Collection: Penstemon barbatus Twizzle

Twizzle is a first-year-flowering Penstemon series consisting of five colours. All have a natural and elegant plant habit and an excellent garden performance. The plants have strong upright stems and long airy spikes with tubular flowers. Twizzle adds height and elegance to annual and perennial borders and can be used in various creative landscaping combinations. This Penstemon series is pollinator friendly: it attracts many kinds of bees and hummingbirds. Well established plants in the garden are fairly drought tolerant and winter hardy. Growers can grow Twizzle as a cool crop and also outside, for a long sales season. When started from an autumn 
sowing the plants will flower in spring and early summer; the plants will bloom from a spring sowing in summer and late summer without vernalisation.
