Temperatures can be unpredictable. If your plants are being shipped to a cold climate, it is the responsibility of customers residing in areas subject to freezing weather to purchase one of our low cost Heat Packs and add it to your order. Heat pack purchases can be chosen when you add the succulent to your cart. While heat packs do not guarantee protection from frost, they will help prevent damage from occurring. Uniheat shipping warmers are the first designed especially for small pets, tropical plants and other temperature-sensitive products.
