Allow ready-mix cement to cure 48 hours before walking on the cement terrace you have created. Now there are several options for usage. You can set stools or a bench there with potted plants strategically placed in the shade created by the patio furniture. Or you may decide you want plants on a baker's rack or other shelving that will create shade for the plants by the very nature of the shelving itself. You may also opt to place some potted plants there and move them back into the shade in the times when the region in which you live experiences a drought.
Roses do really well in large pots and flourish in full sun as long as they are watered regularly.
If you don't have money for patio furniture, barrels make cute seats or use large plastic cubes found in discount stores. Crating is a rustic look for tables. Potting takes on new interest when unusual items are transformed into homes for flowers, bushes, and even small trees. Old paint buckets offer excellent possibilities, once they are thoroughly washed and aired. They are fun to spray paint to match your patio furniture or even in colors that match your flowers in bloom.
