About Starry hawkweed
Hieracium substellatum, known as Épervière in French, is a perennial herbaceous plant belonging to the Asteraceae family. It is characterized by its basal rosettes of star-shaped leaves (hence its name 'substellatum') and its delicate yellow flowers, resembling those of a dandelion. It is an excellent choice for rock gardens, path edges, or as a wild plant in natural meadows, adding a rustic and natural touch.
Care tips
It prefers sunny or semi-shady locations and tolerates drought well once established, although occasional watering during dry periods will promote flowering. It adapts to a wide range of soils, as long as they are well-drained, including poor and stony ones. Avoid overwatering, as it is susceptible to root rot in consistently moist conditions. It does not require regular fertilization and, in fact, thrives in nutrient-poor soils.
