I brought several hen and chick from my grandmother's WI garden to CO when I moved with my DH in 2009. These plain little plants are very important to me. I have a great little rock garden along the side of my house and have expanded my collection with some eye catching additions from the botanic garden sale each year. Today, even after explaining thoroughly, my carefully tended rock garden had work boots treading over the hens and chicks for hours. Are they salvageable? Is there something I can do to help them? my grandmother's house was razed and paved into parking lot in 2011, I can never retrieve more plants.
