Plants that bloom in November in Zone 6 with white flowers

Annual Vinca

Glossy-leaved heat champion (botanically unrelated to true Vinca minor) that blooms through humidity that wilts everything else.

Aster

The grand finale of the garden season. Essential for fall pollinators.

Chrysanthemum

The fall icon. Mounds of color when everything else is fading.

Fountain Grass

Arching, bottlebrush plumes that catch the light. Movement in the garden.

Miscanthus

Tall, graceful plumes that persist through winter. Living architecture.

Pentas

Star-shaped flower clusters that hummingbirds and butterflies hit on every pass. Blooms nonstop in heat that stops impatiens cold.
