What is "tulipiere"

A tulipiere or tulip-holder is an ornate vessel in which to grow tulips, and is usually made of hand-crafted pottery, classically delftware. They are typically constructed to accommodate one single bulb per spout with a larger common water reservoir base. They were not designed as vases for a cut bloom, as is sometimes supposed, though they could also be used for this. The boughpot and flower brick were types of vase for this.
