Overview: An introduced shrub growing to six meters high. The 'Ross' seed strain was selected for its outstanding cold and drought hardiness. First introduced to Canada in the late 1800s, it became the number one species in western Canada planted for soil erosion control. It is a legume and fixes nitrogen. The 'Ross' seed strain is named in honour of Norman MacKenzie Ross who pioneered shelterbelt tree planting in the Canadian Prairies.
Fruit: Dark brown linear pods 3 to 5 cm long. About 40 seeds per gram.

Sowing instructions: Sow 2 cm deep, 50 seeds/meter; Greenhouse - sow 3 seeds per cell.
Growing conditions: Best growth on well-drained light and medium-textured soils. Fertilization is not required. Will tolerate slightly saline conditions.
Excellent for farm or field shelterbelts or landscape hedges where a tough hardy plant is needed. 'Ross' caragana is extremely drought tolerant that forms a dense hedge useful as a windbreak for snow and wind management.
