Morus rotundiloba BonBonBerry® Mojo Berry® ‘Matsunaga’ condenses the pleasure of a mulberry into a shrub or small tree suited to a modern garden. It fruits on old and new wood, with successive picking that can extend from May to September rather than lasting only a few weeks. Fruit changes from pale green through pink and red to black, bringing flavour, colour and movement to the crown at the same time.
Use it as a small fruiting focal point beside a terrace or garden seating area. Its rounded crown brings volume above lower planting and keeps the colourful fruit where you can enjoy the display every day.

Mojo Berry combines a dwarf habit, two ages of fruiting wood and a long season.
It flowers and fruits on wood of different ages, so light pruning preserves more productive positions.
The mature form usually stays around 1.5m, with the potential to reach 1.5–2.5m depending on conditions and training.
Chelsea Plant of the Year 2017, Floral Award 2019 and Bronze at GrootGroenPlus 2019 recognised the qualities of ‘Matsunaga’.
Why you will love it: It provides mulberry flavour and foliage without the scale of a large tree and with a much longer picking window.
Plant it in a sunny sheltered position in the ground or a large stable container. Allow 1.5–2.5m in mature height and spread, keeping the crown away from pale paving.
Low companions soften the base without obstructing the fall and collection of dark fruit.
Full sun, preferably in a sheltered position.
Deep watering during establishment and fruit swelling.
Hardy to about −10°C; protect the roots when grown in a container.
Only ripe, washed fruit; the juice stains paving and fabrics strongly.
Use fertile, humus-rich soil that stays moist yet drains freely. Avoid winter waterlogging and exposure to cold dry wind.
Water young plants deeply and during prolonged drought, especially while fruit is filling. Let the surface re-aerate between waterings.
Keep a short trunk or 3–5 main stems and an open rounded crown. It needs neither a pergola nor a rigid central leader.
Apply mature compost in spring. Avoid excess nitrogen, which creates long soft growth and delays wood ripening.
Do not position the mature plant over pale paving, seating or vehicles. Ripe fruit drops and stains.
Keep the crown open, remove shrivelled fruit and prune before mid-winter, when cuts lose less sap.
It is self-fertile and one plant can set fruit. A second mulberry is not needed for pollination.
The season can begin in May and continue successively to September, with several fruit colours present in the crown.
Pick only black, soft fruit that releases with the slightest touch. Place a shallow tray or clean cloth beneath the branch.
Because the fruit does not ripen all at once, check the crown every few days. Enjoy it immediately or refrigerate ripe fruit without crushing it.
After planting: retain a short trunk or 3–5 main stems and water evenly until it is well rooted.
Late autumn to early winter, before mid-winter
Mojo Berry fruits on old and new wood, so it needs only light pruning. Retain a short framework and small fruiting side shoots, removing only growth that overcrowds the rounded crown.
Action: Choose a short trunk or 3–5 well-spaced stems. Remove only broken and very low wood.
Retain: Keep all healthy side shoots that can carry fruit.
Action: In late autumn thin branches that rub or grow into the centre. Do not routinely shorten every tip.
Retain: Keep wood of different ages and small well-lit side shoots.
Action: Remove one old bare branch above a younger outward-facing side shoot and clear one overcrowded stem. Renew only a little each year.
Retain: Keep the short trunk, most old fruiting wood and enough new growth.
Use sharp, clean tools suited to the diameter of the wood.
Remove only broken or diseased material. Main shaping waits until leaf fall.
Do not do this: Do not clip it into a ball or remove all old wood; the cultivar fruits there too.
The young shrub creates a short trunk or a few bases and quickly fills with small side shoots.
Older side shoots and new growth can flower in the same crown, extending harvest.
The mature cultivar remains a large shrub or small tree rather than developing the vast open crown of a common mulberry.
Mature Mojo Berry has a short trunk, an open rounded crown and small side shoots of different ages.
After leaf fall the short branched framework shows where older and younger side shoots coexist.
What to expect after planting: The young shrub creates a short trunk or a few bases and quickly fills with small side shoots.
Japanese plant breeder Hajime Matsunaga selected ‘Matsunaga’ while seeking a mulberry far smaller than traditional trees. Its important distinction was the ability to fruit on both older branches and growth made in the current season, giving repeat crops on a compact shrub.
Plantipp managed its European introduction, and Suttons Seeds launched it in Britain as Charlotte Russe at the 2017 Chelsea Flower Show. It was named Plant of the Year there, bringing immediate recognition, and was also planted in the British royal gardens.
In 2018 it was released across the rest of Europe as Mojo Berry® and BonBonBerry®, always with the cultivar name ‘Matsunaga’. It received EU plant variety right 51394 and won two further honours in 2019, a Bronze Medal at GrootGroenPlus and a Floral Award. Within a few years, a compact Japanese mulberry had become an international garden cultivar.
A mulberry is a multiple fruit: it develops from many neighbouring flowers in one inflorescence. Their small fruits gather along a shared axis to form the single juicy body we pick. The tiny units on its surface therefore represent parts of a whole flower cluster.
In ‘Matsunaga’, small green inflorescences appear on older wood as well as on shoots formed in the same year. Production is therefore not confined to shoots that have passed through a winter; fresh flowers and young fruit can coexist with fruit that is already ripening.
Six practical answers for choosing, growing, harvesting and pruning this exact cultivar.
No. It is self-pollinating and can crop on its own.
Successively from May to September, depending on conditions.
Usually about 1.5m, with the potential to reach 1.5–2.5m in height and spread depending on conditions and training.
When it is black, soft and releases at the slightest touch.
Old and new wood. When pruning, retain some older fruiting wood together with the new growth.
Lightly from late autumn to early winter, before spring growth begins.
