Vitis ‘Merlot’ is a vigorous deciduous grapevine grown for its ability to produce dark, richly coloured wine grapes in warm, sunny conditions. The plant forms large, deeply lobed leaves that create dense coverage when trained against walls or supports, offering both ornamental value and shade. When given sufficient heat and light, it develops clusters of deep blue-black grapes with a rich flavour profile. Best suited to sheltered outdoor positions or unheated greenhouses in the UK, ‘Merlot’ is an excellent choice for gardeners interested in growing classic wine grapes while also enjoying the architectural presence of a traditional climbing vine.
