Sweet potato, eat every part of the plant!

Number three on my high calorie must grow foods is sweet potato. At 114 calories per cup of diced sweet potato it is a good source of carbs. However, sweet potato leaves are 65% carbs, 7% fat, and 28% protein. They are a great source of edible plant protein. Most people to not know that both the roots and leaves of the sweet potato are edible. This is why it is one of my top calorie plants. Because you and easily grow vines from cutting of existing vines. So you can create a large area of vines even if you do not get much in the way of tubers. I am always fighting to get the protein count up in the summer for my growing poultry. The vines pack a lot of protein when my birds are really needing protein to grow.

Recipes for Sweet Potato Leaves
Most people are unaware that sweet potato vines are highly edible. They also do not contain the high levels of oxalate that some greens can have. This can be a big issue if you get kidney stones due to high calcium water in your area. Sweet Potato vines are a great source of vegetable protein with a crude protein around 19.8%

Always purchase disease free where possible. You can grow one from the store but you do not know what you are truly getting!

Breeding sweet potatoes
Sweet potatoes are self incompatible with themselves, and breeders now interplant 15 -20 varieties and allow the bumblebees to cross pollinate the flowers. You may get one or two seeds per capsule pod. Most of the seeds will produce junk!
