Evergreen clematis are invaluable garden climbers and at this time of year Clematis armandii, in its various pink- and white-flowered forms is really spectacular.

I’ve been looking at the plant sales areas at garden centres around Britain over the last two or three weeks and one plant I especially noticed was a new form of this excellent plant – ‘Enham Star’. Discovered in the horticulture division of Enham, a national disability charity, the flowers are white with a slight pink blush and ‘Enham Star’ is said to be unusually prolific – and it certainly looks that way from the large plants I saw on sale. Look out for it in the new RHS PlantFinder, out next month.

Oddly, though, go to the Enham website and there’s no mention of the clematis at all.
