|[ Silver Buffaloberry (Shepherdia argentea) | Posted on August 13, 2020 ]
I am always excited to discover an ornamental North American native plant, in this case a shrub, Shepherdia argentea, which is cold hardy, drought tolerant, and prefers fine textured soils. Its native range extends from the Canadian provinces of Manitoba, Saskatchewan and Alberta thru parts of Minnesota, the Dakotas, and Montana south to New Mexico and west to California at elevations to 7,500 feet. It's hardy to at least -50°F (-45.6°C). It's drought tolerant with minimum precipitation requirements of 12 – 14 inches per year and has moderate alkali (high pH) and salt-tolerance. Although it would not perform great in heavy clay, Silver Buffaloberry does actually prefer fine textured to coarser textured soils, as long as they are reasonably free-draining (like silt and clay loams).

Like many other plants with sticky leaf surfaces, sticky geranium is protocarnivorous; it is able to dissolve insects that become trapped on its leaf surface and absorb the nitrogen derived from this protein. This characteristic helps G. viscosissimum survive and thrive in nutrient-poor environments.
