Gunnera Manicata is a spectacular garden plant that needs plenty of room - its giant leaves can grow up to 3 metres across. It is a clump-forming herbaceous perennial plant, meaning that its foliage dies back in winter to re-emerge new growth from its rootstock in the following spring. In spring, its stunning, cone-shaped, brown flower heads are first to appear, followed by the new leaves which have a spectacular growth rate. This tall, architectural plant is ideal for planting as a single focus plant, or by the side of large ponds to create spectacular structural displays. Gunnera Manicata has been awarded the Award of Garden Merit given by the Royal Horticultural Society (RHS), which helps gardeners make informed choices about plants.

Caring and Maintenance

Gunnera must always have plenty of moisture available. Cut down dead leaves leaves in autumn and use them to cover the crown, as it must be protected from frost. Propagate by cutting and replanting basal buds in spring or grow from seeds. Protect from cold drying winds.


  • Plant spreading: up to 4m
Suited to moist, poorly drained, and humus rich soil in full sun or partial shade position. Prepare the flower bed by using a garden fork or tiller to loosen the soil. Prepare a hole for the plant, place the plant in the hole and carefully yet firmly fill in with loose soil.

The contemporary range is an exclusive selection of highly desirable garden plants which will create very modern, structural displays that are full of colour and architectural qualities all year round. In this collection highly versatile and low maintenance plants are offered, which can be chosen from varieties of grasses, ferns, bamboos, phormiums, perennials, cannas and bananas to admire and inspire.

The Award of Garden Merit or AGM is an award made to garden plants by the British Royal Horticultural Society after a period of assessment by the appropriate committees of the Society. Awards are made annually after plant trials (which may last for one or more years, depending on the type of plant being trialled) at RHS Garden, Wisley and other RHS gardens, or after observation of plants in specialist collections. This is intended to judge the plants' performance for conditions in the UK.
