No, Japanese plums are not apricots; they are botanically distinct plants despite some common naming conventions. The plant often referred to as a Japanese plum, scientifically known as Prunus mume, is, in fact, neither a true apricot nor a true plum.
Understanding Japanese Plums and Apricots
The world of Prunus species can sometimes be confusing due to shared common names and similar appearances. While many fruits belong to the Prunus genus, their specific species classification defines whether they are truly a plum, an apricot, a cherry, or an almond.
What is a Japanese Plum (Prunus mume)?
The plant commonly known as the Japanese plum, or sometimes the Chinese plum or Japanese apricot, is botanically classified as Prunus mume. This species has distinct characteristics that set it apart from both true apricots (Prunus armeniaca) and true plums (Prunus domestica or Prunus salicina).
Prunus mume is highly valued for its beautiful, fragrant blossoms that often appear in late winter or early spring, even before the leaves emerge. It is a resilient plant that can be grown as a bonsai tree or planted in the ground as an ornamental tree, capable of reaching heights of up to 25 feet at maturity. While its fruit is edible, it is typically quite tart and is often used in preserves, liqueurs (like umeshu in Japan), or pickles (umeboshi) rather than eaten fresh.
Distinguishing Features
To clarify the differences, it's helpful to look at the botanical and practical distinctions between Prunus mume, true apricots, and true plums.
-
Botanical Classification: All three belong to the Prunus genus within the Rosaceae family, but they are different species.
- Prunus mume: The so-called Japanese Plum/Apricot.
- Prunus armeniaca: The true apricot, known for its sweet, fuzzy-skinned fruit.
- Prunus domestica / Prunus salicina: True plums, typically smooth-skinned and ranging from sweet to tart.
-
Fruit Characteristics:
- Prunus mume: Produces small, firm fruits with a distinct seam, often very tart, and used for processing. The skin can be slightly fuzzy.
- True Apricot (Prunus armeniaca): Features round, orange-yellow fruits with fuzzy skin and a sweet, juicy flesh.
- True Plum (Prunus domestica / Prunus salicina): Fruits vary greatly in size, color (red, purple, yellow), and sweetness, but they typically have smooth, thin skin and a juicy flesh.
Common Misconceptions
The interchangeable use of "plum" and "apricot" in the common names for Prunus mume often leads to confusion. For instance, in Japan, the fruit is called ume, which is then sometimes translated as "Japanese plum" or "Japanese apricot." This linguistic overlap does not reflect its botanical classification, which firmly places it as a unique species distinct from both.
Culinary and Ornamental Uses
While botanically unique, Prunus mume offers significant value:
- Ornamental Value: Its early, fragrant blossoms are highly prized, making it a popular choice for winter interest gardens and traditional Japanese and Chinese landscapes.
- Culinary Applications: The tart fruit is central to various East Asian culinary traditions:
- Umeboshi: Salt-pickled ume fruits, a staple in Japanese cuisine.
- Umeshu: A sweet alcoholic liqueur made by steeping ume fruits in alcohol and sugar.
- Jams and Preserves: The fruit's pectin content makes it excellent for making tart jams.
Botanical Classification Table
To further clarify the distinctions, here's a comparative overview:
| Feature | Japanese Plum (Prunus mume) | True Apricot (Prunus armeniaca) | True Plum (Prunus domestica) |
|---|---|---|---|
| Botanical Family | Rosaceae | Rosaceae | Rosaceae |
| Botanical Genus | Prunus | Prunus | Prunus |
| Botanical Species | P. mume | P. armeniaca | P. domestica |
| Common Names | Chinese Plum, Japanese Apricot, Ume | Apricot | Plum |
| Classification | Neither a true plum nor apricot | True Apricot | True Plum |
| Fruit Characteristics | Small, firm, often tart, slightly fuzzy skin | Round, orange-yellow, fuzzy skin, sweet | Various sizes/colors, smooth skin, sweet/tart |
| Primary Use | Ornamental, processed fruit (umeshu, umeboshi) | Fresh eating, preserves | Fresh eating, preserves |
| Mature Size | Up to 25 feet tall | Typically 20-30 feet tall | Varies, 15-30 feet tall |
In conclusion, while the common name "Japanese plum" might suggest a relation to plums or even apricots, botanically, Prunus mume stands as its own distinct species.
