Stokes' aster (Stokesia laevis 'Peach Melba')

Overview

Stokesia laevis ‘Peach Melba’ introduces stunning, unusually colored fringed blooms to the summer garden. This cultivar of Stokes’ aster stands out with its fluffy, cornflower-like flowers featuring creamy white rays contrasted by a delicate pastel peach center, providing excellent visual appeal where many traditional summer bloomers fade. As an evergreen perennial in warmer regions, it offers consistent texture in the landscape, making it highly valuable for reliable summer color.

This herbaceous perennial typically reaches a manageable height of 1 to 1.5 feet, thriving in sunny locations. Gardeners appreciate Stokesia laevis ‘Peach Melba’ for its relatively low maintenance requirements combined with surprising resilience against mild drought conditions once established. It demands well-drained conditions above all else, as wet winter soil is its main threat.

The compact yet substantial flower heads make this selection of Stokes’ aster perfect for adding cheerful, soft tones to cottage or mixed perennial borders. Utilizing Stokesia laevis ‘Peach Melba’ ensures you have reliable late-season interest without constant fuss, provided morning sun and good drainage are assured.

How to Grow

Planting Stokes’ aster should occur when the threat of hard frost has passed, ensuring it settles well before summer heat arrives. The absolute primary requirement for success is excellent soil drainage; avoid heavy clay unless heavily amended. While adaptable to average soil, this variety prefers moist, sandy compositions. Placing it in full sun guarantees the best flower production, although filtered light is tolerated.

Ongoing care for Stokesia laevis ‘Peach Melba’ centers on moisture management. Provide consistent, medium water, especially during dry spells, but never let the plant sit in soggy soil, particularly over winter. Fertilizing is rarely necessary; overly rich soil can encourage flopping stems rather than robust flowers.

To maximize the season of color from your Stokesia laevis ‘Peach Melba’, deadhead spent individual flowers promptly. Removing spent flowering stems encourages repeat blooming throughout the summer and into early fall. In colder areas (Zone 5), applying a layer of winter mulch protects the basal foliage. After the main bloom concludes, plants can be neatly cut back to the basal rosette for tidiness.

Landscape Uses

The refined size and vibrant late-season color of Stokesia laevis ‘Peach Melba’ make it an outstanding choice for border fronts, providing excellent mid-story structure. Their requirement for moist areas means they integrate beautifully near the edges of ponds, streams, or established water gardens where soil moisture remains consistent. For cottage gardens, mass plantings create a soft, cloud-like drift of peach-toned blooms.

Consider grouping Stokes’ aster with plants that share similar sun and moisture needs but contrast in texture or height, such as ornamental grasses or lower-growing, deep purple salvias. Due to their height (1 to 1.5 feet), they work well in small groupings to draw the eye without obscuring shorter border companions placed in front of them.

Noteworthy Characteristics

Stokesia laevis, commonly known as Stokes’ aster, is native to wetlands, bottomlands, wet pinewoods, savannas and ditches mostly along the coastal plain from North Carolina to Florida to Louisiana. It is an evergreen perennial that typically grows to 1-2’ tall. It features fluffy, cornflower-like, violet blue flowers (to 2 1/2” across), each with notched rays surrounding a pincushion center of feathery disk florets. Flowers bloom from early to mid-summer (sometimes with a fall rebloom) atop generally erect, leafy stems that rise from a basal rosette of lanceolate to elliptic, medium green leaves (to 6” long). Stem leaves are stalkless and smaller than basal leaves. Leaves are evergreen in warm winter climates.Genus name honors English physician/botanist Jonathan Stokes (1755-1831).Specific epithet means smooth.‘Peach Melba’ features fluffy, cornflower-like flowers (to 3” across) with creamy white outer rays and pastel peach centers on generally erect, leafy stems growing to 12-18” tall.

Potential Problems

This plant generally experiences no serious insect or disease problems, which contributes to its low maintenance rating. Gardeners should occasionally watch for caterpillars that might feast on the foliage or flowers. The most common physical challenge for Stokesia laevis ‘Peach Melba’ involves stem strength; flower stems can sometimes flop, especially after heavy Midwestern rain or thunderstorms, although this cultivar is noted to be more structurally sound than some other Stokes’ aster varieties. Good air circulation and proper spacing help mitigate most issues.

Conclusion

Stokesia laevis ‘Peach Melba’ offers significant architectural and color value, successfully blending unique peach tones with the reliable constitution of an evergreen perennial. Its low maintenance needs, combined with drought tolerance and rabbit resistance, make this iteration of Stokes’ aster indispensable for sunny, well-drained borders. Before planting, always confirm your site drainage is adequate, as this is the single most important factor for long-term success.

Companion Planting

When selecting companions for Stokes’ aster, prioritize plants that also enjoy full sun and thrive in average to moist, but importantly, well-drained soils. Good companions include ornamental grasses like Sporobolus or Panicum, which offer contrasting vertical textures without competing heavily for nutrients. Lavender or Russian Sage can provide aromatic contrast while tolerating the plant’s preference for dry conditions once established, balancing the medium water needs during peak summer heat.

Design Ideas

Utilize the uniform height of Stokesia laevis ‘Peach Melba’ to anchor the middle layer of a mixed border. Place it opposite plants with deeper, cooler colors, such as deep blue Amsonia or dark purple Geraniums, to make the warm peach centers truly pop under the summer sun. For a cottage effect, intersperse them with silvery foliage plants like Lamb’s Ears (Stachys byzantina) or taller spire-like flowers such as Veronica for vertical variation.
