Looking for trees that grow only 20 to 30 feet tall?
Question:tese trees will be grown close to a river
Answers:
First, it would be helpful to know which USDA hardiness zone that you're located in. You are likely to get answers that may or may not be hardy where you live. Take the list of answers to your local independent garden center, they will be able to help you select the trees that are hardy and available in your area.
I am in USDA hardiness zone 5, so the trees I'll list will survive in that zone.
Red bud (Cercis canadensis), Nannyberry viburnum (Viburnum lentago), Service berry (Amelanchier), Dogwood (Cornus florida, Cornus kousa, Cornus mas) and Spindle tree (Euonymus europaeus).
I hope that this helps
Good luck-

River birch, serviceberry, some alder
My favorite tree is the native Downy serviceberry, downy juneberry (Amelanchier arborea). This little tree is a cloud of white in spring with the first leaves showing as a pale copper. June is a crop of edible berries the birds will thank you for, then fall sees a pale gold show to end the year. The tree gets to 20', needs no pruning, no problems with seedlings.
Redbud (Cercis canadensis) likes average to moist soil just like the serviceberry. They would contrast well especially if you used 'Forest Pansy' a dark red leaved cultivar.
Redbud makes an effective companion for flowering dogwood (Cornus florida), as it blooms at the same time and enjoys the same growing conditions.
Pagoda dogwood 'Argentea', (Cornus alternifolia) is named for the horizontal layers the branches achieve. This is a standout specimen tree, good against a mixed wood backdrop. 'Argentea' is a smaller, shrubby plant (to 15' tall) with layered branches and leaves variegated with a white margin. Pagoda dogwood has fairly nice fall foliage in red to purple-red. Must have moist soil to be in sun. 15-20'
Rosebay, (Rhododendron maximum) a very showy native that blooms in large clusters of pink or lavender flowers. It does best in morning sun and afternoon shade. 6-15'

Combine these trees with Swamp azalea (Rhododendron viscosum) that has white flowers with a delightful, spicy fragrance. The flowers attract hummingbirds and grows to 5'-7'.
I would suggest members of the Sorbus genus (Rowan and Whitebeam), both small trees, very hardy, nice blossom and red berries. Good autumn colour too.
Mulberry is also a good choice, never exceeds 20ft even when mature. Long lived, very hardy and luscious fruits too.
Finally, Hawthorn is an old favourite. Agian is very hardy, nice spring blossom and autumn berries and never gets too tall.
There are many more to choose from but those are a few ideas.
Redbuds, Amur Maples, Japanese Tree Lilacs. Best bet though is to contact your local county extension office and see what they recommend. They will know what grows best in your area.
