Lobelia Cardinalis: What's a Fair Price?

Lobelia Cardinalis is sold in 5 different forms (tissue-culture cup, potted, bare root / rhizome, stem bundle, form not stated) across 4 US vendors — 12 listings tracked, 9 in stock, updated September 4, 2026. Prices below are grouped by form because a tissue-culture cup, a mature pot and a bundle are different products; comparing them against each other would be misleading.
