The semi-evergreen foliage provides a degree of winter structure, and many varieties are surprisingly hardy once established, particularly if given a warm, sheltered position with excellent drainage. They are ideal companions for late-season bulbs, grasses, and other late-flowering perennials in a mixed border.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOther benefits:\u003c\/b\u003e exceptionally long flowering season, wide colour range, semi-evergreen, good for cutting, suitable for containers\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWildlife attraction:\u003c\/b\u003e bees, bumblebees, and hoverflies are regularly attracted to the tubular flowers throughout summer and autumn\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHeight \u0026amp; spread (approx.) at 10 years:\u003c\/b\u003e 0.6–0.9m x 0.5m depending on variety\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePosition:\u003c\/b\u003e full sun; sheltered, well-drained border; excellent against a warm wall\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSoil pH:\u003c\/b\u003e neutral to slightly alkaline; well-drained, sandy and chalky soils; avoid heavy, wet conditions\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMoisture:\u003c\/b\u003e low to moderate; drought tolerant once established; excellent drainage essential for winter survival\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWinter hardiness:\u003c\/b\u003e most varieties hardy to approximately -15°C with good drainage; mulch the crown in colder gardens\u003c\/p\u003e","brand":"Cedar Nursery - Plants and Outdoor Living","offers":[{"title":"2 litre","offer_id":56986873037178,"sku":"008982","price":10.0,"currency_code":"GBP","in_stock":false}],"url":"https:\/\/www.landscaping.co.uk\/products\/penstemon-varieties","provider":"Cedar Nursery - Plants and Outdoor Living","version":"1.0","type":"link"}
