Ichangquat tall tree growing near Paris
Someone else posted this in another forum and I wanted to share it here.
It's an Ichangquat (cross between Ichang papeda and kumquat) growing outside as a tall tree near Paris (France). That's pretty far north.
The tree is more than 7 meters high (23 feet), and I am told it was never protected but it is in a rather favorable position close to the Western wall of the house.
The fruit of this particular tree contains few seeds, about 1 seed per every 4 fruits (even though the normal Ichangquat variety is full of seeds). The pith is sweet, while the outer skin is more bitter.
Reportedly this tree has been in the ground since 2003 and has never yet been damaged by frost. Lowest temperature it has been outside was -16.5C (2.3F) but the spot where the tree was growing might have been a bit warmer.
Ichang papeda itself is very good at being able to survive absolute low temperatures, but isn't as good at going into dormancy and this can sometimes leave the plant vulnerable to cold. Kumquat is fairly cold hardy (the hardiest of the common citrus) but not nearly as hardy as Ichang papeda, but it is very good at going into dormancy, which helps it survive cold, and it is more vigorous growing. So it seems Ichangquat may have inherited desirable genes from both its parents that may help it better survive cold.

Comments (17)see link on general tree primer ... moving trees in dormancy.. or leafless is usually the best.. no loss of energy to try to hold the leaves on the tree ... and once leafless.. its done storing all the energy for next spring ... but.. where are you ... that might make a difference as to when to move it ... it will look brilliant.. smack dab in the middle of the lawn ... make sure there arent any utilities where he digs ... props to him for being willing to placate you ... yeah.. you should have started your own post .... with a searchable title ... but no need now ... ken check out TIMING >>> WATERING <<<< ETC ... https://sites.google.com/site/tnarboretum/Home/planting-a-tree-or-shrub...See Morecolumnar tree that will grow near black walnut?
Comments (0)Hello, I am looking for a narrow, tall evergreen tree. I am thinking about 10 ft wide (wider at top when full grown is okay) and about 25-40 ft tall at maturity. Unfortunately, the place I need to plant it is directly under the edge of the drip line of a black walnut. I have done quite a bit of online research, and I see some possiblities, but the walnut issue really throws me. I am using it for screening. The first 10 ft or so of the tree is the part I need to be most narrow, so some pruning would be doable. Wildlife tree would be nice, too. Not too slow growing either. Does such a tree exist?! Thank you for your wisdom!...See MorePlanting privacy screen near septic tank/leach field (tall fast shrub)
Comments (15)I don't see your zone, but I would use a mix of deciduous and evergreen shrubs, including some conifers. I would think that deciduous would be ok even where you want to hide the trailer, etc. since you probably don't hang out in the yard a lot in winter, though if you do all hollies there, repeat a group of hollies at least once somewhere else. Most shrubs grow at least as fast as the hollies you're presently interested in, though they'd be much wider, a plus as far as I'm concerned in that there would be less lawn to mow :). With a mix, you'd also get flowering and berries, and in some cases fall color. You might look at the huge range of Viburnums--V. sargentii 'Susquehanna' is about 15x15 and deciduous. V. pragense and V. rhytidophyllum (several cultivars available) are evergreen down to minus 10 at least. Groupings of V. dilatatum (many cultivars available) are also good. (To get good fruit set from the viburnums, you must plant at least two different cultivars of each species.) There are lots of others as well. Other shrubs include Magnolia stellata cultivars--very early, fragrant bloom and dense leaf cover-- and many gorgeous conifers with a range of colors from green to blue to yellow. Another tall, narrow conifer is Juniperus virginianus 'Taylor'--but it's hard to find and expensive. Since you have so much room, don't skimp on the width of this border. If you plant a narrow plant near a wide one, you can "thicken" the border in width smaller shrubs to face down the narrow one. If you spend the time to do this right, you'll have privacy, year round interest, low maintenance, and the value of your property would be increased. For conifers, the conifer forum suggest coniferkingdom.com or westernevergreen.com. Klehm's Song Sparrow Farm offers some each year too. One warning--don't make the border polka dot, though of course you can repeat certain shrubs. Hope this helps....See MoreAre these young native Persimmon growing near Oriental persimmon?
Comments (5)Once I started to really clear out around the main tree, I found a lot more suckers growing then I had previously realized. One, in particular, is growing about four feet from the main trunk and is about 2 inches in diameter and 15 feet tall which is as tall as the main tree (although not as well branched out). So, now that i see the number and size of some of the suckers, I am back to worrying if it is possible that removing them all at once might shock the main tree. Is the main tree benefiting from the energy derived from all the leaf growth on the suckers or is it strictly a one way street in which the suckers are simply sapping the energy away from the main tree?...See More

5 years agolast modified: 5 years agoHere's my precious seed that came from a hybrid between Ichang papeda x trifoliate. It's just beginning to germinate.
(It originated from the same person)Trifoliate and Ichang papeda are the two most cold-hardy citrus species, so this thing should easily be able to survive zone 7 when it becomes a bigger plant.
He tells me this hybrid barely has any of the characteristic bitterness of trifoliate, and the fruits are bigger and better quality than one might expect from such a hybrid.
Being a second generation seed, it's possible the genes got mixed around again, so this seed could possibly be a bit different from its parent.
(If there are desirable traits that have recessive genes, or undesirable traits with dominant genes, it's potentially possible for a self-cross from a hybrid to be an improvement)
The hybrid shows intermediate leaf characteristics between trifoliate and monofoliate, but mostly monofoliate.
