The planters are just too adorable! The figures look like they are made out of concrete, however they are made of resin and each have a drainage hole at the bottom. The top of the head is where you would insert the plant. I love the way different succulents or house plants can change up the look of the figures.
Depending on the hairdo, one could mimic the look of an entire family for a good laugh.
Here is an image of the drainage hole on the bottom of the head. I would add a few pebbles at the base before adding soil and the plant. If you like to change things up frequently you could also just add the plant in it's original pot.
A short crop is fun too. I would think you probably would have to cut the plant into shape to retain this form.
All these pots are available from here
