sudachi is a member of the Citrus family. Its botanical name is Citrus sudachi.
Slow-growing citrus, thought to be a wild hybrid between an ichang papeda and some variety of mandarin.
Fruit has a slightly skunky, papeda-meets-lime aroma, thin rind, very juicy, and extremely sour, like a mix of key lime and sour tangerine. Fruit is golf ball-sized, and forms in tight bunched clusters, green at first, ripening to a yellowish-orange color.sudachi grows as an annual and is an edible fruit. Being an annual plant, it tends to grow best over the course of a single year.
China is believed to be where sudachi originates from.
sudachi 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. Seedlings will be frost sensitive. Mature plants (due to papeda ancestry) will be able to handle brief frosts with no problem.
Dried seed has lower germination rate. With fresh seed, clip the extreme tip, very carefully not damaging the embryo to speed up germination.
