Variegated Plumbago

Plumbago auriculata 'Variegata'

shrub

Variegated Plumbago is an ornamental shrub renowned for its striking foliage featuring cream and green variegated leaves, complemented by delicate sky-blue flowers. This tropical to subtropical plant produces clusters of soft blue blooms throughout warm months, making it an excellent choice for borders, containers, and landscape color. It's a vigorous grower with a semi-trailing or mounding habit that can be shaped and trained.

💧

Water: Moderate watering; keep soil consistently moist but not waterlogged. Water deeply during growing season, reduce watering in winter. Drought-tolerant once established but flowers better with regular moisture.

📏

Spacing: 36 inches

📅

Days to maturity: Flowers begin appearing 60-90 days after planting; full mature size reached in 12-18 months

🌱

Planting depth: Plant transplants at same depth as nursery pot; surface sow seeds and keep moist until germination

Soil

Type: Well-draining loamy soil with organic matter

pH: 6.0-7.5

Growth Stages

Seedling/Establishment

4-6 weeks

Young plant with small leaves showing early variegation. Growth is slow initially as root system develops.

Provide bright indirect light, keep soil consistently moist, maintain warmth (65-75°F), protect from strong winds. Avoid overwatering which causes root rot.

Vegetative Growth

6-12 weeks

Plant develops multiple shoots with increasingly variegated foliage in cream and green patterns. Stems become woody and branch structure forms.

Gradually increase light to full sun. Begin light pruning to encourage bushiness. Feed with balanced fertilizer monthly. Increase watering as growth accelerates.

Pre-flowering

3-4 weeks

Plant reaches mature size with full variegated canopy. Leaf nodes swell slightly as flowers begin forming.

Continue regular fertilizing, switch to higher phosphorus fertilizer to encourage blooming. Maintain consistent moisture. Prune any leggy growth.

Flowering

8-16 weeks (extended in favorable climates year-round)

Abundant clusters of delicate sky-blue tubular flowers appear at branch tips. Blooms attract pollinators and continue for extended period in warm weather.

Maintain even moisture and full sun exposure. Apply bloom-promoting fertilizer every 3-4 weeks. Deadhead spent flowers to encourage more blooms. Reduce watering slightly in evening to prevent mildew.

Dormancy/Winter Decline

2-4 months

Flowering slows significantly. Plant may lose some leaves in cold climates. Growth nearly stops.

Reduce watering considerably. Stop feeding. In zones below 8b, bring container plants indoors to warm location (55-65°F). Prune back hard in spring before new growth emerges.

Harvest Tips

Variegated Plumbago is grown for ornamental flowers and foliage rather than harvest. Deadhead spent flower clusters to encourage continuous blooming throughout the season. Cut back hard in late winter or early spring to maintain shape and promote vigorous growth. Take semi-hardwood cuttings in summer for propagation.

Fun Facts

🌱 The variegated form is less vigorous than the solid green species (Plumbago auriculata), but the cream-colored leaves become more pronounced with more sunlight exposure.
🌱 The name 'Plumbago' comes from the Latin word 'plumbum' meaning lead, referring to an old belief that the plant could cure lead poisoning.
🌱 Variegated Plumbago can be trained as a small tree or espalier on a fence/trellis, making it very versatile for garden design.
