Ceratostigma (Ceratostigma plumbaginoides), commonly known as Dwarf Plumbago or Hardy Blue Plumbago, is a stunning low-growing perennial groundcover prized for its exceptional combination of vivid cobalt-blue flowers and brilliant autumn foliage color. From late summer through fall, a time when most perennials are winding down, Ceratostigma bursts into its finest display — covering itself in clusters of intense, true-blue flowers while the foliage simultaneously begins its transformation to glowing shades of bronze-red and burgundy. This rare combination of late-season bloom and brilliant fall color makes it one of the most uniquely valuable perennials for the four-season garden.

These Professional Grade 4" plants are grown to the highest nursery standards, delivering well-rooted specimens that establish readily and spread steadily to form dense, weed-suppressing mats. Ceratostigma thrives in full sun to partial shade and adapts well to a wide range of soil types, including dry and rocky conditions. Its spreading rhizomatous habit makes it a natural choice for slopes, banks, front-of-border edging, and underplanting beneath deciduous trees and shrubs.

  • Brilliant True-Blue Late-Season Blooms: Intense cobalt-blue flowers from late summer through fall fill a critical gap in the garden calendar when few other perennials are at their peak, providing vital late-season color.
  • Spectacular Fall Foliage Color: Leaves transform to brilliant bronze-red and burgundy in autumn, providing a stunning simultaneous display of blue flowers against glowing red foliage — a truly exceptional seasonal combination.
  • Tough & Adaptable Groundcover: Spreading rhizomatous habit forms a dense, weed-suppressing mat adaptable to a wide range of conditions including dry soil, rocky sites, and partial shade.
  • Late-Season Pollinator Resource: True-blue flowers provide a critical late-season nectar source for bumblebees, native bees, and butterflies as other floral resources diminish in fall.
  • Low Maintenance & Drought Tolerant: Once established, requires minimal supplemental irrigation and thrives with little ongoing care — an outstanding choice for low-maintenance landscape applications.

These 4" healthy live plants thrive in full sun to partial shade with well-drained soil. Water regularly until established, then reduce to occasional deep watering. Hardy in USDA Zones 5–9; mature height 6–12 inches with a spread of 18–24 inches. Blooms late summer through fall (August–October). Cut back to the ground in late winter to encourage fresh, vigorous new growth each spring.

We use expedited shipping policies to protect plant health and minimize plant stress in transit.  All plants are in transit for only 1-3 days. (This does not guarantee 3-day delivery as orders are not always packed and sent out on the day of your order.) We send out deliveries on a weekly schedule to ensure quick transit times, so your order may not be packaged and shipped until later in the week. For instance, we may hold shipments to avoid weekend delays that keep plants in transit for longer.

All packaging includes eco-friendly material and our shipping methods are tested regularly to ensure plants arrive healthy upon arrival.

Additionally, any delays or damages in shipping are covered by our Healthy Plant Guarantee.

If you're plants arrived damaged, we will happily replace them for free!
