Almost certainly those are seed grown trees, and assuming that is in fact the case, you may be waiting a few more years. Seed grown trees have to mature for a number of years (only they know how many) before they will flower. A grafted tree, takes a branch of another tree that becomes attached to the rootstock (another probable seed grown tree). This grafted portion "knows" that it is already some years old genetically, and therefore will begin flowering earlier.

You likely seed grown tree will flower, but nobody can say how long that will be. BTW, flower buds are set in late summer the year before flowering, so you can examine your tree in the fall and determine if it will likely flower the following spring. The flower buds look kinda like an teardrop shaped onion in shape.You can find pictures on the net.

Arktrees

Arktrees' response is right on the money. In addition to a long wait for any bloom, you also have no way of knowing anything about the ultimate size, flower quality, etc., etc. of a seed grown tree as opposed to a named cultivar. This is an excellent example of how those "bargains" at the big box stores often aren't.

It'll be worth the wait. In addition your tree is working on producing a strong root-system these first five years of its life. And as the others are saying, seed-grown is different from a grafted tree.

Grafted-trees already have mature wood that has flowered so they will flower at an earlier age.

Be patient; you'll be happy with it.

I was using Miracle Gro Bloom Booster last year and was advised to discontinue that as it does nothing for this tree but encourage new leaf growth and no bracts. Did I get a defective tree?

==>> brilliant advice ...

flowers are an expression of the sexual maturity of the tree ...

it will become mature.. when it will .. there is nothing you can do .. to speed it up ...

transplanting it.. may or may not have slowed it down ...

all you can do is wait ... IMHO

Fluffy, how is the fall color on your cornus kousa? Pretty good I bet.

Also, your tree has some advantages over the grafted ones. Yours has no graft line resistance to nutrient movement that causes the rootstock to sucker. Yours also is not a clone prone to the exact same dieseases as every other clone sold.

Hi, everyone!! In response to Toronado3800, yes in the Fall, the leaves are red and robust; so pretty to look at and admire, so there's that:) There are no suckers at the root which is nice---there are many on my 2 Cleveland Pear trees. Hoping that patience is all it takes; it's a fine tree in and of itself; just looking forward to flowers and berries:)
