  • World Exclusive

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").

Teasel

Dipsacus fullonum, Dipsacus sylvestris, Wildflower

Teasels are an excellent architectural plant for the back of garden borders or in wildlife gardens where they will self-seed freely for a continual display. Dried teasel flowers also make an attractive and textural addition to cut flower arrangements. Height: 1.5m (5’). Spread: 45cm (18"). More info
