Pennywort — Hydrocotyle verticillata
The coin-leaf plant that works beautifully above and below the waterline
Pennywort is one of the most distinctive aquatic plants available — its perfectly round, coin-shaped leaves make it an instant focal point in any aquascape. Unlike most stem plants, it grows equally well fully submerged or emergent above the water surface, making it a rare dual-purpose plant that fits tanks, terrariums, and indoor water gardens alike. Spreads naturally through runners for effortless, organic coverage.
Aquascaping tip: Let runners spread naturally along the substrate for a low carpet effect in the foreground, or allow stems to grow toward the surface for a mid-ground accent. Works beautifully alongside fine-leafed plants like foxtail or hornwort for contrast.

Two ways to grow
1. Fully submerged in aquariums
2. Emergent in terrariums or pond setups
Most aquatic plants are strictly one or the other. Pennywort thrives in both — use it in a planted tank as a foreground or midground accent, or let it grow above the waterline in a paludarium, indoor water garden, or outdoor tub pond. The same bundle works for either setup.

Customer questions answered
(Q) Do I need CO₂ injection to grow this successfully?
= CO₂ is optional, not required. Pennywort grows at a medium pace without it under medium to high lighting. Adding CO₂ will accelerate growth and keep leaves a brighter, richer green — but most hobbyists grow it successfully in standard low-tech setups. A weekly liquid fertilizer is the more impactful upgrade if you want to improve results without CO₂ equipment.
(Q) Can I really grow this outside the water, and how does that work?
= Yes — Pennywort is a true amphibious plant. When grown emergent (above the waterline), it produces slightly larger, more upright leaves and often grows more vigorously than when fully submerged. You can place it in a paludarium, a shallow water dish, or an outdoor pond or tub garden with its roots wet. It's the same plant shipped to you — no special emergent variety needed.
(Q) How does it spread, and will it take over my tank?
= Pennywort spreads through horizontal runners along the substrate — new plantlets emerge naturally a few inches from the parent stem. Growth is medium-paced, so it fills in gradually rather than explosively. You can let runners spread freely for a natural carpet effect, or trim and redirect them to keep it contained. It will not aggressively crowd out neighboring plants the way fast stem plants sometimes do.
What's included: 1 bundle of Pennywort (Hydrocotyle verticillata), 1–4 inches, ready to plant in substrate or place in an emergent setup upon arrival.

Great addition!
Size: 40 Inch, Color: Rustic Brown, Number of Items: 1
Floating shelf was super easy to install and is a great addition above my window in my office. I used it to put some display pieces my wife wouldn’t allow me to put over our mantle. Very sturdy and looks great!

Looks Good-Not at all sturdy
Size: 40 Inch, Color: Rustic Brown, Number of Items: 1
Looks good. Not sturdy at all if you want to put any weight on it. It’s purely decorative and is not a functional shelf. I had to use toggle bolts for a hollow wall install. The hardware included was not helpful.

Poor quality product, hardware not appropriate
Size: 24 Inch, Color: Black, Number of Items: 1, Size: 24 Inch, Color: Black, Number of Items: 1
Do not waste your money on these, not as described, very cheap, hardware does not work. Going to have to repair my wall before I can do anything else. Completely unacceptable product. Very frustrating and was not properly represented in the marketing advertising. Do not buy. Would like to return, but waited 3 days to long. If I had opened them immediately I would have seen the poor quality.
