About
Astrantia carniolica is a perennial herb that grows in upright clumps, reaching approximately 45 cm tall. It features finely divided, mid-green foliage that adds texture to the garden. In late June, branched stems emerge, showcasing compact clusters of soft, fluted white blooms encircled by green-tipped bracts. If the plant is pruned after the initial flowering, a second wave of blooms may appear in late summer.
