If you are looking for a way to grow citrus in small spaces or colder climates, finding a Flying Dragon citrus tree is often the first step. This unique variety, officially known as Poncirus trifoliata ‘Flying Dragon,’ is prized by gardeners for its extreme dwarfing capabilities and its hardiness. Whether you want a potted lemon tree for your patio or a cold-tolerant rootstock for your orchard, understanding where to look and what to identify is essential.
What Makes Flying Dragon Citrus Unique?
Flying Dragon is not your typical citrus tree. It is a cultivar of the trifoliate orange, characterized by its distinctively twisted, contorted branches and curved thorns. While the fruit itself is very sour and seedy, the tree is most famous for its role as a rootstock.
When a standard citrus variety, like a Navel orange or a Meyer lemon, is grafted onto Flying Dragon rootstock, the resulting tree remains naturally small. This makes it the gold standard for high-quality dwarf citrus trees that can thrive in containers or small backyard gardens.
Key Characteristics of Flying Dragon
- Extreme Dwarfing: Trees grafted on this rootstock typically reach only 5 to 7 feet in height.
- Cold Hardiness: It is one of the most cold-tolerant citrus relatives, often surviving temperatures well below freezing.
- Visual Appeal: The zig-zagging branches provide a striking architectural look, especially in winter when the leaves have fallen.
- Precocious Fruiting: Trees on this rootstock often begin producing fruit at a younger age than those on standard roots.
How to Locate Flying Dragon Citrus for Sale
Finding this specific variety can sometimes be a challenge because it is a specialty item. Most big-box garden centers carry general citrus, but they may not specify the rootstock used. To find a true Flying Dragon, you usually need to look toward specialized sources.
Search Specialized Online Nurseries
Online nurseries that focus on edible landscapes or rare fruits are your best bet. Many of these businesses ship nationwide, though they may have restrictions based on agricultural citrus zones (such as Florida, California, and Texas). Look for sellers that specifically list ‘Flying Dragon’ in the product description or as the grafted rootstock option.
Visit Local Citrus Specialists
If you live in a citrus-growing region, seek out local nurseries that propagate their own trees. These experts are more likely to use diverse rootstocks to suit local soil conditions. You can ask them directly if they have any trees grafted onto Flying Dragon or if they sell the rootstock liners for you to graft yourself.
Check Rare Plant Exchanges
Gardeners who specialize in rare fruit often trade seeds or cuttings. While growing from seed will give you the Flying Dragon tree itself, remember that if you want edible lemons or oranges, you will eventually need to graft a scion onto that seedling.
What to Look for When Buying
When you find a source, it is important to verify the quality of the plant before purchasing. Because Flying Dragon is a slow grower, these trees may appear smaller than other varieties of the same age. This is normal and expected.
Inspect the Graft Union
If you are buying a grafted tree, look at the base of the trunk. You should see a slight bump or scar where the fruit variety meets the rootstock. Ensure this area is healed well and shows no signs of oozing or peeling bark.
Check for Vitality
Even though the branches are naturally contorted, the leaves should be a healthy green. Avoid plants with yellowing leaves or signs of pests like scale or aphids. The roots should feel firm and not be circling tightly within the pot.
Planting and Caring for Your New Tree
Once you have secured your Flying Dragon citrus, proper care will ensure it remains healthy and productive for years. These trees are relatively low-maintenance but do have specific preferences.
Choosing the Right Location
Flying Dragon prefers full sun, which means at least six to eight hours of direct sunlight daily. If you are planting in the ground, ensure the soil drains well. If you are using a container, choose a high-quality potting mix designed for citrus or succulents to prevent root rot.
Watering and Fertilization
Citrus trees like consistent moisture but do not want to sit in water. Water deeply when the top inch of soil feels dry. Use a balanced citrus fertilizer during the growing season (usually spring through fall) to provide the micronutrients like iron and magnesium that these trees crave.
Common Questions About Flying Dragon Citrus
Many new growers wonder if they can eat the fruit from a Flying Dragon tree. While the fruit is technically edible, it is very bitter and contains many seeds. Most people use the fruit only for its juice in marmalades or as a garnish, rather than eating it fresh.
