The native Dogwood (Cornus florida) lives as an understory tree, growing between the lower shrubs and the upper tree canopy...
...growing slowly in these open, but shady areas.
It grows 15' - 30' in height, is short-trunked, dividing low, with slender spreading branches forming a flat-topped crown.
In SW Michigan, the Flowering Dogwood reaches its northern limit in our Grand River Valley. Found in Oak and Beech-Maple forests.
These spectacular white blossoms you are viewing are not blossoms!
Botanical truth: these are four, white notched bracts that resemble petals.
That cherry-colored notch on each bract used to be a bud scale; a protective winter covering for the future flower.
These showy white bracts, conspicuous from a distance, attract insects for pollination.
The true flowers are in the center. Greenish-yellow and tube-shaped before opening.
About 20 - 24 per cluster.
Try to recall your Biology or Botany classes. These are bisexual flowers -
having both male and female sex organs; also called a perfect flower.
Dogwood leaves are arranged opposite, as opposed to alternate. Their petioles (leaf stems) are short and grooved.
Leaves are clustered at the ends of slender twigs:
Within the leaves, find the nicely curved, parallel veins.
Look at all the parts bursting forth from one terminal bud!
How to age a tree twig? In this next photo:
- Start from where the twig divides into two
- Count each half-inch segment: 4 segments = 4 years growth
- Newly emerging pair of leaves = 5th year, for that twig's age

I purchased this for a Dendrology class in 1967. A Dogwood leaf
is still pressed on page 237. It's 45 years old!
This piece was detailed and infused with Botanical terms. I believe the most miraculous thing about these intricacies of God's nature, is that it all works!

Lovely photos. I live in SE Michigan, Ortonville to be exact. I am a native plant lover too.
ReplyDeleteMary: Thanks for responding. Please visit WWFN often as the seasons progress in our magnificent Michigan. I'll try to present a unique perspective on the native plants we both love.
ReplyDeleteI always admire these at this time of year on blogs - the dark pink ones are my favourites....though they may be a more cultivated one rather than one from the wild.
ReplyDeleteGorgeous photos throughout your entire blog. I enjoy reading and learning about the plants and trees you see where you live and travel.
ReplyDeleteI also see that you've also lived in Arizona before and that your camera has captured its beauty.
What a lovely find your blog is. I will be back to explore often. Thank you for visiting my blog too and for your nice comments.
The dogwood in our yard was so beautiful this spring. I clipped off a short branch and brought it in for my mom to see. She cant get out much so I bring it in to her. Wheather its the real thing or that I take a picture of it and show it to her on my camera.
ReplyDeleteAnn Marie:
ReplyDeleteYou have always been so kind to your Mom. Give Clara a hug from Rich. Please read some of these posts to her. She will like it when I mention Aaron and Sarah... and of course Mary.
Thanks for following.
