Alberta [SEP] Flora
In central and northern Alberta the arrival of spring is marked by the early flowering of the prairie crocus anemone; this member of the buttercup family has been recorded flowering as early as March, though April is the usual month for the general population. Other prairie flora known to flower early are the golden bean and wild rose. Members of the sunflower family blossom on the prairie in the summer months between July and September. The southern and east central parts of Alberta are covered by short prairie grass, which dries up as summer lengthens, to be replaced by hardy perennials such as the prairie coneflower, fleabane, and sage.
