Swamp rose (Rosa palustris) is a native shrub from wetland areas, commonly found along rivers, in swamps, and in wet meadows. It typically reaches 1.5 to 2.5 meters in height, with thorny stems and leaves made up of serrated leaflets. In summer, swamp rose produces large, bright pink, simple, and fragrant flowers that attract many pollinators. In the fall, the flowers turn into small red fruits (hips), adding a splash of colour and providing a valuable food source for wildlife.

Medicinal and Culinary Uses
Swamp rose has astringent, tonic, and diuretic properties. The hips are rich in vitamin C and can be used to make herbal teas, jams, and syrups. In traditional medicine, the petals and leaves were also used in infusions to soothe minor respiratory ailments and mild skin irritations.

Ecological Roles
Swamp rose plays an important ecological role, providing both food and shelter for many animals. Its nectar-rich flowers attract bees, butterflies, and other pollinators, while the hips in the fall offer a food source for birds and small mammals. As a plant suited to wetland environments, it helps stabilize soil and prevent erosion along riverbanks.

 

Swamp rose seeds require cold stratification to ensure germination. See the cultivation notes below for more details.

Growing Notes | Seeds - Swamp Rose

Swamp rose prefers moist to wet, well-drained soils and thrives in full sun or partial shade. This hardy rose is an excellent choice for natural wetland areas, gardens near water bodies, and ecological restoration projects. Once established, it requires minimal maintenance, although an occasional pruning of dead branches can help maintain its vigour and health.

To germinate, the seeds require a five-month treatment process. They must undergo scarification, warm stratification, and cold stratification before sowing.

Thermal Scarification:
Soak the seeds in hot tap water (around 60°C) and let the water cool naturally for 24 hours. Properly scarified seeds should swell. Repeat this step for seeds that have not absorbed water and therefore have not swollen.

Sandpaper Scarification:
Alternatively, seeds can be scarified by rubbing them gently between two sheets of fine sandpaper. Do not press too hard to avoid damaging the seeds. The goal is not to remove the entire seed coat (tegument) but to damage it enough to allow water absorption.

Note: Seeds sown in the fall or winter should not be scarified to prevent premature germination and winter loss.

The seeds require a cold, moist period (winter) followed by a warm, moist period (summer) and a second cold, moist period. Sow them outdoors and leave them for two years or more to germinate.

Stratification (Warm and Cold):
Mix one part seeds with three parts moist vermiculite in a sealed bag (e.g., Ziploc) at room temperature for about 60 days. Then place the bag in the refrigerator for about 90 days.

Sowing:
Broadcast the seeds and lightly bury them no more than five millimetres beneath the soil surface.

Difficult Germination:
Seeds of this species are often water-impermeable, which delays germination. Since germination can take several months after sowing, do not discard seeds if they do not germinate after the first attempt. If necessary, repeat the germination process.
