エリオボトリヤ・ジャポニカ

Eriobotrya japonica – commonly known as the loquat – is a subtropical evergreen tree native to southeastern China and possibly southern Japan. It belongs to the Rosaceae family, which also includes apples, pears, and cherries. The tree is cultivated primarily for its sweet, tangy fruit as well as its ornamental value.

Botanical Characteristics

• Height & Shape: The loquat tree typically grows between 3 to 10 meters tall. It has a rounded crown with dense, glossy foliage.

• Leaves: The leaves are large (up to 30 cm long), leathery, dark green, and have a serrated edge. Their prominent veining gives them a distinctive look.

• Flowers: Eriobotrya japonica blooms in autumn or early winter. The small, white flowers are fragrant and grow in clusters.

• Fruit: The fruit matures in late winter to early spring. It’s a small, oval to pear-shaped drupe, yellow to orange when ripe, with a thin, fuzzy skin and juicy, sweet-tart flesh. The flavor is often compared to a mix of peach, citrus, and mango.

Cultivation

Loquats prefer mild climates and are sensitive to heavy frost. They are grown in many parts of the world, including the Mediterranean region, parts of the United States (especially California and Florida), and subtropical areas of Asia and Latin America. The tree is usually propagated by grafting or seed, although seed-grown trees may not bear fruit identical to the parent.

Uses

• Culinary: The fruit can be eaten fresh or used in jams, jellies, pies, and syrups. Loquat wine and liqueur are also popular in some cultures.

• Medicinal: In traditional Chinese medicine, loquat leaves (known as pi pa ye) are used to make herbal teas that are believed to help with respiratory ailments, coughs, and inflammation.

• Ornamental: Its attractive foliage and early flowering make it a popular choice for landscaping in suitable climates.

Interesting Facts

• Loquat trees often fruit at a time when few other fruits are in season, making them valuable for early spring harvests.

• The seeds of loquats are toxic if ingested in large quantities, as they contain cyanogenic compounds.
