Hyacinth holders are commonly referred to as VASES, which is a five-letter word. VASES are containers used for holding flowers, water, and other liquids. They are often made of glass, ceramic, or metal and come in a variety of shapes and sizes. Hyacinth holders are specifically designed to hold hyacinths, which are a type of bulbous flower. They are usually taller than regular VASES and have a wider opening at the top to accommodate the larger size of the flower.
