Penstemon scrophulariaceae 'Cha Cha Pink'

Cha Cha Pink Penstemon

Botanical Name: Penstemon ‘Cha Cha Pink’
Family: Scrophulariaceae
Origin: North America (garden cultivar selection)
Plant Type: Evergreen to semi-evergreen perennial

Overview

A vibrant, long-flowering Penstemon perfectly suited to Adelaide’s Mediterranean climate, Penstemon ‘Cha Cha Pink’ produces masses of bright pink tubular blooms with softer blush and rose tones, creating a lively display from late spring through autumn. Compact, upright and bushy, it is ideal for mixed borders, cottage gardens, waterwise landscapes and pots. The foliage is mid-green and lightly glossy, sometimes developing soft bronze or reddish tints in cold or very dry weather. While not considered fragrant, the flowers may have a faint sweet note when closely inspected. Exceptionally heat- and drought-tolerant once established, it thrives in SA’s warm, dry summers provided the soil is free-draining.
