Goji plants, also known as the wolfberry, produce berries that have been described as tasting like a cross between the cranberry and cherry. We find that to be far more appealing than ground cherries which were (accurately) described as a cross between a tomato and pineapple. Goji plants grow up to 13' tall and 4' across, but can have their size managed through pruning. They also can be potted which controls spreading.
Goji fruit is expensive! In doing a little digging, I've seen prices of dehydrated goji berries between $18/lb online to $22/lb at the local MOM's today.
Growing goji
As I mentioned before, goji can get rather large, but can be potted. If one wants to grow them in a pot, they should have pots no smaller than 5 gallons since the taproot extends up to 8" below the soil. Water well in the first year and they can be reasonably drought tolerant later. It likes a pH 6.8 to 8.2 with low levels of nitrogen. They should be given something to climb on such as a trellis. After the first year, be sure to trim their branches below 16" from the ground as they grow taller to decrease chances of fungus growth. To encourage more growth, prune in the spring. Few berries will be produced in the first year; yields increase in subsequent seasons. It's recommended to use bird netting to deter non-human snacking.They can be grown in a wide variety of climatic zones from 3 to 10. Preferring full sun, they can handle temperatures as low as -5 F.
Although there are no recommended companion plants, it's recommended to keep them away from potatoes and tomatoes to prevent the spread of blight diseases.
Ripe berries will be a deep red with a shiny skin. They should readily fall off in your hand when you try to pick them. Be careful when harvesting as they will crush easily.
Nutrition Information
Although there are many sources claiming nutritional benefits of goji consumption, finding reputable sources of information has found to be a challenge. While I hate quoting wikipedia, it's the best I've found.In 100 grams of goji berries, 8-10% RDA of calcium, 24% potassium, 100% iron, 18% of both iron and zinc, 91% selenium, 100% vitamin B2, and a significant amount (percentages vary from 32% to 163%) of Vitamin C. There are also a number of amino acids, poly and monosaccharides.
