I am going with Crocus. http://en.wikipedia.org/wiki/Crocus
They bloom very early in the spring
One spring flowering plant that starts with "Cr" is crocus. Crocus plants are known for their vibrant, cup-shaped flowers that bloom early in the spring, often signaling the arrival of warmer weather.
The prairie crocus was designated as Manitoba's provincial flower in 1906 due to its significance and beauty in the region. This delicate purple flower is one of the first to bloom in the spring, symbolizing renewal and resilience in the harsh prairie environment. Its selection reflects the province's natural heritage and the importance of native flora to the identity of Manitoba. The prairie crocus is also celebrated for its role in local ecosystems and its cultural significance to Indigenous peoples.
Daffodils and tulips are popular flowers that bloom during spring.
Bluebells bloom in the spring.
Pasque flowers typically bloom in early spring, around March or April, depending on the region. They are one of the first flowers to bloom in the spring and can be found in a range of colors from deep purple to pale pink.
Fall is the best time so bulbs have the winter to be dormant then bloom in the spring. plant in the spring and they will come up but might not bloom
Crocuses are the first perennial to bloom in most parts of this country. They bloom in February. Tulips, Daffodils, Grape Hyacinths, Snowdrops also bloom in March, and the fuzzy buds on pussywillows are seen in mid March. Unless you are in a desert climate (Arizona, Southern California, etc.) or subtropical climate (Florida) you will only see bulbs blooming before Spring.
The bloom of a flower is the flower its self.
Most cherries (Prunus) flower in Spring with a few eceptions that flower though the Winter.
Not all flowers bloom in the spring those that do so largely because they need to set seed and fruit to the side
