Early bloomers

"The rain to the wind said,
You push and I'll pelt.'
They so smote the garden bed
That the flowers actually knelt,
And lay lodged--though not dead.
I know how the flowers felt."

In Southern Ontario, coltsfoot flowers in April, often before the last of the snow melts. SHIRLEYTWOFEATHERS.COM.  (The leaves gives this plant its name.  Farther south, these are among the first to pop through the dirt in early Spring, often through snow.)

Daffodils

Around here, the ubiquitous Forsythia colors many gardens yellow in early Spring.
