What it is
Chaya (Tree Spinach) (Cnidoscolus aconitifolius) is in the Euphorbiaceae (Spurge) family. A Maya superfood shrub that pumps out nutritious greens through the worst heat, roots from a stick, and outlives nearly everything.
How to grow it
It wants full sun to part shade, water it low — drought-tough, and give it adaptable soil. Target a soil pH around 6.0–7.5. Space plants about 6 ft apart. Expect roughly Leaves year-round once established. Tender perennial (root-hardy).
How it's used
Chaya (Tree Spinach) is used: cooked leaves only.
🔎 How to identify it
- Large maple-like lobed leaves
- Milky sap when cut
- Woody shrub, grows from cuttings

How to grow & propagate chaya (tree spinach)
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 chaya (tree spinach)
Chaya (Tree Spinach) comes up from seed and, once it's a few years old, can be lifted and divided in cool weather to make more plants and keep the clump vigorous.
Growing chaya (tree spinach) in Texas
Give it full sun to part shade and adaptable soil. Match the spot to the plant and most of the battle is already won.
This one thrives in heat that flattens other plants, so it earns its space through a Texas summer. Get it established before the worst of July, keep water steady, and it'll produce when little else will.
Once it's rooted in, this is a low-water plant — overwatering does more harm than drought here. Water deeply to establish, then back off and let it prove how tough it is.
Harvesting
Figure on roughly leaves year-round once established 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: leaves — must be cooked.
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 chaya (tree spinach) 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.
