Seed productivity of 22 early flowering plants of the natural flora of the Kamensky geobotanical region, introduced into the culture and used in landscaping, has been established. It was shown that the actual average seed productivity of one individual of various plant species varies from 12 to 373 pcs., And the maximum - from 20 to 448 pcs. seeds, which is 10 to 90% of the potential. In most species, high actual seed productivity is combined with high potential productivity. Field germination of seeds of all plant species was higher when sowing with freshly harvested seeds within 5-14 days after ripening. Storage of seeds at a temperature of 18,0-20,0ºС followed by sowing them in the spring led to a significant decrease in germination.
