Firecracker' Goji Berry' Plants - Lycium barbarum 'Firecracker', cultivar can flower during the very first year of planting, but the purple star-shaped flowers or fruit set should be removed when they develop, so that the full force of production energy will go into increasing the size of the bush, and not early berry production, since the nutrient draining process of juvenile flowers causes the developing plant growth to become static.
A real danger lies in maintaining the vigorous vitality of the Goji plant. In the instance of a Goji berry bush flowering at too early of an age, there will not be stem and branch longation size, and that ultimately results in a reduction of future berry yields. The mature clusters of 'Firecracker' Goji berries develop an explosive red coloring on the skin, and the fruits are easily dislodged from the stems by gently rolling the Goji berries with a finger into the palm of the hand.
Firecracker Goji Berry is self-fertile and will produce fruit with only one planted. Yields do increase with an increase in pollination, which can be accomplished by planting in pairs.
