I transplanted a few succulents into glass jars earlier this week to add some greenery to a new side table in our living room. My mom scored all three plants for just $4 (the horticulture department at her local community college was selling that semester's work) and I found these glass jars at the Dollar Store for $2 each.
I lined the bottoms of my jars with a layer of stones about an inch thick (for drainage), then added my dirt and my plants. You can buy cactus or succulent potting soil (I just used what they came with) at any gardening or home improvement store, which is more sand-like than regular potting soil and drains really well. The most important thing to remember with succulents is not to overwater them. I've read that misting them with a water bottle once a week works well, but I'll let you know how it works for me.
Here they are in our living room, with a better view of the new side table (now we just need to find the perfect area rug). Who knows if this is where they'll stay, but I love having more plants in the room!
