Hey Xuan, You have some nice specimens there. =] #1 Unknown (probably Echeveria of some sort) #2 Echeveria Pulvinata - Plush Plant (maybe not exact match) #3 Aeonium Haworthii variegata #1 and #2 can enjoy part sun and some shade; Sunlight will keep the reddish tint. Indoors they will lose that reddish tint and will revert to a more green form which is up to your preference. #3 is good in a shaded spot or in a bright location in the home. Let the soil dry between waterings; don't keep too moist. I hope some of this helped. This info is based on my own research and experience so if anyone else has any additions or corrections, please post! =] -Joe

Did you mention where you live? (Good idea is to put general location and/or growing zone next to your name...) Yes, Sempervivums could be grown indoors but usually they don't look their best. I am not sure if they are better off with having to spend winter outside (some plants have to have x number of cold days to grow well); unless you get them really good light during winter they usually look quite sad. During summer it may not make that much difference. But amount of light is always less indoors than outdoors. But if you don't have access to garden or deck-balcony, you have to just do it indoors. Many ppl have to, living in apartments without balcony or any other outdoor space. All of the succulents need lots of light otherwise they stretch as I already mentioned about Painted lady. I use lots of supplemental lighting in winter, and probably will improve even more next winter. here is same Echeveria purpusorum, still indoors (March) and blooming, under lights: Adding more perlite definitely helps.

I can't tell what type of Tillandisa it is (they all look the same to me :P ) but you could try posting in the Bromeliad forum. As Tillandsias are bromeliads and I believe it is the use gonzer who seems to be the over all Tillandsia expert. He can probably provide you with an ID. For mine, I usually soak them in my fishtank (or in a bowl of water) for 20-60 minutes about every 2-3 weeks depending on the time of year and the weather. Mine have survived a whole month without water (don't recommend doing that) but have quickly rotted when left outside in a week of rain. Thus, as with any plant, it's better to keep them on the drier side if youre worried about over watering them. Be sure to thoroughly shake them off once removing them from the water as to reduce the risk of rot. I usually leave mine to dry upside down or at an angle to make sure all acess water is removed. Make sure they get a lots of air circulation while drying off and also where they are going to be positioned. I also find its better to water them early in the day so they get a chance to dry off before night.

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 ^^
