these are 'rocket' planters by minali singh from qatar.
rocket is a reversible terracotta planter which can be utilized in two ways. smaller plants can be planted in the three small pots on one end of the pot. but the pot can be turned over to provide a larger pot space for bigger plants. the planter is made by attaching three small cones to a larger cone, thrown on a wheel.
at first i was drawn to the top image, with the three feet at the bottom as quite a nice detail, and thought that using them as small pots for herbs was a bit impractical. but then i thought about it, and it makes sense to me somehow. using the larger pot as a base or foot, the smaller pots are more stable than they would be as stand-alone pots, and just that bit higher up too.
