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.
Open sheet →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.
