Description

Penstemon Nova® ‘Twilight’ is a particularly compact and floriferous variety, ideal for bringing a touch of freshness and lightness to the garden. From June onwards, it produces a profusion of blue-violet flowers, borne in upright clusters above well-structured vegetation. This generous flowering continues until October in sunny borders, flower beds, and containers. It is a lovely perennial plant for creating natural, colourful scenes.

Penstemon NOVA® ‘Twilight’, from the Scrophulariaceae family, is a horticultural selection characterised by its dense, upright and compact tufted habit. This cultivar is distinguished by its clusters of tubular blue-violet flowers that seem to float above the foliage like real clouds. Its flower spikes are produced early and continuously from the beginning of summer until the first frosts. The medium to small flowers are particularly attractive to bees, butterflies and hummingbirds. This fast-growing penstemon reaches about 35cm in all directions. The medium green foliage consists of narrow, linear leaves regularly arranged on sturdy stems; this vegetation is deciduous, drying up in winter. Classified as hardy in USDA zones 7 to 9 (down to –15 °C at peak), ‘Twilight’ prefers full sun in well-drained soil and requires moderate watering.

Penstemon Nova® ‘Twilight’ is perfect for creating light, airy compositions. Its soft and luminous blue-violet flowers work well in a sunny border, a gravel garden, or a pot on the patio. In the garden, it can be planted with groundcover roses and woodland sages, for example. You can also combine it with Helichrysum ‘Korma’ with its silver tones, Achillea millefolium ‘Terracotta’, the dark spikes of Pennisetum ‘Black Beauty’ or the light flowering of Gaura ‘Whirling Butterflies’.

Planting and care

Penstemon Nova® ‘Twilight’ is best planted in spring or early autumn, in a light, well-drained soil, even slightly stony. In the open ground, choose a sunny position and space the plants about 30 to 35cm apart to allow them to develop well. Regular watering after planting encourages rooting, but the plant quickly becomes tolerant of moderate drought. To avoid excess moisture, especially in winter, it is advisable to apply a gravel mulch at the plant's collar. 
Plant it in a container at least 15 to 20cm in diameter, with draining substrate (potting mix lightened with sand or pumice). Water moderately during dry periods, without ever waterlogging the substrate. Hardy down to -15°C at its peak, this penstemon dislikes very wet winters and proves less hardy when grown in a pot.
