Genus species:      Common name:     Match: Full Partial
Plant Species: Geum triflorum, prairie smoke


Kingdom: Plantae -- Plants
Phylum: Magnoliophyta -- Flowering plants
Class: Magnoliopsida -- Dicotyledons
Order: Rosales
Family: Rosaceae -- Rose
Genus: Geum
Species: triflorum
Variety: The Palouse phase is var. ciliatum
Common Name: prairie smoke, old man’s whiskers
Species Code: GETR
Origin: The species is native to mesic open grasslands of western North America from British Columbia to California and New Mexico, extending eastward through Canada to Ontario and the northern tier states of the US as far as New York. The Palouse phase, var. ciliatum, has a more limited distribution in western North America from British Columbia to Saskatchewan south to New Mexico.
Rare: no


Form: forb, perennial from short thick rhizomes.
Duration: perennial
Longevity: long-lived
Habitat Type: prairie, shrub thickets, forest
Wetland Indicator Status: not listed


Leaves: mainly basal, short-petiolate, blades 3-15 cm long, oblong to obovate, pinnately divided with up to 30 unequal cuneate segments, the segments deeply cleft; puberulent to hirsute or pilose, appearing grey-green.
Mature height: 8-18 inches
Flowers: mostly cymose, subtended by linear to elliptic bracteoles; calyx turbinate or campanulate to cup-shaped, reddish to pink, 5-lobed; petals 5, yellow, sometimes tinged with red or purple, elliptic, shorter than the sepals and remaining mostly enclosed by them during flowering.
Flower color: yellow
Bloom: May, June, July
Bloom starts on: mid May
Bloom ends on: early July
Fruit: achene, pyriform, about 3 mm long; the style remaining attached and plumose, 2-6 cm long.
Vegetation type:


Characteristics:
Sieversia ciliata in Piper & Beattie 1914.
449,554 seeds/lb for var. ciliatum (USDA NRCS Pullman PMC 2005).
696,000 seeds/lb for the species (Hassell et al 1996).
Geum ciliatum and Sieversia ciliata are synonyms for the western variety.
Reproduces both sexually by seed and vegetatively by rhizomes.
x=7 (University of British Columbia 2003).
n=21 (Baldwin 2004, Hitchcock et al 1969).
Polyploids are known.
Flowers are perfect.
Roots taste like sassafras and can be made into tea.
Fruit is an achene.
Pollinated by bumblebees (Choberka et al 2000)
The plumose style is persistent and aids in wind dissemination of the seed.
Sheep eat the foliage (St. John 1963). Considered poor forage for livestock (Sedivec & Barker 1998). Rocky Mountain elk make a little use of the plants in spring but it is more important in summer (Kufeld 1973).

Propagation:
2 protocols in the Native Plant Network
Glacier National Park, Montana
Pullman WA Plant Materials Center

Other Propagation Information:
120 days of cold moist stratification with light resulted in highest germination. Germinates at low temperatures during stratification (Nauman 2002).
No pretreatment required (Link 1993).
Germinates without pretreatment. May take 1 month to germinate (Young & Young 1986).
Stratification does not increase germination (Sorenson & Holden 1974).
Alpine seed needs 9 months after-ripening (Kaye 1997).
Cold moist stratification increases germination (Greene & Curtis 1950).
Best growth obtained in greenhouse with day/night temps at least 20/10oC (McDonough 1969).
Highest germination at alternating day/night temperatures of 17/12oC (McDonough 1970).



Notes: Geum triflorum petals are yellow and nearly covered by the red sepals, but the plumed seed heads are pretty and the foliage is great. The foliage will stay green as long as there is moisture in the soil. Easy to grow from seed. Sow in spring. It can take up to four weeks to germinate, so keep the seedbed moist. Easier to grow in containers and then transplant to the garden. Flowers in late April and early May. Common names include prairie smoke, three-flowered geum or avens, old-man’s whiskers (Skinner et al 2005).
