Dianthus chinensis 'Double Gaiety Mix': seeds

Dianthus chinensis, known in English as "Chinese pink" or "rainbow pink" and in French as œillet de Chine, is native to east Asia. The flowers are in various shades of pink or white, often bicoloured, with zigzag edges as if cut by pinking shears.

This is my first year growing pinks. I started them from seed on March 17 (inside, under lights) and yesterday I saw a pink had already sprouted!
