Ranch elderberry is among the most cold hardy of black elderberry plants. It can tolerate climates as cold as USDA zone 3. It grows to a shorter stature than most other elderberries, making it a great choice for where space is limited. Ranch grows in a wide variety of soil types, and is even considered to be the most tolerant of poor, non-fertile soils.
