A tall native perennial with dense clusters of small yellow flowers that bloom in late summer and fall. It is extremely hardy, drought-tolerant, and spreads vigorously, making it excellent for wildflower gardens and naturalizing.

Why grow it

Tall goldenrod outperforms many shorter Solidago species in competitive, open-sun sites where its height (3-5 feet) allows it to dominate without requiring staking. Unlike cultivated ornamentals, it establishes quickly from seed and needs no fertilizer or supplemental watering once established, making it practical for large-scale naturalization where maintenance is minimal. It flowers later than early goldenrod species, extending the bloom window into fall when few native plants flower.

Watch out for

In small gardens or mixed borders, its vigorous spread can overwhelm neighboring plants within a few seasons; division every 2-3 years keeps it in bounds. Deadheading spent flower heads reduces prolific self-seeding if you wish to prevent volunteer seedlings in adjacent areas. Like other tall species, it may lodge or bend under heavy rain or wind in exposed sites without air circulation.
