Dwarf Rhubarb Gunnera magellanica
ABOUT
Gunnera magellanica, commonly referred to as dwarf rhubarb, is a perennial plant that boasts a distinctive and vigorous appearance. It features a dense rosette of rounded, deeply veined leaves that are charmingly scallop-edged, giving it a rich, textured look. The surface of the foliage is a vibrant green, adding a lushness to its surroundings. As the seasons change, dwarf rhubarb showcases tiny reddish-brown flowers which are rather inconspicuous when compared to the attractive foliage. These flowers cluster along spike-like structures, called inflorescences, which protrude from the plant's center. Following flowering, small, inedible green fruit can develop, turning to a brownish hue upon maturity. The overall form of dwarf rhubarb is low-growing and ground-covering, contributing to its popularity in garden landscapes where it creates a verdant, mat-forming layer. The texture of the leaves along with the subtle hues of the blooms and fruit can add visual interest and a touch of wildness to certain garden spaces. Despite its name, dwarf rhubarb is not related to the common rhubarb that is cultivated for culinary uses, and it should not be consumed.

WaterDwarf rhubarb prefers consistently moist soil, so it is important to water it regularly. Depending on the climate and weather conditions, watering may be necessary once or twice a week. A good method is to provide a deep watering that allows moisture to reach the root zone without flooding the plant. You might need to adjust the frequency during hot, dry periods by watering more often. Generally, aim for about one to two gallons of water per week, ensuring that the soil remains damp but not waterlogged.
LightDwarf rhubarb thrives in partial shade to full sunlight conditions. The ideal spot for this plant would be where it receives bright, indirect light or morning sunlight with protection from harsh afternoon rays. Avoid placing it in deep shade as this can reduce its vigor.
TemperatureDwarf rhubarb grows best in temperatures ranging from 50 to 75 degrees Fahrenheit. It can tolerate temperatures as low as 30 degrees Fahrenheit, but frost can be damaging. The ideal climate for this plant is cool and temperate, avoiding extremes of heat and cold.
PruningDwarf rhubarb benefits from occasional pruning to remove dead or damaged leaves and to maintain its size and shape. The best time to prune is in the fall after the leaves have died back or early spring before new growth begins. Lightly prune as needed to keep the plant healthy and attractive.
CleaningAs needed
SoilDwarf rheum requires a peaty, acidic soil mix with pH 5.5-6.5. Aim for high organic matter, and ensure good drainage to prevent root rot.
RepottingDwarf rheum should be repotted every 2 to 3 years as they are slow growers and like to be somewhat pot-bound.
Humidity & MistingDwarf rheum thrives in high humidity environments, typically above 60%, closely mimicking its native habitat conditions.
Suitable locationsIndoor
Ensure bright indirect light and high humidity for indoor dwarf rheum.
Outdoor
Plant in partial shade with moist soil for outdoor dwarf rheum.

Life cycleThe life of Gunnera magellanica, commonly known as dwarf rhubarb, begins with seed germination, which is influenced by the temperature and humidity of its environment, generally occurring in moist, peaty soils. The seedling stage follows, during which the first leaves and a root system develop; this stage is critical for absorbing nutrients and establishing the plant. As the plant enters the vegetative growth stage, leaves expand, and the distinctive leaf shape of dwarf rhubarb becomes recognizable, along with a thick, fleshy stem for photosynthesis and storage. Once mature, Gunnera magellanica produces small reddish-brown flowers, clustered in spike-like inflorescences, which can lead to pollination and seed set if the male and female flowers are brought into contact, often by wind or insects. The plant then enters a period of senescence at the end of the growing season, with above-ground parts dying back in response to colder temperatures while the rhizomes persist, storing energy for the next growing season. This perennial cycle repeats annually, ensuring the continuation of the species.
PropogationPropogation time
Spring-summer
Propogation: The most popular method of propagating Gunnera magellanica, commonly known as dwarf gunnera, is by division. The best time to divide this plant is in the early spring, just as the plant is beginning to grow. To propagate by division, carefully lift the plant from the ground with a shovel and gently separate the crowns, ensuring each section has a portion of root attached. It is important not to damage the roots excessively during this process. Once divided, the sections can be immediately replanted into soil that is moist and well-draining. This will give each new section the best chance to establish itself and grow into a separate plant.
