Best Dark Blue Plumbago Auriculata Plants for Gardens and Containers
For dark blue-toned flowers, look for Plumbago auriculata sold as “Imperial Blue”; listings describe its blooms as sky blue or vivid cobalt blue rather than guaranteeing a specific shade. The four- and six-plant options suit gardeners planning a larger display, while the two-plant and single-pot options suit smaller projects. These selections are best suited to warm-climate gardens, patios, and containers, with full sun helping support better flowering.

Imperial Blue Plumbago, Lot Of Two
This two-plant listing is best for buyers who want to establish a small grouping without purchasing a larger set. The seller describes a fast-growing perennial shrub with bright-green foliage and sky-blue flowers. Mature plants are listed at about 3–4 feet tall and 2–3 feet wide, making them suitable for a modest landscape accent when given room to spread.
Choose this option if two starter plants fit your planting plan. Regular watering is recommended, with more frequent watering during extreme heat; the listing also describes the plant as moderately drought tolerant. One limitation is that the plants may not be shipped in bloom, so flower color may not be visible on arrival.
Imperial Blue Plumbago In A 4-Inch Pot
This single potted plant is best for a container, patio accent, or small garden bed. Its listed growth habit is mounding and climbing, and it can be trained to cover a trellis. The seller gives a mature size of 3–4 feet tall and 2–3 feet wide, with bright-green foliage and sky-blue flowers.
Full sun is recommended because flowering is reduced in shade. The listing specifies adaptable soil, with well-drained soil preferred, and hardiness zones 8–11. Water regularly during the first few growing seasons; established plants may need occasional watering, especially during drought or extreme heat. Avoid this choice if your growing conditions fall outside the listed hardiness zones and you cannot provide suitable protection.
Imperial Blue Plumbago, Set Of Two Starters
This set is best for gardeners who want two young plants for a compact planting or paired display. Each starter is listed as 4–8 inches and arrives without a pot. The mature shrub is described as sprawling and semi-evergreen, with the potential to scramble over a trellis or fence when given support.
The listing describes dense clusters of vivid cobalt-blue, five-lobed flowers from spring through fall, and nearly year-round flowering in mild climates. Plants prefer full sun to light shade and moderate water; they are described as drought tolerant once established. Because these are young starters without pots, plan to provide suitable planting containers or prepared garden soil.
Imperial Blue Plumbago, Set Of Three
Choose this three-plant set if you want more coverage than a pair of starters provides. The listed plants are 4–8 inches tall and come without pots. Their mature form is described as a sprawling, semi-evergreen mound that can climb or spread over a fence or trellis with support.
The seller describes vivid cobalt-blue flowers in dense clusters, blooming spring through fall and nearly year-round in mild climates. Full sun to light shade and moderate water are listed, with drought tolerance once established. This option is better for buyers prepared to grow young plants; it may not be the right fit if you need an established, flowering shrub immediately.
Imperial Blue Plumbago, Lot Of Six Pots
This six-plant set is best for gardeners filling a border, larger bed, or several containers. The listing specifies six plants in 4-inch pots, with a mounding and climbing habit and mature dimensions of 3–4 feet tall by 2–3 feet wide. Bright-green foliage and sky-blue flowers are described as blooming just about all year.
Full sun supports flowering, while shade may reduce blooms. The plants prefer well-drained soil and regular watering during establishment, with additional water during drought or extreme temperatures. The listed hardiness range is zones 8–11. This larger set may be more than needed for a small patio or limited planting area.
Buying Guide: Choosing Dark Blue Plumbago
What shade of blue should you expect?
These listings use names and descriptions such as Imperial Blue, sky blue, and vivid cobalt blue. Flower color can be described differently by sellers, so treat “dark blue” as a search preference rather than a guaranteed exact shade. Check the individual listing details before ordering.
How many plants should you buy?
A single 4-inch pot suits one accent plant or container. Sets of two or three provide a small grouping, while six pots are intended for more extensive planting. Account for the listed mature spread of up to 2–3 feet when planning spacing.
Can plumbago grow in a container or on a trellis?
The potted listing identifies containers and planters as uses, and describes the shrub as trainable over a trellis. Other listings describe a sprawling or climbing habit when support is available. Choose a location with enough room for the plant’s eventual spread.
What light, water, and climate does it need?
Full sun is the most consistent recommendation, although one listing allows light shade; shade can reduce flowering. Water regularly while plants establish and more often in heat or drought. One listing gives hardiness zones 8–11, so check your local growing conditions against the product details.
