Citrus, Japanese Hardy Orange, Bitter Orange 'Flying Dragon'

If this plant gets out of control it will be a nightmare for restoration workers: Here's an article explaining the problem:

In addition to commanding respect because of its spines, Poncirus "has become extremely invasive" under certain conditions, according to horticulturalist and noted azalea hybridist Bob Head of Seneca, South Carolina-based Head Selects and Head Ornamentals (a plant marketing and licensing company).

Having observed entire thickets of Poncirus in out-of-the-way places while hunting in locales throughout the South Carolina Piedmont, Head says, "One of the major concerns with Poncirus is that many river bottoms in national forests and other places where land would have been under cultivation at one time have been invaded by it."

I moved in to this house in 2008 and it contains a Japanese bitter orange tree on the side of the house. I never seen one before and didn...Read Moret know what it was until I did research on it. It is a very old tree. The people who owned the house came her in the late 30's so you can imagine how old it is. There are a lot of dead areas on it. It was not taken care of. So this year I trimmed it back a lot. It was very bushy. It hurt a lot to trim it even with gloves. But it looks a lot better and is still producing fruit. The birds like it a lot to keep away from my cats. I dont think it would be a good plant for small children to be around. It can put a eye out. One lady I talked to said if you fell into one you might not live through it. But overall I think it is a great converaional piece.

Darius left one here for me 4 years ago. It finally bloomed last month. I wonder if that means it will make fruit this year?

Yes, they are edible. We made kind of a lemonade out of them one year. It tasted kind of like lemon and kind of like grapefruit. The only problem is the peels are kind of gummy and make your knife and cutting board VERY difficult to clean. I love these trees, and get many compliments on them. The foliage is beautiful, and they look pretty amazing covered with oranges way up in Virginia!

So this is an orange fruit plant that has thorns....?

Several years ago I planted GRAPEFRUIT seeds and the resulting trees...Read More grew to be about 3 feet tall (they eventually died -- the pots were on my windowsill). The stems and leaves were greeen and glossy.

BOTH trees had LOOONG thorns -- I've been to Florida a number of times and have NEVER seen a grapefruit tree with thorns-- so, in my case, what happened with my grapefruit trees -- were they related to this thorny orange tree, or did they have recessive grapefruit genes???

I planted a hedge of the Hardy Orange about twenty years ago and for the first decade kept it sheared at about four feet high. My mistake...Read More was that I missed a couple shearings and it has become so intertwined it's nearly impossible to cut without getting stabbed in the process. This plant could truely stop a vehicle from penetrating a boundary line, if that was your intent. Incidentally, the fruit is great for holiday decorations and the mild citrus scent given off when brought in the home is real plus. Also, these fruit self seed very easily.

Although a slow grower for me, it is a really neat plant. Just be careful of those thorns!

The fruit appears to grow on branches which have no leaves or have lost their leaves. Branches with leaves have no fruit and have smaller thorns that the fruited branches. I cut one of the fruits and found lemon like pulp and seeds. The aroma made me want to eat it! It smelled very citrusy and sweet. It has a soft fuzz on the rind, somewhat like a peach. I have no idea where it came from, but I think there may have been one of these growing in the yard of a neighbor when I was in my early teens (more than 20 years ago!). I have done a web search and found several articles on this plant. Some say it is used in oriental medicine and others say it is poisonous.
