Celestial Night is a striking modern floribunda rose celebrated for its rich, velvety plum-purple blooms—an uncommon colour in hardy landscape roses. The flowers are large, very full, and ruffled with a classic, old-fashioned form, often produced in clusters for a dramatic display. The deep green, glossy foliage enhances the intense bloom colour while offering improved disease resistance compared to many darker roses. This variety blooms continuously from late spring through fall and makes a bold statement in garden beds or as a feature shrub.
