Growing Black-Eyed Susans in Vermont

Black-Eyed Susans in Vermont's Climate

Black-eyed Susans are native wildflowers that thrive in cold-climate conditions. Plant divisions or nursery plants from spring through early fall. They handle poor soil, drought once established, and cold winters without complaint. Leave seed heads standing through winter for bird food and visual interest.

Soil Considerations for Vermont

Rocky, acidic soils typical of New England. Glacial deposits. Thin mountain soils. Raised beds very popular.

Vermont Climate & Growing Season

Short growing season. Cold winters. Cool summers. Long summer days help compensate. Season extension techniques valuable. Black-Eyed Susans can handle frost well, which is an advantage in Vermont's climate. You can push planting dates earlier in spring and extend into fall.

Growing season length varies across Vermont: Northern Vermont (3b, 4a) has a last frost around May 20 - Jun 5, while Southern Vermont (4b, 5a, 5b) sees frost end around May 5 - May 20.
