I’ve planted 3 decorative trees since purchasing my home in 2016
A Stellar pink dogwood that my wife wanted. we have had a load of issues with it, and still no flowers, but the fall foliage is very pretty
An October glory red maple that my wife wanted. still small, but the fall foliage is pretty.
A Prairifire Crabapple that I wanted for the pretty pink spring blooms and decorative fruit in the fall. maybe one day I might try and graft some no-or-low-spray apples to it.
I plan to have a few other decorative trees planted in the future, like a virginia magnolia, and a pink pom poms redbud.
nothing wrong with growing trees that don’t produce fruit or nuts.
Of all the trees I grow, the Asian persimmons, specifically those with good red fall foliage, make the most sense as a landscape tree.
Cornus mas are nice for their very early spring blooms, although not as showy as forsythia
