Polyantha Climber 'Margo Koster': Koster's Parisian Charm

Introduced in 1935 by Koster, 'Margo Koster' (also known as Parisian Rose, Sunbeam) is a polyantha climber that brings a touch of Parisian romance to walls and trellises. Its small, semi-double flowers open in a warm salmon-pink, fading to soft pink, produced in such abundance that they obscure the foliage at peak bloom.

Botanical Profile

The flexible canes reach 8-10 feet, making it ideal for training over arches or along fences. The foliage is small, dark green, and dense. As a polyantha, 'Margo Koster' inherits the class's signature traits: exceptional floriferousness, disease resistance, and a neat, twiggy habit. The name "Parisian Rose" evokes the cultivar's popularity in French gardens, where it cloaks walls in a veil of salmon-pink each summer. Nearly a century after its introduction, it remains a favorite for gardeners seeking a carefree climber with vintage charm.
