We do our best to send out “hardened off” plants. However, some things are susceptible to damage when the temperatures get below 30°F. The following is a list of those plants which should be covered when the forecast is calling for cold. You can cover with a sheet, light landscape cloth, frost blanket, or bring them into a sheltered location.
Amsonia, Anemone (japonica types), Aruncus, Asparagus, Astilbe, Digitalis, Eupatorium, Ferns, Hibiscus, Hosta, Lavandula, Parthenocissus, Perovskia, Platycodon, Rodgersia and Warm Season Grasses: Miscanthus, Schizacharium, Pennisetum and Sporobolus.
