Nymphaea August Koch | Aquarium Plants Factory®

A 1922 introduction that propagates itself. Nymphaea 'August Koch' carries large, fragrant violet-blue flowers over olive-green pads, and it is highly viviparous — new plantlets form on the leaves, so one plant becomes several. It was raised at Garfield Park in Chicago and named for August Koch, who bred it alongside George H. Pring.

Grower's Notes

• Highly viviparous, which is the practical reason to choose it. Plantlets form on mature pads and can be lifted and potted once they have roots and a leaf of their own. Most lilies only increase by division — this one multiplies through the season on its own.
• Over a century in cultivation. A 1922 cultivar that is still sold has earned its place on performance, not novelty.
• Fragrant as well as blue. Scent is not a given among the blue tropicals, so site it where people sit.
• Wants still water and real warmth — 70–80°F suits it. Keep the pot clear of fountains and waterfall outflows.
• Leave old pads in place while plantlets are forming. Tidying them away removes the next generation.

Notes

• We don't ship dormant roots. Your tuber arrives fresh and actively growing with 1–2 young leaves already emerged — visible proof it's viable before it leaves us. Young pads may start fully submerged and will reach the surface within about a week in good light.
• Remove dead leaves and spent flowers to keep the water clean — though leave any pad carrying plantlets until they are ready to lift.
• Never release aquatic plants into natural waterways.
