Here's my CatBus* plant pot sharing space on my window sill with a sunflower gogo crazy bone **. The planter originally came with potting mix and seeds but I couldn't bring that into the country. After a bit of trial and error I finally found the perfect plant to grow in him.
*Bought in Mitaka, Tokyo from the Studio Ghibli Museum gift shop. **Freebie from the Toy Fair last month.
