These mandarins were first fruited in 1990. They were then propagated and tested in San Antonio, Texas, and at the TAMU Research and Extension Center in Uvalde. They are early-maturing, high-quality, cold tolerant varieties of mandarins. Thorniness is slight on young trees propagated from the original seedlings. Mature leaves are lanceolate and range in size from 12-16 cm long and 5-6 cm wide, with almost non-existent petiole wings; Seto leaves being the larger. Seto leaves are oblong and Miho leaves are elliptic in shape. Budded trees are small to medium in size with a low-growing, spreading habit. Miho has a more upright branching, while Seto branches tend to droop.
The color of Miho fruit develops in late summer and early fall; peel is smooth and thin and leathery. It is easy to peel and has high sugar levels. It is a slow growing dwarf tree. The fruit should be harvested around or just before Thanksgiving. The color of Seto fruit develops in late summer and early fall; peel is notably smoother and thinner than other satsumas. The fruit is noticeably flat and hence packs extremely well. The Seto fruit should also be harvested just before Thanksgiving. Maintain them with weekly watering and weed control.
