A remarkably tough and tolerant plant, silver buffaloberry has silvery gray-green foliage and red berries that are sour but edible, often used in jam. An upright but rounded deciduous shrub, it is native to western North America.
The medium to light green elongated leaves are covered in tiny white hairs, causing variation in some plants to have a gray-green or fully silvery coloration. Plants are dioecious - male and female flowers, both yellow-green and tiny, are borne upon separate shrubs. The female shrub, if pollinated, produces rounded clusters of orange-red to scarlet fruits along the branches. They are edible but sour to the tastebuds, birds eat them anyways. There is no decorative fall foliage coloration before leaf drop.
Place silver buffaloberry in full sun exposures in an average, fertile soil that is well-draining and not acidic in pH. It is tolerant of drier soils, wind, bitter cold and salt, adding to its potential positive uses in landscapes. It can be a windbreak, screen or accent shrub, particularly if contrasted by dark green colored shrubs and trees in the vicinity. (source: learn2grow.com)

|Germination||1. Soak seeds for a couple of hours in a warm water.|
2. Cold/moist stratify for 30 days in dampened peat or sand, in a plastic box or bag at 4°C or 5°C in a refrigerator. The seeds should not be frozen or in a wet medium.
3. Sow on the surface of moist soil, tamp the soil. Keep in bright and warm place for germination.
Prick out the seedlings into individual pots once they are large enough to handle. If sufficient growth is made it will be possible to plant them out in the summer, otherwise grow them on in a cold frame for their first winter and plant them out in the following spring or early summer. Cuttings of half-ripe wood, July/August in a frame sometimes work.
