Herb-Paris

Paris quadrifolia

In other languages: Eenbes (Nederlands) · Parisette à quatre feuilles (Français)

Grows wild in Belgium.

Herb-Paris is a small woodland perennial with a remarkable structure: a single upright stem carries a whorl of usually four broad leaves, topped by one star-shaped green flower. After flowering, that flower produces a single glossy blue-black berry, which is what its Dutch name, ‘one berry’, refers to. It grows in moist, rich deciduous woodland on chalky or loamy soil, often in ancient woods that have been wooded for centuries. In Flanders it is fairly rare, mainly in old woods on loam such as in the Flemish Ardennes; in Wallonia it is more frequent. Because it spreads so slowly it is a good indicator of ancient woodland, and in a shady wildlife garden it is a real curiosity for the patient gardener.

Caution: Poisonous: the whole plant, and especially the blue-black berry and the rhizome, is poisonous if eaten. The berry looks like a bilberry and can tempt young children; pets should not eat it either. Never pick or dig up herb-Paris in the wild: it is rare in many places.

How to recognise it

Habit: Perennial of 15–40 cm with a single, upright, unbranched stem from a creeping rhizome. Plants often grow in groups.
Leaf: Usually four (sometimes three to six) broad oval leaves in one whorl at the top of the stem, 5–10 cm long, untoothed, with curved veins.
Flower: One star-shaped flower in May–June on a stalk above the leaves: four narrow green sepals, four thread-like yellow-green petals, eight stamens and a dark purple ovary with four styles in the centre.
Fruit/Seed: A single glossy blue-black berry about 1 cm across, ripe in summer. Poisonous.
Roots: A long, thin creeping rhizome just below the surface, sending up new stems each year.
Look-alikes: Without a flower it can be confused with a whorl of sweet woodruff or cleavers leaves, but these have much narrower leaves in several whorls one above the other. The berry looks like a bilberry, but always sits alone on top of a herbaceous plant, never on a shrub.

Flowering: May–June

In your garden

Why grow it?

One of the clearest indicators of ancient woodland: where herb-Paris grows, the wood has often been there for centuries.
A unique silhouette: the ruff of four leaves with one flower and one berry looks like no other plant.
The inconspicuous flower attracts small flies, and the plant belongs to a rich woodland floor with spring flowers.
Its creeping rhizomes slowly form a small group or colony under trees and shrubs.
Of interest from spring to summer: first the flower, then the slowly ripening berry.

Herb-Paris: where does it grow best?

In the wild: moist, shady deciduous woodland on chalky or loamy soil, such as oak-hornbeam and ash woodland and the edges of stream valleys.
An ancient-woodland indicator: it spreads so slowly that it rarely turns up in young plantations.
In the garden: partial to full shade under trees or shrubs, sheltered from hot midday sun.
Humus-rich, moisture-retentive soil that does not dry out in summer; neutral to chalky is ideal, acid sand is not.
A layer of fallen leaves or leaf mould on the ground, as in a real wood, suits it best.

Goes well with

Wood anemone: Flowers earlier in spring in the same spot and then dies back.
Sweet woodruff: A low, scented ground cover for the same moist shade.
Moschatel: A small green spring plant that, like herb-Paris, belongs to ancient woodland.
Oxlip: Yellow spring flowers in moist deciduous woodland on loam.
Male fern: A tall green backdrop in the shade.

Maintenance

Herb-Paris: when and how to plant it?

Buy herb-Paris from a nursery that specialises in native wild or woodland plants. Never dig it up from the wild: it is rare in many places and grows very slowly.
Plant in autumn (September–October) or early spring, before the stems emerge.
Lay the rhizome horizontally, 3–5 cm deep, in loose, humus-rich soil with some leaf mould mixed in. Allow 15–20 cm between plants.
To sow: sow fresh seed in autumn, straight after it ripens, in a pot of woodland soil left outside. The seed needs one or more cold winters and germinates slowly; expect several years before the first flowers.
Water after planting and keep the soil moist in the first year, especially in dry springs.
Cover the soil with fallen leaves and then leave the spot alone as much as possible.

Care

Watering: Only in dry springs and summers; the soil should never dry out completely.
Feeding: Not needed. A yearly layer of fallen leaves or leaf mould is enough.
Soil: Do not hoe or dig around the plants: the rhizome lies just below the surface.
Fallen leaves: Leave autumn leaves where they fall: they feed the soil and protect the rhizome.
Patience: Little happens above ground in the first years. Mark the spot so you do not trample it or dig it up by mistake.

Tip: Plant herb-Paris in a small group of three to five in a permanent spot and then leave it alone: every disturbance sets it back by years.

Pruning and mowing

When: Not needed: the plant dies back by itself in late summer or autumn.

How:

Let the leaves yellow and wither naturally; this way the plant draws its reserves back into the rhizome.
Leave the berry on if you want to collect seed or let the plant self-sow.
Cut the berries off if young children or pets play in the garden.

Caution: Never cut off green leaves: each stem has only one whorl of leaves per year.

Pruning calendar and basic rules

Propagation

Division: In autumn or early spring, cut off a piece of rhizome with a bud and replant it elsewhere at the same depth. Only do this with a well-established group.
Seed: Sow fresh seed in late summer or autumn in a pot left outdoors. Germination can take two years, and the first flowers several more.

Herb-Paris: how does it get through the winter?

Hardy to −30 °C.

Dies back completely in autumn and overwinters as a rhizome underground.
Fully hardy; a layer of fallen leaves protects the rhizome from hard frost and drying out.
In March–April the new stems appear, with the leaves still folded like a closed umbrella.

Diseases and pests

Slugs: They eat the young shoots in spring. Attract hedgehogs and ground beetles with a leaf pile and a log heap.
Drying out: In a spot that is too dry or sunny, the leaves turn yellow as early as June. Choose a cooler spot and mulch with leaf mould.
Slow growth: It takes years for a plant to spread. Do not move it, and be patient.
Poisonous berry: The berry looks like a bilberry. Teach children not to pick it, or cut the berries off.

Through the year

March: The first stems appear, still folded.
April: The leaf whorl opens. Watch out for slugs.
May: Flowering: look for the green star above the four leaves.
June: End of flowering. Water in dry spells.
July: The berry swells and colours.
August: The berry is ripe and blue-black. Collect seed to sow at once.
September: The leaves die back. Plant or divide.
October: Plant. Leave fallen leaves in place.
November: Resting under a layer of leaves.
December: Resting.

You and this species

Did you know?

The scientific name Paris probably comes from the Latin par, ‘equal’: the parts of the plant are very regular, usually in fours.
Almost everything comes in fours: four leaves, four sepals, four petals, eight stamens and four styles.
It spreads so slowly that it is found mainly in ancient woodland that has been wooded without a break for centuries.
