Morning Glory Care: Watering Tips and Perennial Potential in Maryland

Your variegated morning glory is thriving in Maryland’s intense summer sun—these Mexican natives love heat! Here’s how to keep it happy and encourage its return.

Watering in Hot Sun

• In-ground: Water deeply once a week if no rain. Morning glories have deep roots once established.
• In containers: Check daily; water morning and evening when temps exceed 90°F. Pots dry out fast.

Will It Come Back Next Year?

Morning glories are annuals in Maryland (zone 6-7), but they readily self-seed. Allow some pods to mature and drop seeds in fall. You’ll likely see volunteers next spring. The variegated ‘Flying Saucers’ (purple/white) often comes true from seed. Look for seeds from reputable sources like Seeds of Change or Thompson & Morgan.

Bonus: Hummingbird Magnet

The tubular flowers attract hummingbirds beautifully. Deadhead spent blooms to prolong flowering, but leave a few pods for self-seeding.
