I'm really new to house plants, and I never really paid much attention to these while they were at my grandparents' and later my parents' home. I did notice that the "soil" is really spongy and light, not very similar to outside garden soil. I'll have to ask my mom what she's planted them in. I was just very surprised to see these cute little mushrooms appear! And I am very interested in watching them grow, so maybe I'll wait awhile to change out the mix in the pot.

Sounds like The Flower Pot Parasol, or "Spirit Cap" (latin name: Lecocoprinus Birnbaumii). Those yellow mushrooms are beautiful and harmless to the composting process, or your flowerpots, should you ever catch them growing there...as that's the most common place to appear. While the reports on it's actual toxicity are still out, they should be considered inedible because a small percentage of people have reported severe gastrointestinal upset from consuming them. But no, they won't harm your composting and in fact, they're helping speed it along by breaking down complex carbohydrates and cellulose into simpler sugars which will be further consumed when they, themselves begin to rot. Here is a link that might be useful: The Wikipedia link on Leucocoprinus Birnbaumii

Barbara, I think the 'Lemon Spire' is just a renaming for what is in reality 'Suecica Aurea'. This could be for it's Latin name which doesn't say nothing for a lot of people. The #2 isn't a Juniperus communis, it's a Juniperus chinensis and it's cultivar name is 'Aurea'...

Danielle...it would be best if you don't post same question in different posts - it gets confusing. Starting thread as you did this one is the way to go. I actually answered on other thread you asked this same q, so here is the copy - keep just one thread on specific subject going, you'll get better response: copy from another thread: First of all, there is probably still some time before they should go indoors. If temps drop to about 50*F for just a short time (hours or two) overnight, it's still not too cold.It also depends on what plants you have, but many succulents can stay outdoors until temps are consistently staying just below 50*F. Could you post names of your plant if you have them or at least photo of them? The hutch idea is not so good if you are thinking to close the door. DON'T, succulents need air circulation, you'll suffocate them if you do. If you use it as a shelving-storage and keep door open, it could work. BUT, it will be very dark in there - maybe you can put some lights in there? Take photo and post, there are some other things you could possibly do with it but need to see it. And how much "damage" could that hutch take - you need to think about possible water spills and so on. They really don't have to be super warm during winter and especially if they are in relative dark location. It is always big concern for all of us in colder climate when weather cools off...we all have to be creative! Rina
