A particular site in our garden (USDA zone 4) has dry, sandy soil over heavy clay and gets full sun. There is excellent drainage due to the retaining wall on one side that has a drainage pipe situated below two feet below grade.
What are some good, small shrubs with the following characteristics that will grow well under the above conditions?
- preferably native to North America
- tolerates dry full sun conditions
- height of two to six feet, width of three feet
- flowers can occur in spring or summer
- berries or some fruit that hang on, red colour preferred
- excellent fall colour
- should not sucker, tolerate pruning if over 4 feet
What I've looked at so far is
- Aronia melanocarpa "Brilliantissima": However, I understand it suckers and can grow eight to ten feet wide.
- Euonomyus elatus compacta: In our area, good fall colour is not guaranteed with this cultivar.
- Ribes aureum: There is a dwarf white pine very closeby and as the Ribes is susceptible to white pine blister rust, this doesn't seem promising.
Does anyone have any other suggestions?
