Greenwood Nursery: Dwarf Plumbago + Ceratostigma (2 Pint Pots)
The 2-pint pot option offers a showy, mat-forming perennial that spreads to form a tight ground cover, suppressing weeds and creating a low green mound through summer. In August, brilliant blue starry flowers appear on wiry branches, with foliage turning a striking dark red in fall. It thrives in well-drained soil and sun, but does not tolerate soggy conditions. Best for hot summer climates and well-drained soils.
Why choose this: ideal for smaller spaces, green roofs, or border edges where you want fast coverage. It’s drought-tolerant and butterfly-friendly. Limitation: less tolerant of wet soils or heavy winter moisture.
Who it’s best for: homeowners with sunny beds or compact spaces seeking reliable blue blooms late in the season and a visually appealing fall color shift.
Greenwood Nursery: Dwarf Plumbago + Ceratostigma (5 Pint Pots)
This larger quantity option is best for creating a more expansive ground cover or mass planting to suppress weeds across larger borders. The plant’s growth remains fast and low, under 1 foot tall, with blue flowers that peak in late summer. Needs well-drained soil and full sun to partial shade for best performance. It is drought-tolerant and deer- and rabbit-resistant, making it reliable in challenging landscapes.
Best for: gardeners aiming for a bold blue display across a wide area, or green roof applications where extensive coverage is desired. Caution: ensure good drainage, as poorly drained soil reduces vigor.
Greenwood Nursery: Dwarf Plumbago + Ceratostigma (3 Pint Pots)
Choose this size for mid-range coverage or for edging along pathways and borders. The plant’s compact habit (0-1 ft) and blue blooms deliver a dependable seasonal color. It performs well in hot summer climates but may be less reliable in winter in cooler zones. It’s drought-tolerant and butterfly-friendly, making it a resilient border plant.
Best for: gardeners with moderate planting budgets seeking quick coverage and a splash of blue. Limitation: winter reliability can vary by climate, so plant in zones 5–9 and protect in cold snaps.

Spacing is typically 8–12 inches between plants.
Best for: designers or big-yard projects needing dense ground cover with consistent flowering. Limitation: handling and planting many small pots requires careful spacing for even coverage.
Buying Guide: Key Considerations
- Light and soil: All options prefer full sun to partial shade and well-drained soil. Avoid wet, poorly drained sites to prevent root rot or slowed growth.
- Bloom timing and color: Expect blue starry blooms in late summer through autumn. Foliage may turn red in fall, adding seasonal interest.
- Height and spread: Most selections stay under 1 foot tall, with compact, mat-forming growth ideal for ground covers and borders.
- Climate suitability: Plants are best in warm to hot summers; winter reliability improves in zones 5–9 but can vary by microclimate.
- Water and maintenance: Drought-tolerant once established; avoid overwatering. Pruning after bloom can encourage a neater habit and more flowering shoots.
- Animal resistance: Described as deer- and rabbit-proof in some listings, which can inform placement in more active gardens.
- Planting strategy: For dense coverage, select larger quantities; use staggered planting to minimize gaps and promote quicker carpet-like growth.
