In the years 2001-03 investigations on blooming biology, nectar secretion, pollen production and insect foraging of the new genotype Solidago hybrida hort were carried out in Pulawy (Poland). The genotype occurred spontaneously in the collection of melliferous plants at Apiculture Division. The perennial is characterized by short (50-60 cm), stiff shoot with dense leaf arrangement and numerous branches forming star-like inflorescence at the top. The blooming lasts in July - Sptember and is very abundant - 300 thousands of capitula per 1 square m was counted. The sugars weight was 2 - 4 mg per 100 flowers and the pollen weight 1 - 2 mg per 100 flowers. While blooming the perennial is willingly visited by different pollinators. The pollen and nectar collectors of honey bee accounted for ca. 90 percent of the total number of insects. The foraging activity lasts the whole day. At full bloom and in peak flight hours over 40 honeybee forages per 1 square were observed
