Snapdragons in the Deep South: Why They Fade in Summer Heat and How to Manage

In North Alabama, snapdragons planted last fall bloomed beautifully in spring but are now dying despite daily watering.

Why They Fail

• Snapdragons are cool-season annuals in most of the U.S.
• In the Deep South, they bloom through winter and spring, then collapse in summer heat.
• They are not true perennials; they’re grown outside their comfort zone.

Management

• Replant fresh starts each spring.
• They’ll bloom all summer and late into fall in your climate.
