Perennial & Biennial Seeds


Biennials live for 2 years, whereas perennials live for longer. As a general rule, biennial and perennial seeds should be sown in spring, but some can be sown in autumn as well. Many varieties will self-seed after flowering, giving you even more plants!

Sarracenia species 'New Hybrids Mixed'

Pitcher Plant

  • New in 2014
Seemingly innocent, the leaves of the pitcher plant have evolved into water-filled funnels that hide a sinister purpose. These intriguing carnivorous plants devour insects to improve their diet and counter poor nitrogen levels in the soils of their natural habitats. Lured by the promise of sweet nectar-like secretions on the lip of each pitcher, their victims are met by a slippery footing and tumble to a watery death deep within each funnel. Endlessly fascinating, Sarracenia species 'New Hybrids Mixed' make a captivating talking point for the greenhouse, conservatory or a windowsill indoors. Plants will be mature enough to catch insects after 2 - 3 years. Height: 30cm (12"). Spread: 20cm (8").
