Alpine bastard-toadflax is a semi-parasitic alpine perennial that attaches to the roots of neighboring plants for nutrients, making it a challenging specialist plant to cultivate. It prefers well-drained, calcareous soils in full sun to partial shade and requires a suitable host plant nearby to thrive. Best suited for experienced growers interested in alpine or botanical gardens.
