Japanese Laurel
Aucuba japonica
The easygoing shade shrub with gold-speckled leaves and bright red winter berries.
Partial shade
Every 7–14 days
USDA 6–10
6–15 ft · 1.8–4.6 m
Overview
Looking for something that thrives where most shrubs sulk? Japanese Laurel (Aucuba japonica) is an evergreen shade lover that takes the deep, dry shade under trees in stride and asks for very little once it's settled in. The glossy leaves, often dusted or splashed with gold, light up the shadiest corner of a garden.
This one earns its easy reputation honestly. It shrugs off poor soil and urban pollution, handles a hard prune without complaint, and grows happily either outdoors in zones 6 through 10 or indoors in a pot. Slow and steady is its pace, reaching 6 to 15 feet (1.8 to 4.5 m) over time.
A quick thing to know about the berries: aucuba is dioecious, so male and female plants are separate, and only the females produce those cheerful red drupes that ripen in fall and hang on into spring. They need a male planted nearby to set fruit, unless you go with the self-fertile Rozannie.
Care
The short version: give Japanese Laurel partial to full shade, keep young plants evenly moist while they root in, then let the top half of the soil dry between waterings once they're established. Plant it in well-drained soil with some organic matter, feed it just once in spring, and prune in late winter to early spring to keep a tidy, rounded shape. Steer clear of soggy soil and full sun and this shrub pretty much looks after itself.
Light
Partial to full shade is the sweet spot here, though a little morning or partial sun is fine. Strong direct sun will scorch the leaves, so keep it out of harsh exposure. If you're growing one of the gold-dusted forms, plant it in deep shade, since that's where the variegation holds its color best.
Water
While young plants are getting their roots down, keep the soil evenly moist and water roughly every 7 to 14 days. Once established, aucuba is very drought tolerant, so let the top half of the soil dry out before you water again. The one thing to avoid is soggy, wet soil, which leads straight to root rot.
Soil
Aucuba isn't picky and grows in loam, clay, or sandy soil as long as there's some organic matter and good drainage. It even shrugs off poor soil and urban pollution. Aim for a pH between 5.5 to 7.0 and it'll be content.
Temperature
This shrub handles a wide range, from 0°F to 86°F (-18°C to 30°C), and is hardy across USDA zones 6 through 10. Since the leaves stay on all winter, give it shelter from cold drying wind so the evergreen foliage doesn't brown.
Humidity
Average household and garden humidity is all aucuba needs, with no particular target to hit. Just keep an eye on indoor plants, because very dry air invites spider mites.
Feeding
There's not much to do on the feeding front. Aucuba is a light feeder, so a single application of balanced slow-release fertilizer in spring covers it for the year.
Pruning
Prune in late winter to early spring to shape the plant, doing it before new growth starts since the flowers bloom on new wood. Cut leggy stems back to keep a dense, rounded habit, and don't worry about going hard, because aucuba takes heavy pruning well.
Repotting
For container or indoor plants, plan to repot every 2 to 3 years. Time for a bigger pot if you spot roots circling inside or poking out the drainage holes, water draining straight through, or stunted growth with yellowing leaves.
Size & spacing
Give this one room to spread, since it can reach 6 to 15 feet (1.8 to 4.5 m) tall and 4 to 9 feet (122 to 274 cm) wide over time, all at a slow pace. Working with a smaller space? The dwarf Nana stays compact.
When to plant
Spring and fall are both fine for getting Japanese Laurel into the ground, ideally in a shaded, wind-sheltered spot. Here's roughly how the year plays out for planting, flowering, and fruit.
Northern hemisphere
Southern hemisphere
Typical months for a temperate climate: start earlier in warm zones, later where spring frosts linger.
- Plant: Spring or fall in a shaded, wind-protected site
- Harvest: March to April (small reddish-purple flowers); red drupes ripen in fall and persist into spring
Hardiness
USDA hardiness zones: 6–10
Temperature: down to -23°C
Troubleshooting
Japanese Laurel is a tough customer, but a few things still trip it up. Most trouble traces back to too much sun, soggy soil, or a handful of common pests, and each one has a clear fix.
Wilting plant with dark, mushy roots
When the soil never seems to dry out and the plant wilts anyway, root rot is usually the culprit, and it takes hold in waterlogged ground. Dig down and you'll find roots that are brown, soft, and smelly instead of firm and white. Get the drainage sorted out and ease off the water right away. Plants that are too far gone are best pulled and tossed, then replant any healthy ones into soil that drains well.
Fix:
- Improve drainage and stop overwatering
- Remove and discard severely affected plants
- Replant healthy specimens in well-drained soil
Sticky leaves with bumps or cottony specks on the stems
Sticky leaves and a dusting of black sooty mold usually mean sap-sucking pests have moved in. Flip the leaves over and check the stems: armored bumps point to scale, white cottony fluff means mealybugs, and fine webbing on an indoor plant is a sign of spider mites. Wipe off or prune away the light spots, then treat with horticultural oil or insecticidal soap, and give houseplants better air flow to keep things in check.
Fix:
- Wipe off or prune lightly infested parts
- Treat with horticultural oil or insecticidal soap
- Improve air circulation for indoor plants
Leaves scorched black on the sun-facing side
Notice the worst damage on the side facing the sun? That's a pretty clear sign of too much direct sun, and young leaves take the hit first while the shaded interior stays a healthy green. Cold or hot dry wind can scorch the foliage too, so the fix is to move the shrub somewhere shadier and out of the wind, give it afternoon shade if your summers run hot, and snip off the leaves that are too far gone.
Fix:
- Relocate or transplant to a shadier, wind-protected location
- Provide afternoon shade in hot climates
- Remove badly damaged leaves
Toxicity
Aucuba sits on the low end of the toxicity scale. The fruits and leaves hold a glycoside called aucubin that can cause an upset stomach if eaten, so it's worth knowing how different animals and people react.
Toxic to
Cats · Dogs · Horses · Rabbits · Livestock · Birds · People
Cats Mild
A cat that nibbles a leaf or berry tends to drool first and then vomit, and things usually settle on their own. If it drags on, give your vet a call.
Dogs Mild
Dogs typically get vomiting and loose stool, which stays mild and tends to clear up within a day.
Horses Mild
The aucubin leaves horses off their feed with a queasy, unsettled stomach, so keep any clippings well out of their reach.
Rabbits Mild
Rabbits get the same stomach upset, and since they're so small it takes very little to bother them, so offer them no part of the plant.
Livestock Mild
Goats, sheep, and cattle that graze on it can start drooling and end up with a sour stomach, so fence the plant off.
Birds Caution
Wild birds happily eat the ripe red drupes and spread the seed without any harm, but it's safest to keep cage birds away from the leaves.
People Caution
No part of the plant is meant to be eaten, and swallowing the fruit or leaves brings on nausea and vomiting. Handling the foliage is perfectly fine and won't irritate your skin, so just keep the fruit away from small children.
Foliage does not cause contact dermatitis and is safe to touch; keep berries and leaves away from pets and small children.

Varieties
Part of the fun with aucuba is choosing your leaf pattern, and a couple of cultivars are bred for smaller size or easy fruiting. Here are a few favorites and what sets each one apart.
Variegata (Gold Dust)
Glossy dark green leaves splashed heavily with yellow speckles, and that gold dusting comes through brightest when the plant sits in full shade.
Picturata
Each leaf has a bold golden-yellow center ringed by a green margin that's flecked with yellow of its own.
Nana
A slow-growing dwarf that stays compact at roughly 3 feet by 3 feet, so it's the one to reach for in tight spots.
Rozannie
A compact, self-fertile pick that sets its red berries on its own, no male plant required nearby.
How to propagate
Want more aucuba? You've got three easy-to-moderate routes, and all of them are beginner-friendly. Here's how each one works and what to expect.
Stem cuttingsEasy
Summer to early fall (semi-hardwood cuttings) · 6 to 10 weeks to root
Take semi-hardwood cuttings from summer into early fall, and you can expect roots in 6 to 10 weeks. One tip worth following: label each cutting as male or female so you know what you're getting later.
SeedModerate
Sow ripe seed in fall · Several weeks to germinate; slow to reach size
Sow ripe seed in fall and it'll take several weeks to germinate, then a while longer to size up. Seedlings come out variable, and you can't tell male from female until the first flower shows.
LayeringEasy
Spring to summer · Several months to root
Peg a low branch down into the soil any time from spring to summer and let it root in place. It's an easy, hands-off method, though it does take several months for roots to form.
Myths
Aucuba is poisonous to touch, so you shouldn't handle it without gloves.
The foliage is safe to touch and won't trigger contact dermatitis. The toxicity only matters if the fruit or leaves are actually eaten, so simple handling is no problem.
Any aucuba you plant will reward you with bright red berries.
Not quite. The plant is dioecious, meaning male and female flowers grow on separate plants, and only females carry those red drupes. A female needs a male nearby to fruit, though the self-fertile cultivar Rozannie can do it alone.
