (heritage plants, heriloom plants, native plants) are part of our living cultural heritage. Their properties reflect the earlier cultivation history of the plants and the culinary values of the past. Their appearance speaks of the aesthetic values that the people who grew country plants have valued. Finnish landraces have adapted to the extreme conditions of the northern European climate. For this reason, there are many more remaining landraces of grasses, barley, oats and rye in Finland compared to many other European countries. The landraces adapted to Finland's northern conditions are unique and belong to our national cultural heritage. Landraces are endangered because new cultivation methods have displaced them. The introduction of new high-yielding varieties and the legislation on the seed market limit their use.
Landraces should be protected and saved for future generations. The threat is urbanization, increased construction and destruction of old residential areas to make way for new ones. With new construction and the desolation of the countryside, the old gardens and their rich variety are disappearing. Modern people prefer smooth, rich, easy-to-maintain lawns, annual imported plants, plant knowledge and care skills are often lacking. Today, the preference for imported plants is taking over the field from landraces, half of woody and perennial plants are foreign species. Landraces have adapted to our climate, they are winter-hardy and their resistance to diseases is better than imported plants. In terms of the preservation of landraces it would be good if seeds were collected from one's own plants and distributed to neighbors, relatives and acquaintances. You should also tell about the importance of preserving the genetics of plants.

During the 19th century Finland had a large export of caraway (Carum carvi) to other European countries. However, caraway was not cultivated at fields but seeds were picked from semi-natural meadows. Here is a picture from the begining of 20th century on how seeds are being cleaned.
All plants that are reproduced by seeds are pretty safe storaged in genebanks. The reproduction of seeds should be carried out locally in the same climatic zone from where it came. This is not the case nowadays and this may be a risk for our food security. Some plants cannot be saved as seeds - they may have tubers or reproduce via their root system. You have to keep them growing in order to save them. In the following we look at three example och such plant crops - onions, potatos and hop:

In NordGen, the Nordic gene bank there is preserved a lot of Finnish grains and other field crops. There is 98 barleys, 96 rye, 28 wheat, 25 oat, 8 buckwheat and 27 broad. In addition there is a lot of old sorts (cultivars).

Seed saving of heritage ornamental plants has mainly been done by the Finnish seed saver organisation. Some ornamentals are also a part of the genetic plant resource program.
