|Family Scientific Name:
|Family Common Name:
||Cornus sericea L. sericea L.
||Cornus stolonifera Michx.
||Red stem dogwood
||Aspen Forest, Saint Mary, 1250 m elev. Glacier National Park, Glacier Co., MT.
||C. sericea ssp. sericea occurs from Alaska to Newfoundland, south through the Rockies to Mexico; also south through the Cascades and Sierras to southern California and Nevada; further east in Missouri and Pennsylvania. It is found in mixed, open coniferous and aspen forests, riparian zones, wetlands, flood plains, and is invasive of wet meadows.
||3 L (1 gal) containers
|Time To Grow:
||Stock Type: Container cutting
Height: 30 cm
Caliper: .5 to 1 cm
Root System: firm plug in 3L (1 gallon) containers.
||Vegetative Propagation Method: Pre-Rooting or Direct Sticking
Type of Cutting: Spring hardwood and summer softwood stem cuttings.
Hardwood cuttings are collected in April andearly May before budbreak.
Softwood cuttings are collected in June and July before or after flowering.
Cuttings are collected from healthy field plants. Cuttings average 20 to 30 cm in length and .5 to 1 cm in caliper.
||Cuttings are kept moist and under refrigeration prior to pre treatment.
||Cutting Treatments: Cuttings were cut into 20 to 30 cm lengths, with the base recut and 1/3 of leaves or buds removed. Cuttings were placed in a 2 minute fungicide bath to remove surface pathogens.
Softwood cuttings were treated with 2000 ppm liquid Quick Dip IBA, and stuck in an intermittent mist bed with at least 2 nodes below the surface of the rooting medium.
Hardwood cuttings were treated with 2,000 ppm liquid IBA and directly stuck into 3L (1 gallon) containers filled with medium.
Rooting %: 80 to 95% in 4 to 6 weeks for Softwood (Pre-Rooting)Cuttings.
Rooting %: 65 to 88% in 8 weeks for Hardwood (Direct Sticking)Cuttings.
High rooting percentages are easily obtained with both softwood and hardwood cuttings treated with 2000 ppm IBA rooting hormone.
This species roots so readily that dormant hardwood cuttings (direct sticking in containers) with no IBA treatment had a rooting percent range of 65 to 80%. There are latent root initials present in the stems.
|Growing Area Preparation/
Annual Practices for Perennial Crops:
The outdoor mistbed has automatic intermittent mist that is applied at 6 second intervals every 6 minutes. Too frequent misting will result in leaf and stem rot. Bottom heat is maintained at 21C with heating cables buried 12 cm beneath rooting medium. Rooting medium is 50% perlite and 50% sand. Mistbed is covered with shadecloth during rooting. After cuttings have rooted, they are moved to the shadehouse for 4 weeks. Later, they are moved to full sun exposure in the outdoor nursery.
||Time to Transplant: 8 weeks.
Softwoood cuttings that were prerooted were lifted out of mistbed after adequete root systems were formed.
Roots generate from the nodes below the surface of the rooting medium.
|Length of Establishment Phase:
|Active Growth Phase:
||After cuttings were lifted from the mistbed, they were potted into 3L containers.
Growing medium used is 6:1:1 milled sphagnum peat, perlite, and vermiculite with Osmocote controlled release fertilizer (13N:13P2O5:13K2O; 8 to 9 month release rate at 21C) and Micromax fertilizer (12%S, 0.1%B, 0.5%Cu, 12%Fe, 2.5%Mn, 0.05%Mo, 1%Zn) at the rate of 5 grams of Osmocote and 2 grams of Micromax per container.
Cuttings were irrigated after potting and placed in the shadehouse for 4 weeks. After establishment in the shadehouse, plants were moved to full sun exposure in the outdoor nursery.
|Length of Active Growth Phase:
||Plants are fertilized with 10-20-20 liquid NPK at 200 ppm during August and September. Plants were given one final irrigation prior to winterization.
|Length of Hardening Phase:
|Harvesting, Storage and Shipping:
||Total Time to Harvest: 1 year from cuttings in 3L (1 gallon) containers.
Harvest Date: June or September
Storage Conditions: Overwinter in outdoor nursery under insulating foam and snow.
|Length of Storage:

Outplanting Site: Lake McDonald, Glacier National Park, MT.
Outplanting Date: Spring or fall
Outplanting Survival at 5 years: 86%
