The fruits can be green and cylindrical in shape, up to 100mm long and only about 20-30mm in diameter. They have a thin skin that ranges in colour from green, yellow, red, purple to even a black. The inner cells are cylindrical balls filled with lime juice.
Citrus rootstock used to dwarf the variety grafted onto it. It is a mutated Trifoliatia species which has hooked thorns and much slower growing. Due to the difficulty and slowness in growing Flying Dragon, Citrus varieties grafted onto this variety are usually more expensive. It imparts the same characteristics to the scion, including cold hardiness, tolerance to root fungi and nematodes. The bitter fruits can be used in marmalades and marinades.
