Every fact tells you where it came from

Each name, range and record carries its source, its licence and a link back to the original. A botanist should never have to take our word for it.

Herbarium records with their full history Coming soon

Specimen records from Louisiana herbaria, with every determination on the sheet, newest annotation first. The current name leads; the earlier names stay for anyone tracing how a plant was understood.

Names through time

More than 32,000 plants checked against Kew's world plant list, with old names linked to current ones. Coming soon: historical names from old Gulf South nursery catalogs, showing what was grown and sold, and under what name.

Plants and wildlife, connected

Which insects, birds and other animals use each plant, drawn from museum collections, field observers and published studies, with every record's source shown.

Ranges and maps

Where each plant has been recorded, from herbarium sheets and observations, starting with the Southeast and growing.
