According to Urban Dictionary:
Apple Tree Theory
1. Girls are like apples on a tree while boys are the pickers:
2. The best apples are at the top of the tree.
3. Some boys don’t want to reach for the good ones because they are afraid of falling and getting hurt. Instead, they just get the rotten apples from the ground that aren’t as good, but easy.
So the apples at the top think something is wrong with them, when in reality, they’re amazing. They just have to wait for the perfect person to come along, for he will climb all the way to the top.
The real truth about Urban Apple trees is that these are upright growing columnar fruit trees that will produce apples in your garden even if you have limited space.
Urban Columnar Apple trees from Evergreen H&G Showplace are loaded with fruiting spurs along the main leader, and branches are short and upright, producing straight, upright-growing, cylindrical apple trees. Plant Urban Columnar Apples in the ground, or transplant to larger containers coordinated with home and architecture and enjoy moving them around as desired. Tasty Red is a bright red apple with a sweet, juicy flavor. Blushing Delight produces a blush of reddish green fruit with a slightly sweeter taste. Golden Treat greenish-gold apples are tart in early fall, but get sweeter the longer they are on the tree. Tangy Green lime-green apples add a crisp, tart flavor to the series.
Columnar apple trees have been created to allow them to grow in smaller growing areas. Columnar apple trees look like bottle brushes, as they grow straight up and have a very small branch length. Mature columnar apple trees average eight to ten feet tall and only about two feet wide. They can grow and produce healthy fruit for about twenty years.
Columnar apple trees have many advantages to the home gardener over their full sized counterparts. First, they are smaller than semi-dwarf trees, and can therefore be grown in a smaller area. They can work well as potted plants, making them very portable. Columnar apple trees are also early producers, and will possibly grow fruit on their first year.
