How to Grow Hawaiian Native Ground Covers
Hawaiian Native Ground Covers
Various species (Portulaca sclerocarpa, Lysichiton americanus subsp. kamchatcensis, Ipomoea pes-caprae, etc.)
groundcoverHawaiian native ground covers are a diverse group of low-growing plants adapted to the islands' tropical and subtropical climates, volcanic soils, and varied precipitation patterns. These plants provide ecological benefits, erosion control, and cultural significance while requiring minimal maintenance once established. They include succulent species, vining plants, and herbaceous covers suited to different elevations and moisture conditions.

Establishment
4-8 weeksYoung plants are establishing root systems and beginning lateral growth; foliage is sparse and tender
Water regularly to keep soil consistently moist (not waterlogged) for 4-6 weeks. Protect from strong winds and excessive direct sun if possible. Apply light mulch around plants.
Vegetative Growth
8-16 weeksPlants develop fuller foliage, runners, or spreading stems; coverage begins to expand across the planting area
Reduce watering frequency as drought tolerance increases. Remove weeds competing for space. Light fertilization with balanced or low-nitrogen fertilizer if needed. Prune to encourage branching.
Spreading/Maturation
12-24 weeksPlants actively spread via runners, creeping stems, or self-seeding; coverage becomes denser and more uniform
Minimal water needed except during extended dry periods. Redirect runners to fill gaps. Deadhead flowers if reducing self-seeding is desired. Reduce fertilizer applications.
Full Coverage
Ongoing maintenance phaseGround cover forms a dense mat or canopy suppressing weeds and stabilizing soil; flowering may occur seasonally
Water only during drought. Occasional light pruning or mowing to maintain neatness. Remove debris from canopy. Monitor for pests and disease.

and
Handpick in early morning; use copper barriers or diatomaceous earth; encourage native predators like birds
-
Spray with water to dislodge; apply neem oil or insecticidal soap; encourage natural predators
-
Handpick or prune affected areas; apply horticultural oil or insecticidal soap; maintain plant vigor

Uses
Erosion Control & Slope Stabilization
EcologicalNative ground covers with dense root systems stabilize volcanic slopes and prevent soil erosion on hillsides, particularly important in Hawaii's steep terrain. Their establishment reduces runoff and sedimentation into streams and coastal waters. [source]
Native Habitat Restoration
EcologicalUsing Hawaiian native ground covers in restoration projects helps recreate historical plant communities, support endemic insects and birds, and maintain genetic diversity of island species. This supports conservation of Hawaii's unique biodiversity. [source]
Low-Maintenance Landscaping
HouseholdOnce established, native ground covers require minimal water, fertilizer, and maintenance compared to non-native lawn grasses, making them ideal for dry climates and xeriscaping. They reduce landscape maintenance costs and water consumption. [source]
Traditional Hawaiian Foods
CulinarySome species like Ohelo (Vaccinium reticulatum) produce edible berries used in traditional Hawaiian cuisine and by native peoples for thousands of years. These foods carry cultural and nutritional significance. [source]
Cultural & Spiritual Significance
CulturalMany Hawaiian native plants hold deep cultural meanings in Hawaiian tradition, hula, and spiritual practices. Growing native ground covers supports cultural continuity and connection to Hawaii's natural heritage. [source]
Harvest Tips
Most Hawaiian native ground covers are grown for foliage and ecological value rather than harvest. Some species produce edible berries (Ohelo) that can be hand-picked when ripe. For propagation, collect seeds in dry season or take stem cuttings 4-6 inches long in spring. Trim and deadhead flowering stems to encourage bushiness and prevent unwanted self-seeding.
Fun Facts
- 🌱 Hawaii has over 1,000 native plant species, with about 90% found nowhere else on Earth—these endemic plants evolved in isolation over millions of years and many are now threatened or endangered.
- 🌱 Many Hawaiian native ground covers are found only at specific elevations or microclimates, from sea-level coastal strand vegetation to high-altitude alpine shrublands, reflecting the islands' diverse ecosystems.
- 🌱 Native Hawaiian ground covers often have special adaptations to the islands' volcanic landscape, including salt tolerance for coastal areas, drought resistance for leeward slopes, and shade tolerance for wet windward forests.
