Produces masses of lovely white flowers in early to mid spring that are followed by bright orange citrus fruits which are very aromatic and give the tree an attractive interest. The fruits are bitter but can be used in making marmalade and the juice can be used like lemons. The fruits are also strongly medicinal. Very easy to grow from seed makes an attractive small tree, and takes well to being potted. It can also be grown as a protective hedge as nothing will get through the vicious thorns it produces. However wildlife love it. Pollinators and butterflies flock to the flowers the its a major host Giant Swallowtail butterfly caterpillars and birds love to build their nests in it as is provides so much protection from predators.

Description of Bitter orange or Flying Dragon (Poncirus trifoliata).
Small tree growing to less than 20 feet (6 m). It is hardy to zone 6 some say zone 5. It has been recorded surviving to -10 F (-23 C)! This was a rare one off occurance and should not be taken as 'normal'. It is the most hardy of the citrus trees and it sheds its leaves in winter unlike most other citrus. It is grown more for its interesting shape as the branches grow in twisted shapes that tangle together and are protected by long vicious thorns up to 2 inches (5 cm). The bark is noticeably striped making this interesting and attractive plant stand out even more. The thorns make it a very effective barrier for almost any animal or human.
The leaves are quite different from most citrus species being compound consisting of three lobes - hence its name trifoliate. Leaflets are mostly oval with wavy edges and from 1-2 inches (2.5-5 cm) long they are waxy, stiff and occur in far less numbers than most trees produce.
In early to mid spring the flowers appear in large numbers on old wood, making this an extremely attractive ornamental. Flowers are up to 2 inches (5 cm) in diameter which is larger than most citrus species but they are not as fragrant. Flowers are followed by globe shaped fruits orange from1.25 -2 inches (3-5 cm) in diameter. They begin green and turn bright orange and are very fragrant. These usually occur in larger numbers making the tree stand out and very attractive. The fruits are very tart and not edible raw unless the juice is extracted and diluted. Fruits also contain large numbers of seeds so preparation is required before eating. The plant is self fertile so only one is required to produce fruits.

Growing Bitter orange or Flying Dragon (Poncirus trifoliata) from Seed.
Seeds need a period of at least 30 cold before they will germinate. All our seeds are kept cold before they are shipped to you, we recommend placing seeds directly in the refrigerator on arrival until ready to plant. Sow seeds in individual pots in warm soils in late winter or early spring allow seedlings to grow and flourish repotting to larger pots for the first year of life, Plant out in spring of the second year after danger of frost has passed to give trees plenty of time to acclimatize to their new home.

Location and Care of Bitter orange or Flying Dragon (Poncirus trifoliata).
Full sun is recommended for colder zones but some partial shade and be offered in zones 7b and warmer. In cold zones (6a and higher) plant in a sheltered location or any discernable 'warmer spot' you have to ensure good growth. While plants will grow in more shaded locations they will not produce as many flowers or fruit.
Its not too picky about soil type or pH that is not really acidic. It will grow in almost any kind provided it does not stay water logged. Prefers light soils with some organic material for best growth, fruit and flowers However regular water is necessary if flowers and useable fruits are desired. A small amount of water twice a week maybe from a soaker hose around the base would be ideal during flower and fruiting season. This will ensure good growth of fruits grow well. If rainfall is sufficient then no water is required. Do not overwater or fruits may split. If fruit collection is not required then plants can be left alone they are fairly drought tolerant and would only require a little water in prolonged drought.
Trees are fairly slow growing so mulching around the base of the plants or use of a weed blanket may be desirable to help ensure that trees are not overrun before they become established, even then keeping are under the plants clear is desirable as weeding under these trees is difficult and unpleasant.

Pot plant.
Since its fairly slow growing Bitter Orange makes an excellent potted tree. It can be pruned to shape and makes looks very attractive when flower and fruiting. Ensure lower branches are removed to ensure easy of moving the pot. Keep slightly moist at all times as potted trees dry out much faster than those in the ground. If in cooler zones move pots to an unheated garage next to a window in the winter months. replace outside in early spring when temperatures have consistently risen to about 40 F (4.4 C)

Pruning of Bitter orange or Flying Dragon (Poncirus trifoliata).
Best carried out just after flowering, pick a cool day as you will need to wear thick gloves and coat to protect from the thorns. If planting as ornamentals to enjoy the fruits its best to keep an eye on them right from young and remove any cross branches and dense spots. A more open tree will look better give more airflow and produce more fruit that can easily be removed. If fruits collection is desired having a well pruned tree is essential otherwise you will need to wait until the fruits fall to the ground and pick them up. Ensure all lower branches are cut up the trunk so you can access the ground beneath the tree.
If growing and a protective hedge less pruning may be required. While good airflow is still recommended for healthy plants density may be more desirable. In this case leaving trees alone or just cutting into a shaped hedge may be the best option.
