So I designed a self-watering planter for my hoya vines... This Kerri started as a cutting about a foot long in January of 2011, which I eventually stuffed into a small container made of two tiny plastic pots taped together and then put in a ceramic container that I made in Japan. The "Japanese" container doesn't have drainage holes, but as you can see the mineral deposits on it in the "before" pictures - it did let the water seep out. I was trying to make sure it pot-bound itself, because I'd read somewhere that it'll flower faster if pot-bound. Well, I didn't get a flower yet - and the plants wasn't as pot-bound as I was expecting it to be actually, but now I'm more entertained by the idea of training this plant to grow on the "trellis" I made for it than getting it to flower.
The new blue container is about 9 inches tall by itself, and the whole display is a little over 4 feet.
Thanks! If you like the pattern, you can shop online for it by Googling "Winton Graceful Vines", but don't use the quotation marks. The texture is from an impression mat used for decorating cakes with fondant. That particular one is especially nice, because it's a 20x20" square, so you can pattern a lot of slab all at once. I don't know if you can buy them in most stores, but there's loads of places on the internet selling them.
