Rhode Island Xeriscaping Guide
Published: June 6, 2026 · Updated:
Drought-tolerant landscaping plans for 1 Rhode Island cities across USDA zones 5b. Find native plants, water-saving strategies, and xeriscape designs for your specific location.
Water Restriction Level: low
Water conservation is becoming increasingly important across the US as drought patterns shift. Xeriscaping reduces outdoor water use by 50–75%.
What drives landscape water use in Rhode Island
Humid coastal with sandy soils and salt exposure that favour tough, unirrigated plantings.
Mean annual precipitation across Rhode Island spans about 44 to 52 inches, and the state covers USDA hardiness zones 5b. That spread matters more than any single statewide number: the wettest and driest parts of Rhode Island need different plant palettes and different irrigation entirely, which is why the zone for your own city is the figure to plan against rather than a state average.
Plant genera native to Rhode Island
These genera are native to Rhode Island and are the backbone of low-water planting here. Starting from natives matters because they evolved with the local rainfall pattern and soil, so once established they generally need no irrigation beyond what the climate provides.
Listed at genus level deliberately. Which species within a genus is native varies across Rhode Island, so check the species with a local native plant society or extension office before buying.

Turf removal rebates in Rhode Island
We have not verified a residential turf removal rebate at any Rhode Island water provider. Programs of this kind are concentrated in the arid south west, where utilities pay per square foot to cut peak summer demand. Some Rhode Island utilities do offer irrigation-equipment or fixture rebates instead, which are worth asking about, but they are not the same thing as being paid to remove grass. Check with your own provider rather than assuming, and see our turf removal rebate comparison for the cities that do pay.
Xeriscaping Principles for Rhode Island
1. Plan and Design
Start with a water-efficient landscape plan that groups plants by water needs. Place high-water plants (if any) closest to the house and low-water plants further away.
2. Improve Soil
Amend soil with compost to improve water retention in sandy soils and drainage in clay soils. Healthy soil holds more moisture and supports deeper root systems.
3. Reduce Turf Area
Limit conventional lawn to areas that serve a functional purpose (play areas, pathways). Replace decorative turf with native plants, ground covers, or mulch.
4. Choose Low-Water Plants
Select native and adapted plants suited to your USDA zone. Native plants have evolved with local rainfall patterns and typically need no supplemental irrigation once established.
5. Mulch Generously
Apply 5–10cm of organic mulch (or gravel in desert climates) around all plantings. Mulch reduces evaporation by up to 70%, suppresses weeds, and moderates soil temperature.
6. Irrigate Efficiently
If irrigation is needed, use drip systems or soaker hoses rather than sprinklers. Water deeply and infrequently to encourage deep root growth. Water before 9am to reduce evaporation.
7. Maintain Appropriately
Proper maintenance reduces water waste. Keep mulch refreshed, prune to reduce water demand, and adjust irrigation seasonally. A well-maintained xeriscape improves over time.
Rhode Island cities and their USDA zones
Your hardiness zone is the single most useful number for choosing plants, so this is every Rhode Island city we hold, with its zone. Cities shown as links have their own guide because they run a verified turf rebate worth explaining on its own page. For the rest, the zone below plus the state palette above is the plan: their local advice would not differ from what is on this page.
