What it is
Tomatillo (Physalis philadelphica) is in the Solanaceae (Nightshade) family. The tart green husk-fruit behind salsa verde. Needs two plants to set fruit, and loves Texas heat.
How to grow it
It wants full sun, water it moderate, and give it average soil. Target a soil pH around 6.0–7.0. Space plants about 24–36 in apart. Expect roughly 75–100. Warm-season annual.
How it's used
Tomatillo is used: salsa, roasted, sauces.
🔎 How to identify it
- Sprawling branching plant
- Papery lantern husk
- Green-to-purple fruit inside

How to grow & propagate tomatillo
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 tomatillo
Tomatoes, peppers, eggplant and their cousins are warm-season crops started inside 6–8 weeks before your last frost, then transplanted out once nights stay above 50°F. Tomatoes are the exception to most rules — you can bury the stem deep or root a side shoot (a 'sucker') in water to clone a plant mid-season. Potatoes skip seed entirely and grow from seed potatoes — chunks of tuber with an eye or two.
Growing tomatillo in Texas
Give it full sun and average 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.
Keep moisture even, especially while it's young — deep, less-frequent soaks build better roots than a daily sprinkle.
Harvesting
Figure on roughly 75–100 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: fruit (husk removed).
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.
