Native Plant of the Week: Prairie Smoke ~ Geum triflorum

Prairie Smoke ~ Geum triflorum
The nodding pink flowers are maturing on the prairie smoke right now and attracting many native bees.

Prairie Smoke is more widely recognized for its fruiting stage when the dried, long pinkish styles blow in the wind.

A native of dry to mesic prairies, this is a great plant for well drained soils and sunny locations.

The attractive bright green basal foliage is fern-like and divided into many leaflets.

The five-parted flowerheads nod downwards and tip upwards as the flowers are setting seed.

This is a great native to mass in designed landscapes near the front edge of a planting. It provides early season flowering and later the pink silky seedheads for interest.



The foliage greens up really quickly after the snow melt. Plant it intermixed with warm season native grasses that will emerge later in the spring for a layered effect.
The tiny Sweat Bees (Lasioglossum species) were pollinating the Prairie Smoke flowers this week.

And some of the first Bumble Bees were pollinating the Prairie Smoke flowers in the warm sunshine. You just have to listen for these big bees, as they loudly buzz pollinate the Prairie Smoke flowers.

Prairie Smoke is native to western North America and the northern midwest region. See map below for range.

  1. Have wanted to ad a few prairie smke plants to the garden for some time. Those bee pictures are a good incentive...

  2. Heather, you mention the bumblebees using a technique called "buzz-pollination". Could you elaborate on what you've observed about this behavior and why this might be a useful strategy?

    1. Some plants have anthers that do not release pollen easily, so Bumble Bees vibrate the anthers so more pollen is released through the anther openings.

  3. I will have to look into these...love them and early plants in the meadow would be wonderful especially for the pollinators.

    1. Donna - I think they'd do well in your landscape and provide some more early season interest.

  4. I tried some of these bareroot in my back garden but they did not make it. I think much too wet. I will try to grow these again where it is hot and dry when I redo my front bed. I just love them. There is a small park nearby where they grow naturally that I've always wanted to visit.

    1. Kathy - sounds like a good relocation plan. Good luck.
