Jim Naylor.  Personal Favourites
My choice is 'Hakuun' (which means White Cloud in Japanese). A very versatile rose, 'Hakuun' is a low-growing floribunda (DCF) introduced by Poulsen in 1962. It bears masses of rounded, semi-double blooms in closely packed short stemmed sprays.  In early stages, it is a creamy yellow, paling to white with pink flecks,  the scent is light. It continues to flower throughout the summer into the autumn.  I find it especially useful to edge a border, as in the bed outside the library at Rose Society, HQ or for any small space where a cool colour is desired. It also does particularly well under glass, producing large clusters very easily and in time for April/May spring shows.
