One way to decorate your patio is with live plants.
Plants can create a sense of enclosure and privacy.
Vines are very good for small spaces.
Garden structures such as trellises can help them to grow upward without taking up too much of your valuable patio space.
Evergreen shrubs such as boxwood provide structure and greenery all year round and can be clipped to maintain just the right size to fit your space.
Local nurseries can recommend exactly what types and species of plants will do well in the climate zone where your patio is located.
As far as furniture, consider the size of the space you need to furnish.
For example, a 48 inch round table with four chairs will need 10 feet by 10 feet of space for comfortable use.
If you need to store your patio furnishings during the off-season, consider folding chairs and tables or use covers to maintain your furniture during the off-season.
The choices for the material of patio furniture range from wrought iron to all-weather wicker to recycled plastic.
Most of them are maintenance-free and metal such as aluminum will be rustproof.
Teak is considered the best wood for outdoor tables and chairs because of its ability to withstand the elements and age gracefully.
Other accessories for your patio might include a fire pit for a family barbeque.
Lighting options such as string lights and tiki torches improve visibility and safety.
Small gas heaters will allow you to use your patio year round.
Umbrellas and awnings will provide an oasis of shade on hot and sunny days.
