Tephro is a market and collection platform for people interested in cacti and euphorbias, from familiar nursery plants to rare specimens that collectors may have searched years to find. Presented as a rare cactus market terminal, it helps users explore active listings and follow prices, with fair-range information to provide context when assessing the market. The platform also surfaces source trust and provenance context, supporting more informed consideration of where plants come from and how listings should be evaluated.

For collectors managing plants as well as browsing for new additions, Tephro offers private collection tools. Its coverage spans a broad range of cactus and euphorbia varieties, bringing market discovery and personal collection management together in one place. Tephro identifies GBIF and LLIFLE as taxonomy sources, reflecting the reference information used in its plant-focused experience.
