Sabulina verna


Sabulina verna is a scarce species of flowering plant in the family Caryophyllaceae, known by the common names spring sandwort, leadwort, golden moss, or Irish moss. It is a small mat-forming, perennial herb. It was first described as Arenaria verna by Carl Linnaeus in 1767 and is known by several synonyms including Minuartia verna.
The small, 5-petalled flowers appear on short, downy stems from spring until late summer. The slender leaves have 3 veins.
It ranges across temperate Eurasia and northwestern Africa with a boreal-montane distribution. It is typically found on carboniferous limestone ground. It grows in short grassland, on exposed limestone pavement, on scree slopes and on metal-rich soils, including spoil heaps from lead mining.
