Water Poppy

Water Poppy (Hydrocleys nymphoides) is an aquatic plant native to pond ecosystems. Used in ornamental pond design for visual interest, biological filtration, and providing cover.

Water Poppy requires a minimum of 50 gallons (pond) for healthy adults. The minimum is based on 12 inch spread adult size and territorial range. Plan an outdoor pond with appropriate depth (3+ feet for cold-climate winterization), filtration sized 1.5-2x pond volume per hour, UV clarifier, and surface skimmer.

Water Poppy prefers pond parameters: temperature 50-78°F seasonal swing for cold-tolerant species, pH 7.0-8.5, ammonia + nitrite 0 ppm, nitrate under 40 ppm, dissolved oxygen 5+ mg/L (aerator non-optional in summer).

Water Poppy is a photosynthetic. Powered by photosynthesis. Maintain quality lighting matched to species needs. Browse our food guides for product recommendations.

Water Poppy is compatible with similar-temperament pond fish at appropriate stocking. Plan stocking around adult sizes and territorial behaviors.

Water Poppy reaches 12 inch spread at adulthood with a captive lifespan of perennial years with proper care.

Water Poppy propagates through tubers, runners, or division. Most aquatic plants propagate freely once established.

Water Poppy can develop pond-specific issues: parasites, bacterial infections, and seasonal stress around water temperature transitions.
