Small toadflax has found space for itself in even the barest of places: between urban paving stones and holes in the asphalt, cracks in the concrete and gravel heaps in railway yards. It is native to places south of Finland in Europe and south-west Asia. It has come to us along with human activity in ballast soil, freight, soldiers’ provisions and escapes from experiments in botanic gardens. It is still relatively rare, but it seems to be enlarging its habitat through e.g. the railway network.
Lesser snapdragon, (also called weasel’s snout, Misopates orontium) is a look-like of small toadflax and can be found growing wild in Finland as a casual alien. Also snapdragon (Antirrhinum majus) can be found in Finnish gardens and maybe outside, too. Small toadflax is in a genus of its own but is close to genus Linaria, which it has formerly been a member of. It differs from the species that grow in Finland most noticeably with regards to its modest size.
