I have a kousa dogwood that has been blooming beautifully for 12 or 13 years now. My wife and I love it. Recently we noticed what we assumed are seeds underneath the tree (and seedlings growing up underneath it) but we're not sure whether the seedlings are from the kousa dogwood or they just blew in from somewhere else. The seeds that dropped look like blackberries (about the same size -- round with a lot of little globular things that make up the "berry" or seed. How can I plant them to create more trees -- or is nature doing it for me under the tree already? If I wanted to plant some in some potting soil would I do it now, or wait til it turns cold? Would I keep the pots inside or outside, and how deep in the pots would I plant them? Thanks everyone. By the way, I live in zone 7.

I have a Cornus kousa, var. angustata that blooms in June and is reliably evergreen in SC. It is planted under mature hardwoods and its lime green leaves are a striking contrast to the dark hardwoods forest in winter. The tree is probably 15-18' and produces edible fruit and lots of seed. I planted some last fall that are from 6 - 12" now. I'm harvesting seed now to plant in pots in the yard this fall.

I raised my Kousa dogwood from a 15-inch baby to its present 12-15 feet. It has flowered for two years, and the bracts last and last. However, this year it did not flower. I'm at a loss and would appreciate some feedback. On the whole I gave it a positive rating because those two years were worth all the trouble--but I want MORE!
Help is what I'm actually looking for. I bought my cornus kousa this past Oct./Nov.(02189-zone 6) and put in ground within a week or two because of much rain at the time. Bought in I think in 3-4 gal. container. A small speciment but it was the tree that I wanted so bad, having seen them in wonderful park designs; and the tree was in very good condition. I Know that we had a relatively late frost and I watered,fertilized, & applied bonemeal. All aseemed well and tree looks healthy, but I'm astill waiting for the buds 'n leaves. What am I doing wrong or not doing? Am I overwatering maybe (once a day)?HELP!!??!! Can anyone help me or is my cornus kousa a goner?

In Petersburg, Southern Virginia, Zone 7A, we planted a Kousa Dogwood twelve years ago. My husband has expressed disappointment that it does not have the more graceful and fanciful shape of the native dogwoods. Unfortunately, the Cornus florida have been afflicted by anthracnose, and most seem to succumb upon reaching maturity. I pruned our dogwood by limbing it up and that did reduce the stockiness of its appearance. It is very pretty and healthy. I'm hoping it will crossbreed with the native dogwoods in the neighborhood, as the hybrids are supposed to be able to resist the anthracnose.
My daughter bought me this plant 5 years ago and we planted it in the front of my house. I love the flowers on this plant but I also had some trouble last year. I thought it was dying because it only had 2 flowers on it and hasn't really grown very much in the last 5 years. However this year it looks great and full of flowers, beautiful!!! It still has a long way to grow but I am glad it is doing better this year. I first saw 2 of these trees in Princeton, NJ, on 206 near a strip mall. That's when I fell in love.....They are both tall and have big beautiful blooms each year. If you're in the neighborhood, check them out....

I can't find enough praise for this plant, even if it is an exotic here. I have two plants that are nearly 25 years old. One was trained into a single stem tree and the other was allowed to become a five-trunk shrub. Both plants are now old enough to begin to show their natural bark exfoliation that results in a very pleasant patchwork of putty and green earth tones. Their foliage, flowers bracts, and fruit often show simultaneously (see my image) and give a pleasant 'crazy quilt' appearance. In the fall its foliage will assume a bronze color before it drops. Quite a color spectacle for one plant! Usually our squirrels harvest the ripe fruit before we get a chance. During this year's drought the trees that were deep watered showed less stress than those that received less supplemental water. Also good to remember is that this plant is an understory tree and prefers mostly shade. But if you plant it under another larger tree the larger tree will tend to hog the moisture in the soil. In that situation some additional irrigation may be needed. Other than that it's a carefree tree with a long life expectancy.

I have had 3 of these trees since 2001 and when they bloom they are lovely and long lasting with the flower starting out green, brightening to a creamy white and then fading to pink. However, flowering seems finicky and I have not figured out why it does/does not bloom.

I planted two of these trees in my yard early this spring. They are in an area with light shade part of the day, and I was careful to plant them with good soil, etc. But only one is showing signs of life! One has beautiful baby leaves budding all over. The other has crispy brown stubs that look like they started to come out, then died when they saw daylight.
I am not sure if the sad one is totally dead, or if I just need to be patient another month. I'll upload some pics to illustrate.

Good small tree for flowers, fruit and winter interest. The bark on mature specimens is beautiful and adds much interest to the winter landscape. The flowers bloom later when many people are outdoors to enjoy the display.
I have a Kousa that was planted for me four years ago. Last year it was covered with blooms; however this year, there is not a single bloom on it...has anyone else had such an experience? So far I love the tree, but am perplexed by the sudden lack of blooms!

I prefer the Kousa to my native Cornus Florida. The flowers are longer lasting and appear after the spring rush. Mine are sensitive to drought but well worth the watering here in S.Ontario. Easily obtained here.

The true flowers of this species are small; the bracts surrounding the flowers remain for many weeks, gradually changing color from white to pink. Highly garden-worthy replacement for those unable to grow Cornus florida. Many cultivars available; new ones are introduced every year.
THE TREE--A smallish tree, growing best in part sun. Most of the variety I have seen are no more thant 15 - 20 feet in height. However, I have seen a large old specimen in Pennsylvania that was probably 40 or 50 feet tall. Unlike the Cornus Florida, its flowers come out after the tree has begun to leaf out.
DISEASE RESISTANCE--Apparently resistant to the anthracnose that has begun to devastate the Cornus Florida. The Cornus Kousa is a wonderful tree to replace the Cornus Florida. One might plant one very nearby a diseased Cornus Florida and then remove the latter when it dwindles to the point of becoming an eyesore.
FRUIT--The fruit is of the size and color of a red raspberry, and is in color in August and September in the Washington, DC, area. I have a seedling about 15 feet tall. The fruit on mine is largely seedless. It is sweet, pleasant, and has a flavor and texture similar to that of a pear. I have noticed no reaction when I have tasted it. I have yet to cook it up. I expect that it would make a flavorful sauce or a delicate jam. Because of its delicate flavor, I would make either a freezer jam or cook it with pectin.
