In my area of Hawaii, good sweet corn sells for $1.25 per ear. But it's dang difficult to grow!
A cantaloupe can
sell for $7 to $9 each.....again difficult to grow here.
A good pumpkin sells for anywhere from $4 to $10 each depending upon size. Finally! I can actually got them on my farm!
Tomatoes are $2.50 per pound....moderately difficult to grow good ones here.
Snow peas and snap peas can go for $7 a pound. Wow, I can grow them! But I don't ask that high a price because most of my customers are dirt poor.
Turmeric sells for $7 a pound, and I grow lots and lots of it.
New potatoes and new sweet potatoes can sell for up to $2 a pound, but I sell them at $1 a pound. Again my buyers are dirt poor. Plus I have to see them during the week around town, so I can't bring myself to gouge them.
