Typically a peach tree (Prunus persica) develops into a plant with a wide, spreading but rounded canopy of branches. If you are short on garden space, or wish to increase production yields in an orchard, upright-growing peach trees allows you to harvest more peaches on more trees in the same acreage. Not all peach trees with upright habit are grown for fruits, as some provide breathtaking spring flower displays on column-like plants. Make sure to confirm the upright peach tree variety you purchase is known to produce fruits.
Developed at the Appalachian Fruit Research Station in Kearneysville, West Virginia and carrying a U.S. plant patent, "Crimson Rocket" is described as having a column-like grown habit. The branch angles off of the main tree trunk are sharp, only 35 to 40 degrees off of vertical according to the U.S. Trademark and Plant Patent Office's records. The dessert-quality fruits are firm, yellow and have substantial red blushing. In American orchards, the fruits ripen and are ready for harvest by mid-August.
Also developed in Kearneysville and carrying a U.S. plant patent, "Sweet-N-Up" develops a slightly wider column-like grown habit. The branch angles off of the main tree trunk are upward-angled, only 40 to 50 degrees off of vertical according to the U.S. Trademark and Plant Patent Office's records. The dessert-quality fruits are firm, heavily red-blushed over yellow skin. They are ripe and harvested in late August.
The most recent introduction from the Appalachian Fruit Research Station in Kearneysville is the variety "Summerfest." As of mid-2010, a plant patent had been applied for, but was not listed in the U.S. Trademark and Plant Patent Office online database. This upright peach tree was developed as a hybrid with "Crimson Rocket" being one parent according to Adams County Nursery. "Summerfest" produces fruits that are also regarded as dessert-type and are uniformly round with an orange skin that deepens to dark red.
The ornamental flowering peach trees with distinctively upright, narrow canopies and growth habits are part of the Corinthian Series. These trees flower abundantly each early spring but fail to produce fruits. They are exclusively used for garden landscapes and include varieties that have either rose, pink, pale or white flowers. The cultivar names reveal their identity and inclusion in the Corinthian Series: "Corinthian Mauve," "Corinthian White," "Cornithina Pink" and "Corinthian Rose."
