Wildflower.org Native Plant Database Scraper

Scrapes the Lady Bird Johnson Wildflower Center NPIN (Native Plant Information Network) — the canonical US native-plant database with ~9,000 species. Returns scientific name, common names, USDA symbol, growing conditions, bloom data, wildlife value, pollinator and butterfly larval-host data, and commercial availability.

What does it scrape?

• Source: wildflower.org/plants — the authoritative North American native plant reference maintained by the Lady Bird Johnson Wildflower Center at UT Austin
• Coverage: ~9,000 native plant species (all plant families)
• Data per plant: ~30 fields covering taxonomy, growing conditions, ecology, and horticultural use

Use Cases

• Building native plant recommendation tools and apps
• Ecological research and biodiversity analysis
• Horticultural and landscaping databases
• Pollinator habitat and butterfly larval host mapping
• Retail nursery and seed catalog enrichment

Notes

• The scraper discovers all plant families automatically from the NPIN search index, then collects plant IDs from each family listing, and finally fetches each plant's detail page.
• Use the families input to limit coverage to specific botanical families (faster runs for targeted research).
• maxItems: 0 returns all available plants — expect a full run to take several hours for the complete ~9,000 plant dataset.
• Residential proxy is required to access the site reliably.
