Traditional uses

Long before it drew scientific attention, black hawthorn was a familiar presence to the Indigenous peoples of the Pacific Northwest, who ate the small haws fresh or dried them for winter stores, and put the tree's formidable thorns to work as fish hooks, awls, and probes. Its European cousins, Crataegus monogyna and laevigata, carry an equally long reputation in Old World herbalism, where hawthorn has traditionally been used as a gentle tonic for the heart and circulation for centuries. Herbalists in North America have carried that same tradition forward with the native black hawthorn, steeping its berries and blossoms into mild, reddish teas meant to be taken steadily over time rather than as a quick fix.

Growing guide

Sun
Full sun to light partial shade for the best bloom and fruit set
Soil
Adaptable to a wide range of soils but happiest in moist, well-drained ground near a stream or seasonal wet spot, its natural habitat
Water
Regular water while establishing; mature trees are quite drought tolerant thanks to a deep root system
Planting
Grow from stratified seed (haws often take a year or more to germinate) or start with a nursery sapling in fall or early spring; give it room, as the thorns are formidable, and keep young trees away from foot traffic

Fresh to dried

Harvest
Gather flowers in late spring just as they open, leaves in spring while still tender, and berries in fall after the first light frost has sweetened them and turned them deep purple-black
Drying
Spread berries and flowers in a single layer on a screen or tray in a warm, airy, shaded spot until fully dry and slightly wrinkled, turning occasionally for even drying
Storage
Keep dried berries and flowers in an airtight glass jar away from light and heat, where they will hold their character for up to a year
Best forms
Dried berries and dried flowers are the most versatile for tea, syrup, or jelly making

Traditional preparations

Featured preparation

Hawthorn Berry Tea

A mellow, faintly tart infusion long favored in folk herbalism as a gentle daily tonic for the heart and circulation.

How it's made. Traditionally, a tea is made by steeping 1 teaspoon of dried, lightly crushed hawthorn berries in 250 ml of just-boiled water for 10 to 15 minutes, then straining before drinking.

Secondary preparation

Hawthorn Flower Tea

A lighter, more floral infusion made from the spring blossoms, used in the same traditional spirit as the berry tea.

How it's made. Steep 1 teaspoon of dried hawthorn flowers in 250 ml of just-boiled water for about 10 minutes, then strain.

Pairs well with
  • Motherwort
  • Linden flower
  • Rose hip
Substitutes
  • English hawthorn (Crataegus monogyna or Crataegus laevigata), the closely related European species most often used in commercial hawthorn preparations
Choose it when

When you want a gentle, old-fashioned ally for the heart, gathered from the same thickets where it has grown wild for centuries.

Did you know?

The genus name Crataegus comes from the Greek word kratos, meaning strength, a nod to the tree's notoriously hard, dense wood. Coast Salish and other Pacific Northwest peoples put that toughness to work, using black hawthorn's long thorns as fish hooks, sewing awls, and even tools for piercing ears.

Safety

Hawthorn can interact with heart medications like digoxin, beta blockers, and blood pressure drugs, so check with a doctor if you take any of these. Don't chew the seeds inside the berries, and use caution during pregnancy or breastfeeding since safety isn't well established.
