Plants that bloom in November in Zone 9 with purple flowers

Bougainvillea

Explosive cascades of papery magenta, hot pink, or coral bracts that smother walls, fences, and pergolas with nonstop color from spring through fall in zones 9 to 11.

Chrysanthemum

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

Lantana

Multi-colored flower clusters that bloom relentlessly in brutal heat.
