Citrus ichangensis × Citrus reticulata var. austera
Yuzu is a member of the Citrus family. Its botanical name is Citrus ichangensis × Citrus reticulata var. austera. It is an edible fruit that typically grows as an evergreen, which is defined as a plant that retains leaves throughout the year.
China is believed to be where Yuzu originates from.
Yuzu is normally fairly low maintenance and quite easy to grow, as long as a level of basic care is provided throughout the year. Being aware of the basic soil, sun and water preferences will result in a happier and healthier plant.

Loves light. In the US, seems to be happiest in spring and autumn (warm days, cool nights); otherwise a bit more rugged than other citrus, and can handle a bit of benign neglect well. Can be a little sluggish in extreme heat. Needs good drainage. Leaves have the wide petiole typical of other papeda-type citrus (sudachi, kaffir limes, shangjuan), and the leaves – when rubbed – have a sweet/spicy fragrance similar to a mix of lime and grapefruit. Can be very thorny, so handle with care.Remember to water Yuzu moderately. Yuzu is generally regarded as a hardy plant, so this plant will survive close to or on freezing temperatures.
Clip the extreme tip of seed, carefully so as to not damage the embryo. Fresh seed will sprout reliably, dried seed has lower germination rates.
Seedlings are frost sensitive; mature plants have a great deal of frost hardiness – yuzu is a wild hybrid (ichang papeda and mandarin) in its’ ancestry, so individual plants do have a range of hardiness or sensitivity, so be aware of your own individual microclimates.

Native to China, though most widely cultivated in Japan and Korea. Fruit is very unique: similar in appearance to a large, yellow mandarin, with a heavy, rugged rind. The rind is pitted with very prominent oil glands, and the fruit is very fragrant, with a spicy, grapefruit/lime fragrance.
The peel comes off very easily, and the fruit is very, very juicy, though also extremely seedy; the membranes are slippery with citrus oil. The flavor is a bit like a mild lemon, with a slight touch of grapefruit bitterness, and a very pungent spicy lime smell.
The flavor is complex, and a little funky (in a good way); it is used in a number of ways – sushi condiments, salad dressings, sorbets, soft drinks, cocktails; a Korean honey/yuzu marmalade has gained some renown. Due to the very complex flavor, it can be a challenge to use yuzu as an ingredient, though the flavor is also unforgettable.
