Lathyrus vernus is a most useful and beautiful perennial; it remains in a tight clump, emerges in early spring and then gets covered in myriads of pea-like flowers. It will grow well in full sun, also in part-shaded positions, in which case it will remain in flower for a longer period of time.
One of those plants that the more you have the better.
Germination: sow in the fall or early spring; seeds require scarification (sand papering works just fine). Seeds from a pink flowered specimen, it may be or not ‘Alboroseus’, so I don’t know if the seedling will be true to colour. Either way, a beautiful plant in any colour.
