Yes, I was thinking, this looks something like an Epiphyllum, but I don't think it is. The flowers are much smaller, and the name 'Mistletoe Cactus' rings a bell somewhere...It is Disocactus ramulosus. The fruits somewhat resemble those of a true Mistletoe of Christmas fame...

Sirron, I have what looks exactly like your #2. Mine came with a tag which says Sedum lineare. I assume that should be Sedum lineare 'Variegatum'. http://www.plantdelights.com/Sedum-lineare-Variegatum-Perennial-O-no-mannengusa/productinfo/241/ This photo isn't quite as close to yours or mine: http://www.smgrowers.com/products/plants/plantdisplay.asp?plant_id=3339

Kara, Currently I leave both the plants at my east-facing window sill at which sunlight is available for around 8am to 10am. And I plan to increase the sunlight exposure by an hour a week. Hopefully, they can enjoy themselves =) P/s: I live in the southern region in which the weather is still sunny and not quite humid at this time of year ^^. Btw, being curious about location and some private information is welcoming here as it is part of our norms, so no worries :))) Frank, Wow, so this one is the hybrid between the Sedum and Echeveria? Patrick, Ok, so it should be fine to leave them there a week before watering again. I also wonder whether gradual sunlight adjustment like I plan is ok or it is too long? P/s: about the ID yeah we should wait for more comments to confirm. These echies are sometimes too shy to reveal their true forms, or they just love to make us confused xD Thank you all for being very informative and enthusiastic in supporting me ^^

Are both the same? Or one or the other? Thank you and sorry for all the questions by the way
