Campanula thyrsoides reaches approximately in height. It is a herbaceous erect and perennial
flowering plant with a showy dense
inflorescence with up to 200 bell-shaped pale yellow flower. The stem is densely leafed, the basal leaves are elongated lanceolate and the stem leaves are tongue-shaped. The cycle of the plant is biennial (in the first year of life the plant completes its vegetative development, in the second it blooms and bears fruit), while the buds are placed at ground level. Flowering time generally lasts from July to August, but sometimes as early as June. These plants are
hermaphroditic. Pollination occurs through insects (entomogamous pollination) or it is
autogamous. Each capsule fruit contains around 120 to 180 seeds. The dissemination of seeds is barochoric. ==Bibliography==
