Popular Landscaping Styles
Discover design styles perfectly suited to Arkansas's unique climate and landscape
Naturalistic design inspired by the mixed hardwood forests of the Ozark and Ouachita highlands — using native wildflowers, ferns, and understory trees on rocky, acidic hillside soils
Key Features:
- •Eastern redbud and flowering dogwood as early-spring canopy layers
- •Wild blue phlox (Phlox divaricata) and trillium as woodland floor plants
- •Arkansas bluestar (Amsonia hubrichtii) for steel-blue spring flowers and gold fall foliage
- •Native limestone or sandstone retaining walls matching local geology
Informal, layered Southern style suited to the flat alluvial lands of eastern and southern Arkansas — abundant blooms, shade trees, and productive kitchen gardens
Key Features:
- •Crepe myrtles as multi-stem summer flowering trees
- •Daylily and coneflower borders along fences and walkways
- •Southern magnolia or live oak for long-term canopy shade
- •Raised vegetable beds in composted Delta soil
Prairie-influenced design using Arkansas native wildflowers and grasses — particularly effective in the transition zone between Ozarks and Delta where both highland and lowland species thrive
Key Features:
- •Arkansas bluestar, purple coneflower, and black-eyed Susan for sequential bloom
- •Little bluestem and sideoats grama as native grass structure
- •Mowed edge paths to keep the design looking intentional, not unkempt
- •Brush pile or log stack as wildlife habitat feature
Practical, year-round design emphasizing drought-tolerant natives and adapted plants that need minimal care once established — ideal for Arkansas homeowners with limited time
Key Features:
- •Loropetalum and native azaleas for low-maintenance spring color
- •Liriope muscari as no-mow border edging
- •Native sweetshrub (Calycanthus floridus) for fragrant understory
- •Mulched beds reducing mowing and weed pressure
Recommended Plant Palettes
Native and adapted plants that thrive in Arkansas's climate
Eastern Redbud
Cercis canadensis
Covered in magenta-pink flowers in late March before leaves emerge; one of the most reliable native spring-blooming trees across all Arkansas zones — tolerates clay, sandy loam, and rocky Ozark soils
Arkansas Bluestar
Amsonia hubrichtii
Arkansas native endemic to the Ouachita Mountains; steel-blue star flowers in spring, fine-textured summer foliage, brilliant golden fall color — a four-season plant that requires zero care once established
Purple Coneflower
Echinacea purpurea
Pink-purple daisy flowers June–August attract bees and goldfinches; drought-tolerant prairie native that thrives in Arkansas clay and adapts to rocky Ozark soils with no supplemental watering
American Beautyberry
Callicarpa americana
Arching shrub with electric-magenta berries in September–October; native to Arkansas woodlands, tolerates part shade and clay soil, and provides critical late-season food for 40+ bird species
Crepe Myrtle
Lagerstroemia indica
Summer-blooming tree or large shrub with flowers June–September in white, pink, red, or purple; tolerates Arkansas heat and humidity and provides attractive exfoliating bark through winter
Native Azalea
Rhododendron canescens
Fragrant pink flowers in April before leaves emerge; native to Ozark and Ouachita highlands and far more durable than imported Asian azaleas in Arkansas soils and summer heat
Turk's Cap
Malvaviscus arboreus
Red pinwheel flowers from June through frost attract hummingbirds; thrives in shade or sun with summer heat and humidity that defeats most perennials
Swamp Milkweed
Asclepias incarnata
Pink flowers June–August are monarch butterfly host and nectar source; tolerates the wet clay and seasonal flooding common in Delta and river-bottom Arkansas landscapes
Wild Blue Phlox
Phlox divaricata
Native woodland groundcover producing fragrant lavender-blue flowers in April–May under the deciduous canopy; spreads gently to fill shaded areas in Ozark-style gardens
Sweetshrub
Calycanthus floridus
Rounded native shrub with unusual burgundy-brown flowers with a strawberry-spice fragrance in May; adapts to part shade and clay — a Southern heirloom plant native to Arkansas
Autumn Fern
Dryopteris erythrosora
New fronds emerge coppery-orange before maturing to deep green; one of the most adaptable ferns for Arkansas shade gardens — semi-evergreen and tolerates summer heat
Green-and-Gold
Chrysogonum virginianum
Native groundcover with bright yellow flowers spring through fall in dappled shade; spreads to suppress weeds under trees and requires no supplemental watering after establishment
Seasonal Garden Checklist
Your year-round guide to maintaining a beautiful Arkansas garden
Plant spring bulbs (tulips, daffodils, alliums) before ground freezes
Prune dormant trees, fruit trees, and summer-blooming shrubs
Plant cool-season vegetables: broccoli, cabbage, lettuce, carrots, peas
