You can care for your succulents better than you do if you aren't familiar with their needs. I have many of these plants, which I keep in various planters. They are easy to care for and grow well. Too much sunlight and improper watering can kill succulent plants. Larger succulents can withstand longer watering periods than smaller succulents. These succulents are hardy and can withstand freezing. Protect the Echeveria Prolifica from frost. Echeveria Perle vom Nurnberg- This Echeveria has fleshy leaves that can sometimes turn from blue-green into purple or red.
