Each of these art-glass watering bulbs is individually hand blown in Europe. Not only are they beautiful to look at, but they will also water your potted plant for up to a week. Water the plant normally and then fill the watering bulb with water, poke a hole in the soil with a pencil, and insert the stem into the hole. As the soil dries it will draw the water from the bulb for up to 7 days, depending on the plant.
