Soil texture, pH range, moisture use, wet-soil (anaerobic) and drought tolerance: USDA NRCS PLANTS Database characteristics (retrieved 2026-10-14); “sand/loam/clay” = adapted to coarse/medium/fine-textured soils. Rain-garden tag: listed in VCE Rain Garden Plants (Virginia; genus-level entries count).
Your soil, water and flood risk
- Soil type: look up your yard in the official USDA NRCS Web Soil Survey (texture, drainage class, flooding/ponding frequency).
- Flood zone: check the official FEMA Flood Map Service Center.
- Soil test: before amending, get a lab soil test through your state Extension (e.g. Virginia Cooperative Extension Gardener Handbook, ch. 2: sample 10+ spots to 6 inches; test every 3–4 years).
- Raised beds / amendments: University of Maryland Extension recommends filling raised beds with compost and topsoil at 1:2 or 1:1 (or compost and soilless mix 1:1) and a pH of 6.2–6.8 for most garden plants (UMD: Soil to Fill Raised Beds). Extension guidance warns against adding sand alone to clay; work in organic matter instead.
Rainfall: Illinois averaged 40.7 inches of precipitation per year, 1991–2020 (mean of annual statewide totals, NOAA NCEI Climate at a Glance). See wet yard & rain garden guide.
Nativity: USDA NRCS PLANTS state distribution (retrieved 2026-10-14); "native to the state" does not mean native to every county or habitat. Hardiness, light and size: NC State Extension Gardener Plant Toolbox where linked, otherwise our unverified estimate. Check your site, ZIP zone and local nursery stock; ask your county Extension office or state native plant society.
