Jookie, they look absolutely beautiful in the window inside their really nice window box (pat on back for DH!). I would just keep a close on any one of them for maladjustment to new environment (too much light, not enough watering, etc) I think you are getting it that succulents are sort of divided into hardy (ie semps) and tender (jade, pachyveria, kalachoe, eche ). And that this division calls for tweaking of requirements. Time and experience will help you with all that. Thanks for sharing your plant experiences with us.
Good luck and don't forget to indulge in our Semp Week with us. Look at our tips and articles for much, much information about planting, pests, history, container choices, and other important info and ideas!!!
