Treasured for its eye-poppingly vivid cobalt-blue flowers, Ceratostigma plumbaginoides 'Gentian Blue' is a low, spreading herbaceous perennial that makes fabulous colourful groundcover or merits a prominent position toward the front of a sunny border. Red-tinted stems bear clusters of the intense royal blue flowers from August to October. As autumn progresses, the green summer foliage turns to vivid shades of burnt orange and red, bringing a welcome splash of colour to fading borders. Tolerant of a wide range of soils, this blue-flowered leadwort is a great low-maintenance perennial for covering large areas, providing months of colour and interest throughout late summer and autumn. Height: 30cm (12in). Spread: 45cm (18in).

Thompson & Morgan strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3
