Want a foreground plant that looks like nothing else? Pogostemon helferi grows tightly curled, deeply serrated leaves in a low rosette — the Thai name dao noi means "little star", which is exactly what a healthy plant looks like from above.

What You’ll Receive

Sold as loose fresh-cut plants, or potted plants:

• Bare-root Plants: Approx. 2-3 individual small plants, loose and with some root
• Potted Plants: Approx. 2-3 small plants with root potted in rockwool and net pot

Plant Profile

• Common name — Downoi, also known as Daonoi
• Scientific name — Pogostemon helferi
• Origin — Thailand
• Placement — Foreground
• Shipped size — Approx. 2-3 small plants, roughly 1-2 in
• Mature height — 2–4 in
• Suits — 10 gallons and up
• Growth rate — Slow

Care

• Difficulty — Intermediate
• Light — Medium to high. Strong light keeps the rosettes tight and low
• CO₂ — Recommended, not required
• Water — 68–78°F · pH 6.0–7.0. Prefers the cooler end
• Substrate — Required. Root and water column feeder
• Growth habit — Amphibious. Also grows emersed
• Propagation — Side shoots and runners

Grower’s Notes

• It wants cooler water than most. Downoi tops out around 78°F, noticeably lower than the 82°F most of our plants tolerate. In a warm tank it stretches, loses the tight rosette form and struggles — this is the requirement most often missed.
• Plant rosettes an inch or two apart and let them spread. Each plant throws side shoots from the base rather than growing upward.
• Expect melt on arrival. It reacts to a change of conditions by dropping leaves, then rebuilds from the center. Leave it alone for two to three weeks.
• Feed at the roots. In inert gravel the leaves come in smaller and flatter, losing the curl that makes it worth buying.
• Also available as sterile Downoi Vitro Culture, or the rare White Albino form.

Notes

• Pogostemon helferi may experience temporary melt or leaf loss when transitioning to a new environment. Ensure stable lighting, CO₂, and nutrients for successful adaptation and compact form.
• Never release aquarium plants into natural waterways.

What We Guarantee

24-Hour Live Arrival Guarantee — We guarantee that live plants and live aquatic animals will arrive alive. In the rare case of a Dead on Arrival (DOA), you must notify us within 24 hours of the delivery time recorded on the carrier's official tracking page. The guarantee is void after that 24-hour window, as condition can no longer be attributed to transit.

How to Submit a Claim

1. Take at least 2 clear, well-lit photos of the affected items in their original, unopened, sealed packaging, plus a photo of the shipping label on the box.
2. Email your photos and order number to hello@aquariumplantsfactory.com within 24 hours of delivery.
3. Do not photograph plants or animals after they have been unpacked, planted, or introduced to your aquarium — once an item enters your aquarium's ecosystem, it is no longer covered.

Approved claims are resolved with a replacement, store credit, or refund at our discretion, under the terms of our Refund Policy. Each item is eligible for one replacement only — replacements are final and we cannot replace a replacement.

Conditions That Void the Guarantee

• Incorrect or incomplete shipping address (vacant address, missing apartment number, or any issue that prevents delivery)
• Packages marked "invalid address," "undeliverable," refused, or returned to sender
• Packages left unclaimed, held at a carrier facility at the customer's request, or not retrieved promptly after delivery — live goods must be brought indoors and unpacked the day they arrive
• Carrier delays, weather events, or delivery exceptions once the package has left our facility
• Shipments to freight forwarders or package-forwarding services

Providing accurate, complete shipping information and monitoring your tracking are essential to keeping your guarantee valid.

Please note: the Live Arrival Guarantee covers arrival only. We cannot guarantee ongoing success — aquarium environment, water quality, nutrients, temperature, lighting, filtration, and CO2 all affect long-term results.

What We Can't Guarantee

1. Pest-free plants (potted & bare-root): Although our plants are grown in our own clean greenhouse, we cannot guarantee they are 100% free of snails, algae, or other hitchhikers. We recommend rinsing and quarantining all plants before adding them to your aquarium. Tissue culture (in vitro) plants are the exception — they are grown in sterile lab conditions, are 100% free of pests, algae, and disease, and have never been in contact with any aquarium.
2. Pesticide-free plants: We use homemade, organic pest control in our greenhouse and never use copper-based pesticides, which are toxic to invertebrates such as snails, crabs, and shrimp. However, we cannot guarantee plants are entirely pesticide-free — always rinse and quarantine before use in invertebrate tanks.
3. Your aquarium's success: We are not responsible for your aquarium inhabitants, including fish, shrimp, snails, and turtles. Please quarantine all plants before use.
4. Growth form: Unless specified, we do not guarantee plants will grow emersed or submersed in your particular setup.

Please review your state's regulations on restricted plants, as we are committed to not shipping plants that are restricted in your area. Do not release any plants into the wild or waterways, as this can harm local ecosystems by introducing invasive species.
