Penstemon 'Pink Cloud'

Pink Cloud Penstemon

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

Overview

Perfectly suited to Adelaide’s Mediterranean climate, Penstemon ‘Pink Cloud’ is a soft, romantic cultivar producing masses of pale to mid-pink tubular flowers that appear to float above the foliage from late spring through autumn. The blooms are lighter and airier in tone than many penstemons, creating a gentle, cottage-style effect that works beautifully in mixed borders, pollinator gardens and waterwise landscapes. Upright yet compact, it thrives in full sun and free-draining soils, handling heat, wind and dry conditions with ease once established. The mid-green foliage is neat and lightly glossy, and may develop subtle bronze or reddish tints during cool winters or extended dry spells. Flowers are not strongly fragrant, though a faint sweetness may be noticed up close.

Where It Works Best

• Sunlight: Full sun for strongest flowering; tolerates light part shade with reduced bloom
