Description

Masses of long, white, candle-like flower spikes,up to 15cm long, cover this bushy compact variety through late summer. The flowers of Clethra alnifolia ‘Sixteen Candles’ are sweetly clove-scented and long-lasting, luring a wealth of beneficial pollinators. They are especially popular with butterflies. This bushy, rounded, suckering shrub is covered in glossy, toothed leaves which often turn strong shades of yellow in the autumn. A lovely choice for a shady, lime-free border where it will flower abundantly. Height and Spread: 1m (39in).

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

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
