The next day the area may have a inch of water left and by the third day after the rain the standing water is gone.
The soil is clay here.
I'm in central Indiana and we get heavy rains in early spring, then again around July. In August the area is pretty dry and I have to water August and September.
I've read that they want a moist soil and some places say moist well drained. I have a flowering dogwood in a higher, dryer area and it has always struggled.
How often does this happen? Once a month for 6 months in the growing season?
Once in mid summer? every week? Only in spring.
I have some Cornelian Cherry. This is their 11 month with me. They are already flowering. The site is super shaded but well drained.
The dogwood I have now that struggles is planted close to the house and does not get standing water.
In about 2 minutes I found 3 species of dogwood that loves water. So I think that cornus mas will be ok with a little standing water.
I just found a link and it seems that although cornus mas prefers well-drain soil, it is very tolerant of wet soils at least according to this nursery
Edit::: Sometimes I feel that if someone were selling pet humans they'd come with instructions reading, "keep in approx. 70 degree F. temperatures (20 degrees C.) in well ventilated areas. Space approx 6 ft.from other humans. Provide nutrients daily and fertilize with anabolic steroids monthly for best results."
But some will tolerate shade and wet feet.
