Malabar spinach, Ceylon spinach, or Indian spinach, Basella alba and/or B. rubra
Malabar spinach grows well in hot climates. Plant seeds when weather warms up, or it will reseed itself and sprouts emerge when temps warm; mine started sprouting in June from self-sown seeds.
You will probably want to trellis your plants because they are a vine. There are two varieties, Basella alba
which has green stems and white flowers that turn to deep purple fruits & Basella rubra
has deep magenta stems and pink flowers, turning to dark magenta fruits.

The leaves and flowers are edible. The texture is more meaty than spinach but the flavor is similar.
