How to tell it
A well-marked basal rosette of oval to nearly round leaves, three-veined from the base and hairy beneath, lying flat on the ground. Slender branched stems rise from the rosette with yellow flowers two to three centimetres, their petals falling the same day. The rosette persists all year.
What it is confused with
Spotted rock rose
Tuberaria guttata
Spotted rock rose is annual, with smaller flowers marked by a dark blotch at each petal base, and its rosette dries in summer; alcária is perennial, its flowers unblotched and its rosette persists. Neither is dangerous.
What it is for
No use
The persistent rosette is useful for identifying the plant out of flowering season, which almost no rock rose allows.
Where it occurs
Each square is an area with recorded observations of this plant. The lighter background is the set of areas where any of the entries has been observed, and serves as a reference. Note what this is not: it is not where the plant lives, it is where people record it, so trails and towns always look fuller than the mountains. Data from GBIF.
