Did you know that many of our founding fathers, including George Washington and Alexander Hamilton, had gardens on their estates and were deeply invested in the various plants and flowers they grew? This makes sense when one considers how a thriving, self-sufficient landscape reflects the thriving, free society they hoped to create.
While we can only speculate as to the content and arrangement of our founders’ flowers, history has recorded the types beautiful summer flowers available to the new nation. Unlike some of our greenhouse exotics today, flowers of the past were hardy, hardy plants that could overcome problems in their growing environment in a way that mirrored the American sands.
What better way to celebrate our nation’s historic courage and perseverance in the face of challenges than to add some of these amazing plants to your own landscape? We’ve compiled a short list of 8 blooming beauties that our founders might well have included in their own gardens.

Twinleaf is a North American perennial with small white flowers that appear on stems in early spring, before the leaves have expanded. The unusual capped seeds ripen in early June and often go completely dormant in the summer.
Twinleaf prefers shade and makes a great groundcover in a suitable location. It offers lush green leaves and flowers, small white flowers that open in early spring before the leaves. Easy to grow, dicots are not for the faint of heart as they can take up to 8 years to flower from seed.
