Common Teasel Overview
Dipsacus fullonum is a biennial species commonly known as Common Teasel, Wild Teasel or Fuller's Teasel. Typically grows to a height of around 2m. Produces bright green leaves which are joined to the stems at the base, forming a cup-like depression that gathers water, similar to pitcher plants. Flowers are small and blue-purple in colour, they measure around 6cm in length and are arranged on bristly flowerheads. The flowers lead onto attractive cone-shaped seedheads which persist into winter. They provide food to bird species, the European goldfinch is particularly fond of them! This species can be problematic, it is considered a noxious weed in certain locations such as New Zealand, plant with care! It can displace other plants and form large monocultures in favourable climates. Scientific evidence has shown that this species is capable of gleaning nutrition from insects caught in the leaves, studies report a 30% increase in seed set and the seed mass to biomass ratio in plants fed dead flies, thus this is termed a carnivorous species. This species is part of the Royal Horticultural Society “Plants for Pollinators” initiative to showcase plants which support pollinator populations by providing ample amounts of nectar and/ or pollen. A great choice for encouraging pollinating insect wildlife into your garden!
