Shrub (Bédard, United States, 2009).
Yes, we’re having fun with words on this name. It’s a ‘party’ because of the big old-fashioned bright pink blooms that arrive in showy clusters. It’s ‘hardy’ because it was bred in Canada & has proven to be perfectly adapted for harsh winters. Party Hardy survives without winter protection in zone 3. The shrubby full plant keeps its clean green foliage to the ground, growing like mad as a result. It’ll stand head & shoulder above the other roses in very cold winter climates…actually preferring those conditions. At its best in the coldest climates.
