What it is
Yarrow (Achillea millefolium) is in the Asteraceae (Aster) family. An ancient first-aid herb and pollinator magnet that spreads by runners and divides endlessly — tough as any Texas native.
How to grow it
It wants full sun, water it low — very drought-tough, and give it lean, well-drained soil. Target a soil pH around 5.5–8.0. Space plants about 12–18 in apart. Expect roughly Blooms first summer from spring sow. Hardy perennial.
How it's used
Yarrow is used: leaves and flowers (traditional medicinal).
🔎 How to identify it
- Feathery, fern-like soft leaves
- Flat clusters of tiny white flowers
- Aromatic when crushed

How to grow & propagate yarrow
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 yarrow
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 yarrow in Texas
Give it full sun and lean, well-drained 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.
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 blooms first summer from spring sow before you're harvesting. Pick herbs in the morning after the dew dries for the strongest oils, and harvest little and often — regular cutting keeps a herb bushy and stops it bolting. The part you're after: leaves, flowers — medicinal use.
Making more for free
If you want more, let your healthiest plants mature fully and collect the seed once it's dry on the plant — then store it somewhere cool, dark, and dry until next season.
Keep this knowledge offline
A garden full of yarrow 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.
