Hardiness Zone 11. Flag: this is a true floating aquatic plant (per the source listing's own "Use: Floating"), not a terrestrial terrarium plant — likely miscategorized under Terrarium Plants, similar to Azolla Caroliniana found earlier in this pass. Recommend recategorizing to Aquarium Plants (Floating). |
Care & Planting: Neptunia aquatica, the sensitive plant, has fern-like foliage that visibly contracts when touched — a fun interactive floater for aquariums or outdoor ponds. It produces small, bright yellow, 1-inch flowers and grows 3-5" tall as a floating mat. Provide bright light and stable water temperatures; no substrate or planting is needed since it floats freely at the surface.
