Expert tips
The key tip
Install in very organic-rich soil, partial shade or dappled shade, very moist or even marshy. Divide clumps every 2-3 years after flowering.
The common mistake
Planting it in standard border soil or full sun: it yellows, stays dwarf, and won't flower, giving the impression it's dying.
The pro's trick
In dry continental climates, grow it near a water source or in a low area that collects runoff: it'll thrive and burst with vigor.
Care
Regular watering
Creeping gunnera appreciates constantly moist but well-drained soil. Maintain regular watering, especially during vegetative growth in spring and summer. In autumn and winter, reduce watering but don't let the substrate dry out completely.
Ideal partial shade
This plant thrives in partial shade, sheltered from intense direct sunlight which can scorch its delicate foliage. Position it near an east or north-facing window, or in partial shade outdoors for optimal development.
Rich and humus-filled soil
Prepare a rich organic substrate, light and moist, made from peat or leaf mold mixed with coarse sand to ensure good drainage. Avoid chalky soils and prefer a slightly acidic pH.
Moderate fertilization
Apply a balanced diluted fertilizer every 15 days during the growing season (April to September). Favor a fertilizer rich in potassium for stem robustness. Stop fertilizing in autumn and winter.
Light pruning
Regularly remove dead or damaged leaves to maintain a compact shape and improve air circulation. Pinch young stems if you want a denser plant. No drastic pruning is necessary; this species naturally remains small and creeping.
Prevention of rot
Regularly check humidity levels: excess moisture combined with poor air circulation promotes root rot and fungal attacks. Ensure sufficient air circulation and reduce watering if problems occur. Pests are rare on this species in cultivation.
Did you know?
Gunnera magellanica originates from cold Patagonia, where it grows in humid, shaded environments, often near watercourses. It's one of the smallest species in the Gunnera genus: while its tropical cousins can reach several meters, this creeping gunnera doesn't exceed 30 cm, making it a fascinating botanical curiosity for enthusiasts of small alpine plants and specialized collections.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
