traditionally grew on grassy banks and lawns, often in shade. It was no longer found at the original locality of Radyr Quarry where examples were last seen in 1985. At Bridgend, six possible plants of the Radyr genus were found on an old garden wall, but confirmation of identification is still awaited. Neither the species nor the sites have any current legal protection, and it could be under significant threat of survival in the long term from inappropriate gardening or care. Seed samples of the Radyr hawkweed have been provided to the Millennium Seed Bank, the international conservation project coordinated by the Royal Botanic Gardens, Kew, and plants are being carefully cultivated. The plant normally flowers between May and early July and Radyr residents are urged by botanists to be on the look out for further examples of the endangered species while walking in the area.
