Introducing 'String Theory,' the newest addition to the Proven Winners lineup, offering a fresh take on the beloved threadleaf Amsonia. This compact variety presents a charming alternative to the traditional Amsonia hubrichtii, perfect for gardens of any size.

During the late spring, 'String Theory' graces the garden with its delicate light periwinkle blue flowers, creating a captivating contrast against its rich, dark green foliage. Unlike some other Amsonia varieties that may experience leaf discoloration, 'String Theory' maintains its vibrant foliage throughout the summer months.

With its slightly delayed blooming period compared to 'Storm Cloud,' 'String Theory' extends the flowering season, ensuring enduring beauty in the landscape. Its tidy growth habit and durability make it an excellent choice for gardeners seeking a fuss-free yet visually stunning perennial addition.
