Start foxnut from seed by keeping the seed moist and cold until you want it to sprout, then setting it in water around 70 F. Do not nick it.
Keep the seed moist and cold until you want it to sprout
| Factor | Recommended | Avoid |
|---|---|---|
| Store | Keep the seed moist, in a jar of water in a refrigerator around 45 F, until you want sprouts | Do not let the seed dry, and do not leave it in a warm room if you are not ready for it to grow |
| Nick | Leave the coat alone. This seed does not need the operculum lifted | Do not nick or file it the way you would a giant water lily |
| Heat | When you want sprouts, move it to room temperature or water around 70 F (about 21 C) | Do not start it in a cold outdoor pond |
| Time | Sprouts often show in a few weeks once the seed is warm and still wet | Do not toss unsprouted seed on day two |
| Move | Pot a seedling after it has real leaves, still under water, then wait for a frost-free pond | Do not drop a new sprout into a cold outdoor pond |
The seed dies if it dries. Store it wet from the day the pod opens. Cold storage around 45 F keeps it from sprouting until you are ready. [1] foxnut does not need a nick. Leave the coat intact, then warm it when you want growth. [2] Keep it moist the whole time. [3]
Can the seed dry out?
No. Keep it moist. Drying it even briefly kills the embryo.
How to start foxnut from seed
Work with a jar in a refrigerator, then a warm tank. The outdoor pond comes after the seedling has real leaves.
- Keep the seed in a jar of clean water in a refrigerator around 45 F until you want it to sprout.
- Leave the coat alone. Do not nick the operculum.
- Move the jar to room temperature, or set the seed in water around 70 F (about 21 C). Keep the water clean.
- After true leaves form, pot the seedling in heavy soil under water. The plant starts easily from seed and does not sprout on the parent. [4]
- When pads are a few inches across and frost has passed, move it into a wide pot — see Planting Foxnut.
Do I nick the seed?
No. Leave the coat intact. Giant water lily needs a nick. This seed does not.
What fails when you sow
A dry seed is dead. Nicking the coat can hit the embryo on a seed that does not need it. Warm storage when you wanted dormancy makes it sprout in the jar. After the seedling has real leaves, a wide pot and a frost-free pond are the next jobs — not a second nick.
If the seed dries, it will not sprout. Keep the next batch wet, and cold until you want it to grow.
FAQ
Will it bloom the first year?
Often yes in a long, hot season, because the plant grows from a pea-sized seed to blooming size in months. A late start in a cool pond may only make pads.
Can I save seed from the pond for next year?
Yes. Collect ripe seed, keep it moist and cold, and start it again in spring. That is seed-saving, not a popping recipe.
