The best white sweet pea at the moment, White Supreme has a restrained ruffled look that is elegant and sassy while harking back to its grandiflora origins. A pure, but not blindingly white flower can reach up to 6 cm across and you may get several on each long, sturdy stem. As a Spencer sweet pea the fragrance is not quite as strong as some of the old-fashioned varieties but the size of the flower and the fact that its stems will be straight more than make up for this! It has slightly grey-green foliage which looks pretty with the flowers. It can happily reach 2 m tall indicating its stamina and the number of flowers that you will proudly grow. One of the best sweetpeas you can buy.
It may appear obvious, but a white sweet pea 'goes with' all the other coloured sweet peas and is particularly effective against some of the flakes like America or Raspberry Ripple. Its excellent cutting flowers last well in a vase so for anyone thinking of growing sweet peas for a summer celebration of any sort, White Supreme should be on your short list at the very least. Growing sweet peas with Runner beans in a potager is a win-win for both plants because the scent of the sweet peas attracts many pollinators which will result in many more beans. Be prepared for a glut! Choose white flowering beans like White Lady or Czar for maximum effect.
White Supreme was raised by Bernard Jones and was introduced to the market by Boltons. It received its RHS AGM in 1994.
