Jefferson noted Larkspur blooming at Shadwell in July 1767, thought it suitable for naturalizing at Monticello "in the open ground on the west" in 1771, and sowed seed around his Roundabout flower border on April 8, 1810. This is the hardy annual Larkspur, an attractive relative of the majestic Delphinium, which was not introduced until later in the nineteenth century.

 

Typical Blooming Dates: May - July
