Parentucellia viscosa Yellow Bartsia
This is a semi-parasitic plant which invades the roots of other plants to gain nutrients. It has been introduced to both north America and Australia where it can be invasive. The European plants look very similar to those found in southern England which should not perhaps be surprising as they are the same species but often European plants can look markedly different in habit and colour from the ones we see in more temperate northern climates of the British Isles.
