Japanese columnar Rubus · large red fruit · June–August harvest

Rubus crataegifolius RASPBERRY TOWER® ‘Hara-rasp’

The raspberry that grows… like a tree! 🍓🌳

Family: Rosaceae · Pot diameter: 19cm · Height: approximately 30–45cm

Columnar habit 1.2 × 0.6m
Strong self-supporting stems
Fruit over 2cm
Hardy to about −25°C

Rubus crataegifolius RASPBERRY TOWER® ‘Hara-rasp’ builds a narrow vertical column filled with large glossy red fruit from June into August. Strong stems remain clustered, reach about 1.2m and usually stand without a large trellis, allowing the plant to fit beautifully in a small garden or generous container. It is a genuinely different Rubus: architectural, hardy and productive within minimal width, making a striking fruiting accent beside a door, path or compact terrace.

Retain three to five strong vertical stems and after harvest remove only those that have just fruited.

Plantarium 2022 Bronze award for its original columnar habit and value in small spaces.

What makes it special

RASPBERRY TOWER® stands out for naturally vertical architecture, strong stems and large fruit within an exceptionally narrow footprint.

True columnar habit

The mature shrub stays around 60cm wide and grows mainly upwards.

Large glossy fruit

Red berries over 2cm appear successively from June to August.

Strong stems

The compact vertical bundle usually needs only a discreet guide, not a trellis.

Why you will love it: It creates the impression of a small fruiting tower and fits where a classic raspberry row is impossible.

In the garden & on the terracePositioning & plant combinationsA bright position with one slim vertical guide, cool roots and free picking access.

Planting position

Ideal position

Plant in sun or bright partial shade, allowing 60–80cm between plants. In very hot areas choose morning sun.

Colour & compatibility

Compatible combinations

Chive flowers, silver sage and low scabious emphasise the vertical silhouette.

Allium tuberosum — White heads and narrow foliage continue the clean vertical line.
Salvia officinalis — Silver-green aromatic foliage creates a stable low base.
Scabiosa columbaria — Airy lilac flowers move around the column without hiding fruit.

Care at a glance

Light

Sun or bright partial shade; afternoon protection during prolonged heat.

Water

Even moisture from flowering until the end of harvest.

Climate & hardiness

Very good hardiness to about −25°C in the ground, with root protection in an exposed container.

Safety

Wash fully ripe fruit before eating.

Detailed careComplete care guideSoil, watering, support, feeding and cultivar-specific prevention.

Soil & roots

Plant in deep fertile soil that drains well yet stays cool. Add organic mulch around the roots without covering the cane bases.

Watering

Water deeply when the top few centimetres dry. Even moisture from flowering to harvest helps fruit fill uniformly.

Support & shape

Retain 3–5 vertical stems around one slim central guide or small cage, without spreading them into a broad fan.

Feeding

In early spring add mature compost and a balanced fruit-plant feed according to its label. Avoid excess nitrogen.

Summer care

Mulch the roots, remove weeds by hand and pick frequently. During prolonged heat, provide light afternoon shade.

Prevent problems

Keep gaps between vertical stems, water deeply and remove fruited stems after late August.

From flower to basketFruiting & harvestSimple guidance on pollination, ripening, picking and protecting the crop.

Pollination

It is self-fertile and crops alone. Insects help large red fruit fill evenly.

When it ripens

Fruit ripens successively from June into August on stems grown the previous year.

How to harvest

Pick when fruit is vivid red, slightly soft and releases without pressure.

Fruit protection

Secure netting to a separate frame as fruit begins to colour and leave easy access.

After planting: train the strongest stem vertically and do not spread the narrow bundle into a fan.

RASPBERRY TOWER® fruits on canes grown the previous year. After the final picking remove only fruited canes at the base and tie new green canes into their place.

Build

New generation

Train new green canes separately from fruiting ones.

Action: Train new green canes separately from fruiting ones.

Retain: Retain 3–5 strong new canes.

Train

Fruiting cane

Spread last year’s canes over the wires and remove only overlong laterals.

Action: Spread last year’s canes over the wires and remove only overlong laterals.

Retain: Retain short well-lit laterals with flowers and fruit.

Renew

Changing generations

After picking cut brown fruited canes at the base.

Action: After picking cut brown fruited canes at the base.

Retain: Tie green new canes to the vacant wires.

New / productive — retainOld or exhausted woodCut point

Clean tools

Use sharp, clean tools suited to the diameter of the wood.

Winter check

Renew ties and remove only broken or diseased wood.

Do not do this: Do not confuse new green canes with brown fruited ones; the green canes are next year’s harvest.

Development over timeHow the plant developsA realistic path from establishment to mature form.

New growth

Strong upright stems form a narrow bundle around the central guide.

Flowers and fruit

Large red fruit ripens on short laterals along the column.

Mature renewal

After August fruited stems are removed and new ones take their place vertically.

SpringThe narrow year-old column fills with flowers while new vertical stems rise in the centre.

June–AugustLarge red fruit appears successively along the full well-lit height.

Columnar habit comes from narrow branching angles and strong mechanical cane strength, not constant tying or tipping.

What to expect after planting: Strong upright stems form a narrow bundle around the central guide.

History & originCultivar originA Japanese creation by Toshihiko Hara, protected as ‘Hara-rasp’ and awarded Bronze at Plantarium 2022.

RASPBERRY TOWER® was created in Japan by breeder Toshihiko Hara, working with Rubus crataegifolius, an Asian species known for strong upright stems and good hardiness. The aim was a fruiting Rubus growing as a narrow column rather than a broad row.

Among the new selections, ‘Hara-rasp’ stood out: stems remained clustered and strong enough to stand almost unaided, while large glossy red fruit over 2cm ripened from June to August on short laterals.

The selection received European protection as EU 20221969 and was released as RASPBERRY TOWER®. In 2022 it received a Bronze award at Plantarium, recognising its innovative narrow architecture and value in modern small gardens.

Greenleaf for Plant NerdsScientific details nobody asked forBotanical detail behind the plant's appearance and behaviour

Rubus crataegifolius

This Asian species differs from European Rubus idaeus in cane strength, leaf form and naturally vertical architecture.

Column mechanics

Narrow branch angles, greater basal diameter and increased lignification allow stems to resist bending under wind and fruit load.

Frequently asked questions

Six practical answers for choosing, growing, harvesting and pruning this exact cultivar.

01Does it need another plant?

It is self-fertile and crops alone. Insects help large red fruit fill evenly.

02How large does it become?

1.2m high and approximately 0.6m wide, with the habit described above.

03Is it suitable for a container?

Yes, in a heavy 45–55-litre container with a slim vertical guide and protection from wind throw.

04When is the fruit picked?

Fruit ripens successively from June into August on stems grown the previous year.

05Does it need a trellis?

Not a large trellis. One slim vertical guide or small cage keeps the narrow bundle safe in wind.

06When should it be pruned?

After harvest remove fruited stems at the base and retain 3–5 new vertical ones.
