The Manitoba and British Columbia Floral Emblem stamps were issued on April 28, 1965.
Manitoba
The prairie crocus (Pulsatilla ludoviciana) was adopted as Manitoba's floral emblem in 1906. Manitoba was the first Prairie province to adopt a floral emblem after the prairie crocus was chosen in an informal vote in the province's schools. The prairie crocus is an early spring flower often seen pushing through the last prairie snow. The flower, which ranges from light lavender to bluish purple in colour, has an outer coating of hair to protect it from sudden changes in temperature.
