- Native vs. invasive status by region
Growing Conditions
- Hardiness zones (min/max)
- Drought tolerance, heat tolerance
- Soil requirements, light needs
Physical Characteristics
- Plant habit (tree, shrub, etc.)
- Flower colors, bloom months
- Leaf & fruit characteristics
Ethnobotany & Uses
- Edible parts & preparation
- Medicinal & economic uses
- Wildlife attractants
Conservation Status
- Global conservation rank
- Rarity classification

County-Level Precision Changes Everything
Most plant databases give you state-level data. Flora gives you county-level — because ecology doesn't follow state lines.
Conservation Planning
Identify which species are actually present in a specific county before recommending them for restoration.
Invasive Species Management
Know exactly which counties an invasive species has reached, not just which states.
App Development
Build tools that give users locally accurate results — "plants in your county" instead of "plants in your state."
State-Level
"Present in California"
County-Level
"Present in Marin, Sonoma..."

Built on Public Domain Data, Verified at Scale
Flora's core dataset is built from the USDA PLANTS Database (public domain), covering every vascular plant species documented in the United States. County-level distribution data covers all lower 48 states with Alaska and territories being added incrementally. Species images are sourced from USDA, Wikimedia Commons, and iNaturalist under appropriate licenses.
