Common Toadflax (Linaria Vulgaris)


The common toadflax, is also known as yellow toadflax, the chilling ‘dead men’s bones’, and the descriptive, ‘butter and eggs’. The Latin name for this species of toadflax is Linaria vulgaris, with Linaria simply meaning toadflax, and vulgaris translating as common.

It is a wild perennial herb which is similar in appearance to the garden snapdragon, has a short, creeping root system, and several, erect and slender stems, reaching up to around a metre in height. These stems are rarely branched, instead featuring numerous long, narrow leaves, of a pale blue-green colouration, generally 2-6cm in length, and 1-5mm wide.

What Does Toadflax Look Like?

The yellow wildflowers of the common toadflax sit proudly atop the upright stems, with vibrant orange lower lips. These clustered flowers are normally between 2.5 and 3.5cm long and are almost always closed, with only strong insects, such as bumblebees able to pry their way inside. Above these flowers sit the fruit, a globose capsule of numerous seeds, approximately 5-11mm in length and half as broad. 

The common toadflax adds real beauty to your Meadowmat.

The delicate-looking, but hardy common toadflax is present year-round in some form, but flowers from late June until October and the first signs of frost. This gives a splash of yellow wildflowers to your Meadowmat for over one-third of the year.
