One of the latest trends in horticulture are terrariums where you can create and assemble a miniature plant world to admire in your own home. A terrarium is a small glass case that allows you to grow plants with little effort or specialist skills. They act as a unique living space between indoors and outdoors. This is not a new concept as in 1800 Nathaniel Bagshaw Ward discovered he could grow a plant in a sealed glass bottle which would provide enough carbon dioxide and oxygen, plus moisture for it to survive. After this the Wardian case, a sealed portable mini greenhouse, was invented by Sir William Hooker. The Wardian case was used by many plant hunters to bring back live specimens of plants from far away places. They would arrive in perfect condition after being at sea for months. Terrariums act in the same way like mini greenhouses which can be decorated with coloured pebbles, moss, lichen and pine cones. When designing your terrarium select small plants and nestle them into a mix of soil and light grit for drainage. If the terrarium is sealed select plants which prefer high humidity such as orchids, ferns and venus fly traps and create a mini greenhouse. If the terrarium is not sealed you can select drier plant species such as cacti and succulents. Let your imagination run wild and create a miniature plant landscape for your home.
