Kingdom: Plantae

Phylum: Magnoliophyta -- flowering plants

Class: Magnoliopsida -- dicotyledons

Family: Rosales

Family: Rosaceae -- rose

Infraspecific taxa: P. glandulosa is highly variable species for which a large number of intraspecific taxa have been proposed.

Common Name: sticky cinquefoil

Species Code: POGL9

Origin: Native to dry to moist grasslands and forests from British Columbia to California and east to Montana and New Mexico.

Rare: no

Form: forb, highly variable, perennial from a branched caudex or from rhizomes; glandular overall; stems simple, more or less erect, 10-60 cm tall, often anthocyanous.

Mature height: 6-24 inches

Duration: perennial

Longevity: medium lifespan

Habitat Type: prairie, forest

Wetland Indicator Status: not listed

Leaves: basal leaves long petiolate, pinnately compound with 5-9 leaflets, the terminal leaflet largest; leaflets variable from flabellate, obovate, ovate or diamond-shaped, serrate or biserrate, glandular pubescent to nearly glabrous; cauline leaves alternate, few, reduced upward.

Flowers: borne in an open to compact cyme, branches spreading to erect; calyx glandular-hairy, rotate to bowl-shaped, the 5 segments 4-8 mm long (to 12 mm in fruit), lanceolate to ovate-oblong, with 5 shorter bracteoles alternating with the sepals; petals 5, deep yellow to almost white, spreading to erect, oval to obovate, 5-9 mm long; stamens usually 25 (to 40), pistils numerous, styles fusiform.

Flower color: yellow

Bloom: May, June, July

Fruit: achene, numerous, 1-1.3 mm long, ovoid, reddish brown.

Characteristics:
Drymocallis glandulosa in Piper & Beattie 1914.
Reproduces sexually by seed and vegetatively by rhizomes.
Potentilla as a genus is difficult taxonomically. The genus is often apomictic but also freely hybridizes, causing further complications.
2,969,000 seeds/lb (USDA NRCS PLANTS Database 2010).
3,378,000-4,429,000 seeds/lb (Hassell et al 1996).
Seed is stored in the seed bank (Reeves 2008).
n=7 (Hitchcock et al 1969, Baldwin et al 2004).
Flowers are perfect.
Native peoples used the plant medicinally (Parish et al 1996).
Fruit is an achene.
Rocky Mountain elk use the plants in summer and fall (Kufeld 1973).

Sun requirement: full sun to partial shade

Soil moisture: mesic

Precipitation: 8-35 inches (USDA NRCS PLANTS Database 2010).

Fire: Response may vary according to infraspecific taxa and site. Generally persists after fire and probably regrows from the caudex or rhizomes and from seed stored in the seed bank. Severe fires often reduce cover and frequency (Reeves 2008).

Sowing time: fall or very early spring

Transplant time: spring

Stratification: cold moist

Seed yield: medium

Seed harvest: medium difficulty

Seed first harvest: 2nd season

Seed cleaning: easy

Planting duration: moderate

Seed insect problem: none noted

Seed shatter: medium

Seed size: small

Seed harvest date: August

Seed comments: Holds seed well if there is no wind. When hand harvesting, hold the plants upright until they are in the bag.

Herbaria: Specimen data and digital resources from The Consortium of Pacific Northwest Herbaria

Keywords: native perennial upland forb

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

Other Propagation Information:
1-3 weeks cold moist stratification at 3^oC, then germinate at 20-30^oC with light (Chirco & Turner 1986).
No treatment needed for fresh seed. Seed which has been stored needs cold moist stratification (Mirov & Kraebel 1939).
Best growth was obtained in a greenhouse with alternating day/night temperatures of at least 20/10^oC (McDonough 1969).
Without pretreatment very low germination occurred at 30/20^oC alternating day/night temperatures with alternating light. No germination occurred at any other light and temperature regimes without pretreatment. 3 weeks cold moist stratification, then alternating 30/20^oC temperatures with alternating light, or 15^oC in the dark resulted in 72% germ (Maguire and Overland 1959).
Reproduces sexually by seed and vegetatively by rhizomes.

Notes: Should be a good landscape plant on mesic sites with plenty of sun.
