Poppy 'Plum Pudding'

Papaver orientale, Oriental Poppy

  • NEW in 2013
  • World Exclusive
  • Best in class for oriental poppies
  • T&M's own breeding
From T&M’s own breeding programme comes this superb Oriental poppy. Beautiful tissue-like blooms in a rich shade of plum-pink appear from June, and often give a second display later in the summer. The strong stems and non-fading flowers are longer lasting than most varieties, making this a significant improvement on the popular variety ‘Patty’s Plum’. By late summer Poppy ‘Plum Pudding’ produces attractive seed heads that make an eye catching feature in wildlife or cottage garden borders. Height: 75cm (30"). Spread: 60cm (24").
