You mean from the seed
? Yes, you could do that. Just take the seed
out and dry it.
However, depending on many things, you may not get similar fruit to the ones you purchased. If the parent plant
was hybridized, or the flower
cross-pollinated, they will most likely have different characteristics. MOST store-bought fruit and vegetables these days are hybrids and developed with storage and transport in mind.......not taste.
Why not just buy a packet of seed
and start some plants
that way? You can start the seed
in any size pot and just pot-it-up as it outgrows it. I think it's pretty late in the season down there to be starting plants
