"Pink Pearl" (Malus domestica "Pink Pearl") is a semi-dwarf apple tree that grows to a mature height of between 15 to 20 feet. It is characterized by bright pink blooms that appear in spring and give way in late summer to yellowish green apples that have pink flesh on the inside.
The "Pink Pearl" apple was introduced to the public in 1944 by Albert Etter, a California plant breeder who was known as the "Luther Burbank of Humboldt County." He gained fame initially for his work on strawberries, crossing common garden varieties with wild beach strawberries. After years of hybridizing strawberries, Etter started hybridizing apples in the 1920s. Using the same approach with apples that he did with strawberries, Etter experimented with crossing crabapples with popular modern apple varieties.
"Pink Pearl" produces apples that are medium sized and conical, with a slightly translucent, yellowish green skin that may have a reddish pink blush. The flesh of the apple is bright pink, with a crisp texture and a tart flavor. The fruit is good both raw and cooked. The unusual color of the flesh can be exploited to create striking desserts and applesauces. Fruits are ready for harvest from late August to mid-September.
"Pink Pearl" is suitable for gardens in U.S. Department of Agriculture plant hardiness zones 6 to 9, where it must grow in full sunlight to flower and produce fruit. Do not plant "Pink Pearl" near large trees or buildings, which will interfere with the tree's sunlight. Avoid planting near grass, as grass competes with the tree for water and other nutrients. If planting in a lawn, give the tree at least 4 feet of grass-free space. Animals may damage "Pink Pearl" if grown near wildlife inhabited areas.
Apple trees are not terribly picky about soil, so long as soil is well draining and moist. Do not plant "Pink Pearl" in an area where water floods regularly, as apples do not like to have "wet feet." To help prevent pests, prune away any old or diseased branches, and remove old or shriveled apples. Clear away any collected debris from under the plant, as pests can overwinter in fallen leaves. Horticultural oil can be beneficial to prevent scale.
