Pinus pinaster is a commonly grown tree in western Europe, and its value has been recognised in the form of an Award of Garden Merit by the Royal Horticultural Society. It is particularly successful on sandy soils, and develops from a gawky adolescence into a handsome older tree. It is probable that individuals in cultivation are principally subsp. pinaster, and equally probable that they are not distinguishable with any degree of certainty. If future collections are made in the wild, however, the locality and varietal attribution of the population(s) should be retained with the trees. It is less likely that subsp. renoui will be found in general cultivation, but there is a specimen at Benmore, accessioned in 1976 (from a collection made by Sendergaard in Morocco), and there are several trees at Kew of similar age.
