Hieracium radyrense (Pugsley) P.D. Sell & C. West
|
Radyr hawkweed, also known by its scientific name Hieracium radyrense, is a super rare plant. It's an endemic species, which means it only grows in one small place: Radyr in south Wales, UK. You won't find it anywhere else in the world!
Scientists first discovered this plant in 1907. It was officially named a species in 1955. Radyr hawkweed belongs to a group of plants called Hieracium, often known as hawkweeds. It's incredibly rare. Surveys done between 1998 and 2004 found only about 25 plants still alive.
What Makes Radyr Hawkweed Special?
Radyr hawkweed is a perennial plant. This means it lives for many years and can flower more than once in its lifetime. It usually blooms in late spring to early summer, from late May to early June or July.
The few plants found in a place called Danybryn in Radyr grew on a grassy bank and a lawn. They liked to grow where there was some shade from trees and shrubs.
