Seedling
tree of the introduced species, Amur Cherry. Goldspur is a dwarf
selection discovered in Saskatoon, SK. by Dr. Philip Ronald.
Hardiness:
Zone 2 (Canadian and USDA)
Growth
Rate: Moderate;
very short internodes.
Description:
A
unique selection of Amur Cherry with dense, peach-like foliage.
Mature plants of Goldspur® reach
about 15 feet (5 m) in height with a 9 foot (3 m) spread; about
half of that for typical Prunus
maackii seedlings.
Creamy white spring flowers produce compact racemes of tiny black
fruit in mid- summer.
Goldspur’s golden exfoliating bark is a desirable winter
feature.
Landscape
Value: Goldspur
is a very distinctive tree with its dwarf growth habit and dense,
dark-green foliage. Goldspur has shorter racemes of white flowers
than Prunus maackii, followed by tiny black fruit. As
one of the first clones of Amur Cherry, it offers uniformity in
this underused species. An excellent small tree for the landscape.
Resistant to black knot fungal disease.
Propagation: Goldspur® is being propagated in tissue culture by Agriforest
Biotechnology. Goldspur can also be readily
propagated by softwood cuttings.
