When looking for finishing touches for a room or an office a large plant with plenty of height can add a distinctive look that softens an area and adds something tangible for people to appreciate. Tall plants sit nicely in a corner or even next to items of furniture where they do not impact on floor space too much.
When you buy large plants they are normally supplied in 10-14 inch pots which can then be placed in larger planters or decorative containers to fit in with the style and decor of a room or office. You must however remember to add a drip tray to allow for drainage, though you must be able to get to the drip tray easily to allow for maintenance and removal of excess water. To cover the gap between the nursery pot and the planter you can use foam or moss or something akin to those.
