Barberries and the Lessons of Place
As a bioregional herbalist, I believe in honoring the plants of place—the ones that grow right outside our door, whether native or invasive. To me, even plants that crowd out others or shift ecosystems have lessons to share. Barberry is one such plant.
Here in the Northeast, two kinds are especially common: Common barberry (Berberis vulgaris) and Japanese barberry (Berberis thunbergii). Both have spread far beyond gardens and hedgerows, filling forest edges and stone wall borders. While their invasiveness poses challenges, they also hold a long lineage of traditional use.
The Invasiveness of Barberries
Barberry made its way here as a garden favorite. Common barberry was planted centuries ago as a practical hedgerow, while Japanese barberry became popular later for its neat, compact shape, colorful foliage and striking red berries.
When I purchased my first home back in the early ’90s, long before I had begun studying native plants and invasives, I actually bought a few barberry shrubs myself. I admired their lovely red foliage and the bright clusters of berries that glowed against the autumn leaves. I still think they’re pretty in their own way, but with the knowledge I carry now, I would never knowingly plant them again (and I have since removed those I did plant).
What began as an admired ornamental has since slipped beyond gardens, spreading aggressively through woodlands, roadsides, and forest edges all across the Northeast. Still, my early experience reminds me how easy it is to fall for their beauty, and how important it is to keep learning and adapting with the land.
Why they’re considered invasive:
-
Barberries form dense thickets, shading out native plants.
-
Ticks & Lyme disease: Studies suggest barberry thickets create a humid understory that favors deer ticks, increasing the risk of Lyme disease.
-
Common barberry can act as an alternate host for black stem rust (Puccinia graminis), a fungal disease harmful to wheat crops.
-
Barberry thickets can alter local ecology, creating conditions that shift insect and animal populations.
Many states have restricted or banned planting common barberry, and efforts continue to control their spread.
How to Identify Barberry
Barberry is a thorny shrub that’s easy to recognize once you know what to look for:
Stems: Brown or reddish, with sharp single spines at the nodes.
Leaves: Small, oval, often clustered in rosettes; sometimes purplish on ornamental types like atropurpurea.
Flowers: Small, yellow, hanging in clusters in spring.
Berries: Bright red, oblong, ripening in late summer and lasting through winter.
Japanese barberry (Berberis thunbergii) has smaller, rounder leaves, while common barberry (Berberis vulgaris) has toothed leaves and slightly larger berries.
Berberine and Plant Chemistry
One of the most notable compounds in barberry is berberine, a yellow alkaloid found in its roots and bark. Historically, its bright color and strong taste caught the attention of herbalists and healers.
What makes berberine especially interesting is how it interacts with other plant compounds. Research has shown that in some plants, berberine’s effects are enhanced when combined with other constituents, highlighting the importance of synergy in herbal medicine【Yarnell 2015; Stermitz et al. 2000】.
This is a reminder that plants rarely act in isolation—their gifts come as a whole package.
Traditional & Historical Uses
Barberry has a deep history of use across cultures:
Avicenna’s Canon of Medicine (11th century) described barberry as cooling and drying, useful in balancing excess heat.
King’s American Dispensatory (late 19th century) listed it as a plant of interest for digestive support and liver-related imbalances.
In Persian cuisine, dried barberries (zereshk) add a tart burst of flavor to rice dishes such as zereshk polo.
Culinary uses: The berries can be made into jams, syrups, or jellies, offering a sour brightness similar to cranberries.
A Simple Recipe: Zereshk Polo (Barberry Rice)
One of the most beloved culinary uses of barberries comes from Persian cuisine, where the berries are called zereshk. They bring a burst of tartness to rice dishes, balancing savory and sweet flavors. Here’s a simple version you can try at home:
Ingredients
2 cups basmati rice, rinsed and soaked
½ cup dried barberries (substitute currants if needed)
2 tbsp butter or ghee
1 tbsp sugar (optional, softens the tartness)
Pinch of saffron (optional, for color and aroma)
Salt, to taste
Instructions
Cook the rice until fluffy, then set aside.
Soak the dried barberries in warm water for 10 minutes, then drain.
In a pan, melt butter, add barberries, and gently sauté for 2–3 minutes with sugar and saffron.
Toss the barberries over the rice before serving.
This dish is often paired with chicken or lamb, but it’s just as delicious on its own as a fragrant, colorful side.
Safety Considerations
Barberry is strong and should be approached with respect. Traditional texts note that it was not used during pregnancy and that it was often combined with other herbs rather than taken alone. As with any plant, it’s important to learn its history, respect its potency, and use discernment.
Reflections: Finding Value in the Invasives
As I walk through the woods of Connecticut, I often see long hedges of barberry shrubs tracing the lines of old stone walls, their thorny branches catching the light and their bright berries glowing like beads against the green. On my own land, I’ve noticed how stubbornly they come back even after cutting, a reminder of their resilience and will to thrive. While their invasiveness is undeniable, I can’t help but pause and reflect on the paradox of their presence—how a plant can be both disruptive and still undeniably beautiful.
For me, working with barberries is less about judging it as “good” or “bad” and more about listening to what it has to teach. My early experience planting it unknowingly and my later encounters with its persistence in the wild both remind me that the land is always shifting, always asking us to learn. By paying attention to the plants that thrive—whether native, naturalized, or invasive—we deepen our relationship with place and become more adaptable ourselves.
