Blue Plumbago Plant Care

The Imperial Blue Plumbago thrives in full sun with well-drained soil and steady moisture while establishing. Feed lightly in spring and trim after bloom flushes to keep plants dense and floriferous. In cooler zones, grow in containers you can roll into bright, protected spaces for winter.

Sunlight: Provide full sun (6–8+ hours daily) for the heaviest bloom production.

Watering: Keep soil evenly moist while establishing; once rooted, water when the top inch dries.

Soil: Prefers well-drained sandy or loamy soils.

Fertilizer: Apply a light, balanced feed in spring to encourage flowering.

Hardiness: Perennial outdoors in USDA Zones 8–11; annual or patio plant in cooler regions.

Light: Place in the brightest indoor location or supplement with grow lights.

Watering: Reduce in winter; keep soil lightly moist, not waterlogged.

Container: Ships in a 1 or 3 Gallon nursery pot; transition to a decorative container with drainage.

Temperature: Maintain above 50°F indoors during overwintering.

Overwintering: Prune lightly before bringing indoors to control size and encourage compact regrowth in spring.

Bloom Cycle: Flowers continuously from spring through fall.

Pruning: Shear after bloom flushes to maintain form and encourage repeat flowering.

Propagation: Easily propagated from softwood cuttings.

Pests: Generally resilient; may attract mealybugs or aphids in containers.

Winter Care: Mulch around base in Zone 8; overwinter indoors in cooler climates.

Expert Grower’s Tips for Blue Plumbago

Advice from our growing experts

More Sun = More Blue

More Sun = More Blue

Give 6–8+ hours of direct sun to maximize clusters and color intensity. Partial shade reduces bloom density and makes plants leggier.

Shear for Repeat Flushes

Shear for Repeat Flushes

A quick trim after blooms fade redirects energy into new flowering shoots within weeks. Maintain a rounded, dense habit for hedge or border use.

Container Advantage

Container Advantage

Use well-draining mix in large pots for balcony or patio displays. Containers warm quickly, boosting spring growth and extending fall color.

These tips are based on 30+ years of professional growing experience at our Florida nursery.

This shop has the most fantastic, healthy, gorgeous plants. I am a repeat customer and have never been disappointed. In fact the plants have always exceeded my expectation and plants are often much larger than expected. Packaging is some of the most professional I've seen, with not one leaf damaged. I'll be back for more.
