Looking for the prefect plant for this container..please help !

If it doesnt have holes, you might want plants that don´t need much watering. I love cacti and succulents and you could mix coarse sand with a bit of common soil, get three very small and different cacti and plant them there. I cover the soil sometimes with quartz or other coloured pebbles. That helps mantain humidity without having to actually water it much.

That is a really cool little container!! I have different containers that have no holes in them for drainage too, so here's a couple things that I do. I plant whatever into a smaller plastic pot, and then insert the plant into the container. After I water it, I dump out the excess water so it's not standing in it. Another thing I do in other pots, is to put some gravel in the bottom, and put plants in that do suck up water more than others (like the impatiens.) If it's going outside the sun and wind will dry it out quick so you don't have to worry about soggy roots. I have a head container from back in the 50's, there are no drainage holes, and since I keep it inside all of the time, I have mother-in-law tongue in it so I don't have to water it but a pinch every once in a while. Hard to tell what size your pot is, but I'd probably put in something in it that is shorter growing and keep it pinched back so it'd look like hair lol.

I'm thinking something low, mossy and trailing will enhance the shape of that pot. Or maybe something that speaks to the origin of the pot. Where does it come from? What does it represent? Also, if you're just sitting another pot inside of it, maybe you could camouflage it with some moss or other material to give the illusion that you've planted directly in the pot. If drainage is an issue you might want to try putting some stones in the bottom of the planter. xoxo Cyne
