Nothing says tropical more than tropical plants. The most well known tropical plant is in fact the Arecaceae, more commonly known as the palm tree. There are in fact many thousands of different varieties, such as the well recognised coconut palm or date palm. However for indoors you may wish to consider much smaller varieties - of which there are also many. In fact there are a number that do not grow beyond five feet, ideal for indoor use.
In addition, rich brown leathers are very commonplace, as are other animal designed fabrics. Leopard spotted fabric can often look cheap and tacky, however, when combined with a tropical feel it eases in very nicely and actually looks much more refined . The same is true for zebra stripes and the like. You still need to be careful not to use too much of it, but small areas such as on cushions or floor rugs is ideal.
Plants come in all shades of green, and you will find that using contrasting shades will help you room look elegant and modern. In order to make the perfect green coloured bedroom, you will need the majority of the room to be a light, pale green. You will, however, need to have a few items of dark green in the room, such as a number of plants or dark green highlights on the patterns of the wall and duvet cover sets. Complete the green theme with dark brown or grey furniture and you will have the modern décor of class nature.
