Subsequently many hybrids were developed in Europe.įieldwork during the 20th century brought the total number of species known to over 250. During this time, seeds began to be offered for sale in Europe, the earliest known dating from 1813, with John Fraser offering four species in London, followed by Flanagan & Nutting offering nine species in their 1835 cataloge. The period of 1810 to 1850 increased the number of known species from 4 to 63, as expeditions traveled through Mexico and the western United States, followed by another 100 up to 1900. Mitchell's work was reprinted in 1769, continuing with his original spelling, and this was ultimately accepted as the official form, although Pentstemon continued in use into the 20th century.Īlthough several more species were found in the 18th century, they continued to be classified in Chelone until about the 1820s. Linnaeus then included it in his 1753 publication, as Chelone pentstemon, altering the spelling to better correspond to the notion that the name referred to the unusual fifth stamen (The Greek word 'penta' meaning five). John Mitchell published the first scientific description in 1748 although he only named it as Penstemon, we can identify it as P. It can be found on rocky slopes and open woodlands from Utah and Colorado to Arizona, Texas and Mexico. Penstemon barbatus is native to the western United States.

Spring sowing will obviously give them a full season of growth, for flowering July to September. Sowing: Sow between February and April for first year flowers, or sow in September for early summer flowering the next year.

Penstemon barbatus ‘Twizzle Scarlet’ has been awarded the Fleuroselect Gold Medal for striking colour, plant habit, and all round flowering performance.A long-lived perennial, the plants are strong, trouble-free and quite drought-tolerant once established in the garden. Let it self-sow in your garden or collect the seeds in autumn and plant them wherever you want an injection of summer-long colour.

The Twizzle series is open pollinated, this means the plant will come true from seed. The plants are vigorous and low maintenance and will perform best in full sun and well-drained soil. Sow seeds in autumn for earlier spring blooms or start indoors in late winter for first-year summer blooms. Twizzle can be used to add height and high-impact colour to containers and annual/perennial borders. The blooms are crammed tightly along the lengthy stems, making this beauty a magnet for pollinators. Plants form a low clump of green foliage, with upright spikes appearing in mid-summer.

The plants bloom profusely with 3 to 4cm (1 to 1½in) tubular flowers on long slender stalks that grow 70 to 80cm (28 to 32in) tall. This year, Twizzle White and Twizzle Blue have been added to the series.īoasting half the foliage of older varieties and twice the length of flowering stem, Penstemon ‘Twizzle’ series brings you longer, more elegant blooming wands without sacrificing plant size. This award-winning flowering series originally offered three colour varieties, Twizzle Coral, Twizzle Purple and Twizzle Scarlet. The plants have an upright plant habit and give superb flowering performance from mid to late summer. This first year flowering perennial boasts taller flower stems than the existing varieties on the market while preserving the natural elegance of Penstemon barbatus. Penstemon barbatus ‘Twizzle’ adds a graceful twist to the garden. We tend to think of penstemons as large-flowered and blowsy, but the first of a new series derived from the American native Penstemon barbatus is rather different.
