Each year we scour our seed sources to find interesting perennial plants to grow. Our perennial singles range from well known favorites to some truly rare selections. All are first year plants with strong root systems, most will bloom this year, and will certainly be magnificent their second year. Pots are 4" square with a deep rooting zone, ready to grow and thrive for seasons to come.
