Rosa palustris, swamp rose, is a species rose native to the eastern United States. This means something considering most of the roses grown in American gardens are not from North America.
It is called swamp rose with good reason. Rosa palustris likes boggy, wet areas.
Swamp rose likes wet soil but grows beautifully in gardens with average soil moisture.
Rosa palustris has clear pink semi-double flowers that bloom in May-June in the Piedmont region. In cooler areas, flowering is for a roughly six week period from June to July. Most guides recommend that swamp rose can grow to 6′ tall. I have seen old plants get to 7′-8′ in the garden. Foliage, like most of the species roses, is relentlessly healthy.
Rosa palustris (swamp rose) is easy to grow in the garden.
Winter hardiness is excellent, zones 4-9. It is found growing in the natural landscape from Maine to Florida. Swamp rose occurs naturally in swamps, bogs, and places with intermittent flooding (including road size ditches). Thus, gardeners wishing to grow roses in wet parts of their landscape could do worse than this rose.
Over time, swamp rose will spread via suckers, making it a solid choice for naturalizing. The thorns are wicked. Thus, Rosa palustris a great candidate for a barrier hedge.
Birds like the hips that form in fall and assist in the spread of swamp rose via the seeds they eat. Many of the older species roses have spectacular crimson hips if flowers are allowed to mature on the plant.
The plant is graceful in the garden, as the branches tend to be long and arching. Habit is bushy and full. Rosa palustris can handle light shade, but please do not overdo this. Full or mostly sun is best. It grows best in rich slightly acidic soil.
