What it is
Celtuce (Stem Lettuce) (Lactuca sativa augustana) is in the Asteraceae (Daisy) family. Grown for its thick, crisp stem rather than leaves — a mild, celery-meets-lettuce crop for cool months.
How to grow it
It wants full sun to part shade, water it even, and give it rich soil. Target a soil pH around 6.0–7.0. Space plants about 8–10 in apart. Expect roughly 45–80. Cool-season.
How it's used
Celtuce (Stem Lettuce) is used: stem peeled and cooked/raw; leaves young.
🔎 How to identify it
- Tall thick edible stem
- Lettuce-like leaves up the stalk
- Milky sap

How to grow & propagate celtuce (stem lettuce)
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 celtuce (stem lettuce)
The daisy family is a seed family — those flower heads are seed factories, and most members come up fast and willing from direct sowing. The perennial members (coneflower, black-eyed Susan, the native sunflowers) also clump up over a few years and can be lifted and split in fall or early spring to make free plants and keep the center from dying out.
Growing celtuce (stem lettuce) in Texas
Give it full sun to part shade and rich soil. Match the spot to the plant and most of the battle is already won.
This is a cool-season crop. On the Texas Gulf Coast that means your real windows are fall and late winter, not summer — sow as the heat breaks in September–October and again in late winter, and you'll harvest through our mild winters while the rest of the country is frozen out.
Keep moisture even, especially while it's young — deep, less-frequent soaks build better roots than a daily sprinkle.
Harvesting
Figure on roughly 45–80 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: stem and young leaves.
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.
