What is Prairie Smoke
Prairie Smoke is a perennial wildflower native to North America. Scientifically known as Geum triflorum, it grows up to 8” tall in full sun and well-drained soil. Blooming pink flowers in Spring that hang upside down, it attracts bumblebees who are attracted to the nectar. It expands by seed and through clump-forming rhizomes. 
After the blooming period ends the flowerheads become erect, and seeds form in dense clusters. Each seed will have a long feather-like tail, and it is these dense clusters that give Prairie Smoke it’s common name.
Prairie Smoke is a beautiful and compact perennial that can be a great addition to any garden. It’s small size make it truly ‘residential friendly’ in that it won’t be overbearing or flop.
The native range of Prairie Smoke is huge and spans vastly different ecosystems. From thin sandy soils to prairies, it can grow. However, there is evidence that local ecotypes have adapted to these regions. So, while it is generally safe to plant in medium to dry soil conditions, if you have the ability to source your seed/plants from local ecotypes, you should do so.
Native Range of Prairie Smoke
The primary native range of Prairie Smoke is Western United states from Washington to California, over to Illinois, and the Canadian Provinces of British Columbia to Ontario, even stretching into the Yukon.

What are the Benefits of Prairie Smoke
The flower heads of Prairie Smoke look great for up to two months. The combination of red sepals and light red petals give it a pink hue that goes well with anything.
Prairie Smoke is generally 6-8” tall (9-12 cm), making it one of the smaller flowering native plants that can be considered showy. But this small stature make it an option for growing right next to a sidewalk, driveway, or to serve as a quasi-natural divider between species.
Prairie Smoke is mostly native to the drier and sandier Western United States. This drought tolerance means it is low maintenance too.
Identification and Characteristics of Prairie Smoke
Like some other members of the Geum genus, Prairie Smoke will form a rosette of basal leaves. Individual leaves are roughly 3-5” long by 1-1.5” wide. And individual leaf has an odd-pinnate, pinnatifid, or lyrate structure with 6-18 lateral leaflets & a single terminal leaflet.
Some of the lower basal leaves will persist all Winter. However, similar to Foxglove Beardtongue, the leaves will often change to a red or purple color. But, if you come across some barren soil and notice leaves that resemble Prairie Smoke….well you probably found some.
The flowering stalks terminate into an umbel of typically three perfect flowers that droop upside down. Sometimes up to 7 flowers can occur in an umbel, though it is rare. Each umbel will have two leafy bracts at it’s base. The bracts are roughly linear in shape and a reddish color.
And individual flower is ½”-1” long and has approximately the same diameter. A flower will have about five red to purple-red sepals and five white to pale-red petals giving it an overall pinkish color. Additionally, 5 linear floral bracts will extend outward from each flower, these bracts being the same color as the sepals. 
Numerous styles will protrude out the flowerhead, although they are quite small during the active blooming period.
Flowers will bloom in late Spring for 4-8 weeks. After flowering, the nodding flowerheads turn right side up and form very dense achenes of seed, with each seed being attached to one of the aforementioned styles. These styles elongate as seed ripens, and grow fine hairs. This gives it a ‘smokey’ appearance.
How to save seed from Prairie Smoke
To save seed from Prairie Smoke, wait until the hairs begin to turn white. Then, gather them from the seed head as soon as they begin to loosen, as the wind will eventually blow them away. A mesh bag with drawstring may help with seed collection, as you could ‘bag’ the seed head prior to it being dispersed. One researcher gathered ~140 seeds from a single mature plant. 
It has been noted that it could be beneficial to cut styles right before harvesting to prevent entanglement. Also noted that rainstorms can cause almost total dispersal of the seed, so one must pay close attention.
Grow and Care for Prairie Smoke
When it comes to soil texture, Prairie Smoke prefers sandy or gravelly soil that is somewhat barren. And the soil must be well drained. Shallow soils are also fine, as Prairie Smoke does not tolerate competition from taller plants well. Although it has been found to grow in clay in northern Nevada,
For moisture, Prairie Smoke will prefer medium-moist to dry conditions and well-draining soil. Although there is ample evidence that it is quite adaptable and can tolerate periods of high moisture in early Spring, followed by drought in late Summer months. 
So, what does this mean? Well, as long as your soil can drain and has full sun, you can probably grow it. But if you live in a more extreme environment (dry thin soils or deep prairie) then you should make an effort to get your plants/seed sourced from local ecotypes.
If grown in it’s preferred growing conditions, Prairie Smoke will spread via underground rhizomes. If the clump gets too large, you can divide it in the Spring.
Prairie Smoke will not require supplemental fertilizer.
How to Grow Prairie Smoke from Seed
Prairie Smoke isn’t too difficult to grow from seed. It doesn’t require cold stratification to germinate, but research found moderate increases in germination rates. The tiny seeds should be surface sown, as sunlight will help break dormancy. To achieve the stratification requirements, and due to the small size of the seed it is best to winter sow Prairie Smoke.
But, the seeds must be on the surface of the soil and in constant moisture for several weeks to germinate, regardless if they are stratified or not.  And because of this, you should really consider Winter Sowing the seed, as the soil in early Spring will hold moisture much better than under the hot mid-summer sun.
Also – seed viability may vary considerably year to year. As researchers found germination rates varied from 14% to 80% (unstratified seed) depending on the year harvested.
If you are unfamiliar with Winter Sowing, I strongly suggest you check out our step-by-step guide.
But for planting, simply fill a suitable container with moist potting soil, and gently scatter/press the seed in. Then place the container in a location that gets morning sun and afternoon shade.
Establishing Prairie Smoke
Prairie Smoke seedlings are quite tiny, and should be separated or thinned once true leaves develop.
But keep seedlings well watered the first year so they can survive any droughts. You can expect to get blooms the second year after germination/transplanting. If you wait to transplant until Autumn, you may not get any blooms until year three.
Propagating Prairie Smoke by division
Prairie Smoke can be divided in Spring every 3rd to 5th year. Dig up the clump in early Spring, just as plants are emerging. Then, use a hose to soften and separate root clumps. Each root clump can be immediately replanted in a new location to make a new plant.
It is important to do this in very early Spring for several reasons. First, you do not want to separate/transplant plants when they are near blooming or making seed, which Prairie Smoke does in Spring. Second, the ground soil and air temperatures are generally moist during Spring, reducing water demand. Third, the reduced water demands allows the plant to reattach roots to soil, reducing transplant shock.
Wildlife, Pests, and Diseases associated with Prairie Smoke
Deer and Rabbits
Deer and rabbits tend to leave Prairie Smoke alone. In fact I’ve never seen any damage on my plants, and I have quite a few now lining sidewalks around my home. However, out west with less vegetation available, mule deer have been reported to forage in Fall. 
Prairie Smoke is not preferred forage source by mammals. It is however fed on by pronghorn and elk, and occasionally by cattle. 
Prairie Smoke is generally disease free.

Uses of Prairie Smoke
Considering the natural habitat of Prairie Smoke is empty, rough, barren soil as it dislikes competition, it is really a great choice for formal mulched flower beds. It’s compact size make it an excellent choice as a filler plant or lining walkways.
It can also serve as a small border between species, assuming it doesn’t get overcrowded. And since it can spread via rhizomes, you can always get more for free!
Furthermore, the shallow root system make Prairie Smoke a possible choice for growing in a pot or container. However, you should overwinter pots in unheated garages, sheds, or take measures to ensure the pot doesn’t freeze solid for prolonged periods.
For companion plants, Prairie Smoke will grow well with other dry to medium-moisture loving plants in full sun. Some good choices would be the following;
The leaves and stems of Prairie Smoke have been tested and found to have antimicrobial properties. 
Native American Uses
- An infusion of the plant was taken as cough medicine
- Roots and grease were used as salve to open sores, rashes, and other skin issues.
- Infusion of roots was used to treat swollen eyes
- Roots could be used as a ‘love medicine’ for women who wanted to win back a man
- Infusion of roots could be used to treat colds, fevers or lack of appetite
Prairie Smoke is one of the more residential friendly plants you can grow in your yard. It’s small size and long bloom time allow it to look good for a long period in Spring.
