Hen-and-Chicks Hen-and-chicks is a tough succulent groundcover that slowly spreads by producing offsets. It's well suited for growing in trough gardens because of its shallow root system. It also grows well in cracks and crevices in rocks or as part of a green roof garden. Pink or yellow flower stalks rise to a foot above the foliage. These are hardy & easy to grow and I have tons of them.
