What it is
Chufa (Tiger Nut) (Cyperus esculentus var. sativus) is in the Cyperaceae (Sedge) family. A grass-like sedge that makes sweet, nutty underground tubers — the original ingredient in horchata, and a calorie crop that stores dry for years.
How to grow it
It wants full sun, water it moderate to high, and give it loose, sandy soil. Target a soil pH around 5.5–7.5. Space plants about 6 in apart. Expect roughly 90–120 to tubers. Tender perennial (grown as annual).
How it's used
Chufa (Tiger Nut) is used: tubers raw, dried, milk (horchata).
🔎 How to identify it
- Triangular grass-like stems (sedge)
- Clumps of slender leaves
- Small sweet tubers on the roots

How to grow & propagate chufa (tiger nut)
Everything I've worked out about starting this one, keeping it alive through a Texas year, and turning one plant into many — free.
How to propagate chufa (tiger nut)
Chufa grows from its own little tubers — plant a few an inch deep in warm, loose soil and each one multiplies into a clump that makes dozens more by fall. Save some of the harvest to replant. Because it spreads, many growers keep it in a tub or bed they can contain.
Growing chufa (tiger nut) in Texas
Give it full sun and loose, sandy soil. Match the spot to the plant and most of the battle is already won.
Because it's a perennial, the work is mostly up front. Get it sited and established and it comes back on its own year after year — one of the best returns on effort in the whole garden.
Keep moisture even, especially while it's young — deep, less-frequent soaks build better roots than a daily sprinkle.
Harvesting
Figure on roughly 90–120 to tubers before you're harvesting. Harvest at peak and keep harvesting — most vegetables produce harder the more you pick, and one left to over-mature tells the plant its job is done. The part you're after: tubers.
Making more for free
Every seed we sell is open-pollinated, which means you can save your own from the best plants and it'll grow true next year. Let a few of your strongest plants finish and go to seed, dry it fully, and store it cool and dark. That's the whole point of heirlooms — buy once, grow forever.
Keep this knowledge offline
A garden full of chufa (tiger nut) is a real asset when times get hard — but the know-how to grow, store, and use it shouldn't live only on a website you can't reach. That's why I keep a copy of the references I rely on on a local server at home. Project NOMAD is a free, open-source way to run Wikipedia, survival and medical guides, maps, and even a private AI on your own hardware — knowledge that keeps working with no internet, no cloud, no signal.
