Yukon Belle Pyracantha is a hardy, thorny evergreen to semi-evergreen shrub that's especially valued for its cold tolerance and reliable mid-winter berry display. It's a cultivar of narrowleaf firethorn, introduced as one of the toughest options for colder climates, with abundant white spring flowers followed by masses of bright orange (sometimes described as red-orange or brilliant orange) berries that persist through winter and attract birds. This variety is often highlighted for its resilience — it's more cold-hardy than many pyracanthas (including Mohave) and shows good resistance to diseases like fire blight in many sources.
