Hail earliest of the opening flowers! 
Fair Harbinger of vernal hours! 
Who dar'st unveil each silken fold 
Ere Sol dispels the wintry cold, 
And with thy silver leaves display'd 
Spread lustre through the dreary glade.— 
What though no frgarance like the rose 
Tincturing the Zephyr as it blows, 
Thy humble flowers from earth exhale 
To scent the pinions of the gale; 
What though no hues of gaudy dye 
Strike with their dazzling charms the eye,  
Nor does thy sober foliage shew 
Each blended tint of Iris' bow; 
Yet in thy meek unsullied grace 
Imagination's eye shall trace 
The glowing blossoms that appear 
Proudly to paint the vernal year, 
And smiling Maia's blushing dyes, 
And jocund Summer's cloudless skies, 
And Autumn's labors which succeed 
To bid the purple vintage bleed, 
Our hopes anticipating see 
Led on in radiant train by thee.
Henry James Pye
