Thesium pyrenaicum
Meadow bastard toadflax (Thesium pyrenaicum) is a small perennial herb from western and central Europe that partly feeds on other plants' roots as a semiparasite. It is a wild meadow species, not a garden or houseplant, so it is rarely grown and care is mostly about leaving it in suitable grassland.
Thesium pyrenaicum is a species in the genus Thesium of the sandalwood family, Santalaceae. The genera and species of this family are usually semiparasites feeding on other plants. T. pyrenaicum or meadowflax is a perennial herb between 15 and 50 cm (5.9 and 19.7 in) high. It occurs in Western Europe. With standing stem(s) the leaves are lineal, with three veins, alternate, without stipules. The flowers, with 3-5 petals, are tube-shaped, and bloom in June and July. The petal tops roll in during the fruiting season. It has 5-9 stamen with distinct ovaries. The seeds are nutlike. The fruit is shorter than the flower.
