How to grow hardy plumbago

When to plant hardy plumbago

Hardy plumbago (dwarf plumbago) is a low, spreading groundcover with gentian-blue phlox-like flowers over a long bloom from mid-summer into fall (NC State) and bronze-red fall foliage. Plant 10 to 16 inches apart in spring in well-drained, dry-to-slightly-moist soil in full sun to part shade; it spreads aggressively by rhizomes and benefits from a light winter mulch in colder zones.

Hardy Plumbago is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
