Unlocking the Secrets of Tarragon: The Herb That Won't Commit and Why I Keep Planting It Anyway

I plant French tarragon every year knowing full well what's going to happen.

Year one: gorgeous. Full, fragrant, that unmistakable anise-edged flavor that makes you understand immediately why French cuisine built an entire category around it. I harvest it, I use it, I think maybe this is the year it figures out Nebraska.

Year two: sparse. Spindly. A ghost of the plant it was. By midsummer I'm negotiating with three sad stems and wondering why I bother.

And then the following spring I buy another one anyway.

Because that flavor. There is nothing else that tastes like French tarragon. My husband makes a chicken dish with a tarragon cream sauce that is the reason I will never stop planting this herb regardless of what Nebraska winter does to it. Some plants earn unconditional loyalty. This is one of them.

Why French Tarragon Does This

Here's the part nobody tells you when you buy that cheerful little pot at the nursery:

French tarragon (Artemisia dracunculus var. sativa) doesn't produce viable seed. Every single plant you've ever bought is a clone — propagated from cuttings or division. That's already a plant living on botanical borrowed time.

In zone 5b/6a, the roots can survive a normal Nebraska winter if they're well mulched. But Nebraska doesn't do normal winters. It does warm Januaries followed by hard February freezes, and that freeze-thaw cycle is what finishes French tarragon off. The plant doesn't go sparse because you did anything wrong. It goes sparse because it's a Mediterranean herb that finds Nebraska personally offensive.

What actually helps: heavy mulch after the first hard frost, pulled back early spring before it breaks dormancy. That's what I do — every year, without fail. It doesn't guarantee survival, but it gives the plant a fighting chance against the February ambush. The south bed helps too — better heat, better drainage, which is exactly what a Mediterranean diva wants. It lives its best life there before winter gets to it.

The other honest option: buy a fresh plant every spring and treat it as an annual. French tarragon is expensive for a reason. It's high maintenance and it knows it.

Why It's Worth It Anyway

French tarragon is one of the four classic fines herbes of French cuisine — alongside chervil, chives, and parsley — and it earned that spot for a reason. The flavor comes primarily from estragole, also called methyl chavicol, which gives it that distinctive anise-adjacent sweetness that Russian tarragon completely lacks. Russian tarragon is basically flavorless. French tarragon is the one worth growing. [Confidence: High | Source: Journal of Ethnopharmacology]

That flavor is fat-soluble, which matters more than it sounds like it does. More on that in a minute.

Historical note: The name tarragon comes from the French estragon, derived from the Latin dracunculus — little dragon — likely for its serpentine roots. Medieval herbalists used it to treat snake bites, which tells you more about medieval logic than about tarragon. It never developed the herbalist reputation that mint or lavender did. It stayed in the kitchen, where it belongs. [Folklore/Historical]

What I Actually Do With It

The kitchen use is straightforward — tarragon cream sauce on chicken is the non-negotiable, and I am not apologizing for how simple that sounds because if you've had it you understand.

But here's where it gets interesting for me as a maker.

At the end of every season I do a sweep of the garden. Everything that's left — not enough dandelion for a full infusion, a handful of basil, the last of the lavender, whatever tarragon survived — gets tossed together into an oil infusion. A little bit of this, a little bit of that. The exact combination changes every year because the garden changes every year.

Tarragon goes in. Every time.

Because tarragon's constituents — estragole, ocimene, smaller amounts of sabinene — are fat-soluble. The oil actually captures something real from the plant. It's not as documented in apothecary literature as calendula or plantain. It doesn't have centuries of wound-healing folklore behind it. But it's a legitimate botanical contribution to an infused oil, and that matters to me as someone who wants to know what's actually in what she's making.

That infused oil becomes something specific. It becomes Garden Glow.

Garden Glow

Garden Glow is my end-of-season cold process soap. The oil changes every year depending on what the garden gave me. The soap changes with it. That's not a flaw in the process — that's the whole point. It's a record of that year's garden in bar form. Whatever made it to the end of the season, whatever I had just enough of to matter, goes in.

Some years there's more tarragon. Some years it's mostly dandelion and lavender. This year will be whatever the south bed and the west bed decide to give me.

Cold process is exactly right for this. The slow saponification, the full glycerin retention, the way a cold process bar holds onto botanical infusions differently than hot process — the oil I've built, layered and seasonal and unrepeatable, deserves a process that doesn't cook out what I put in.

A Note on Tarragon and Safety

Tarragon is safe in culinary use and in mild infused oils at normal concentrations — this is well established. The European Food Safety Authority has reviewed estragole and considers culinary use safe. Concentrated tarragon essential oil is a different conversation entirely, but that's not what we're making here. [Confidence: High | Source: European Medicines Agency — ema.europa.eu]

As always: patch test anything new on your skin before full use. That applies to Garden Glow the same as anything else coming out of this workshop.

I'll buy another French tarragon this spring. I already know I will. The south bed is ready, the mulch is noted for November, and I have already requested the chicken.

Some plants you grow for the harvest. Some you grow because they make you a better gardener just by being difficult. French tarragon is both.

Plant it anyway.
