Goumi berries are a rich source of vitamins C, A and E, lycopene and flavinoids, and it is considered to be a medicinal plant in China where it is used to boost immunity and lower cholesterol. The medium-sized shrub grows about 6 tall and has attractive silver-green foliage. Goumi plants are nitrogen-fixers. They take nitrogen out of the air and improve the fertility in the soil surrounding the plants. Fragrant flowers appear in spring followed in mid-summer by sweet, juicy scarlet-red fruits that have the flavor of tart cherries. Sweet Scarlet has proven to be self-fertile so you only need one plant to bear fruit. It starts fruiting the second year after planting and yields about 10 pounds of fruit.
