Malus ‘Tschonoskii’
If you are not familiar with the Tschonoskii Flowering Crab tree by now, you should definitely put it on your list of trees to check out. This tree has some fine attributes that make it stand out, and should certainly be special enough to get on your street tree list. The relatively consistent red fall color is especially striking, and it is the only crab I can think of with such a brilliant fall color. The tree also has very upright growth, important for a street tree, and somewhat unusual for a flowering crab. With ascending limbs, the mature shape appears to maintain a relatively narrow form into maturity. Branch attachment appears good on a strong central leader. Because of its ultimate height, Tschonoskii does not appear to be a tree that is proper to grow directly under power lines, but offset to either side should work.
Emerging leaves are frosty white surrounding fat light pink flower buds opening to white petals; not spectacular, but nice up close. Disease resistance is said to be good, but I have seen a little scab in the nursery. The more open and airy the site, the better.
I have been told that the fruit can be a bit of a nuisance. The crab apples are larger than a marble, but in a wide enough planting bed, the other qualities should make up for it. For some reason, most of the street tree applications I have seen have been fruitless. Others have reported the same. I am always looking for more narrow upright growing trees and this is another one to remember.
As always, let me know your experiences with Tschonoskii Flowering Crab.

Wondering how Tschonoskii Flowering Crab performs as a landscape or street tree?
Here are some common questions people ask about this tree:
Tschonoskii Flowering Crab typically reaches 30–40 feet tall with a 10–15 foot spread, forming a narrow, upright tree that works well where vertical presence is desired without taking up much lateral space.
Its upright growth habit and vibrant fall foliage make it stand out. Leaves emerge with a pale cast and turn rich shades of orange, purple, and red in autumn, while flowers are subtle white blooms from light pink buds.
Yes — the columnar form makes it ideal for urban corridors, boulevards, or narrow spaces where vertical impact is desired.
Absolutely — the fall foliage is the highlight, with bright warm tones that draw attention. Flowers are modest, and fruit is minimal, so it’s prized mainly for structure and color.
Plant in full sun with well-drained soil. Proper early care and spacing help maintain the upright form, and good airflow around the canopy supports long-term health.
