Here is what it says about US 119 In the booklet "Hardy Citrus For The Southeast" by Tom McClendon.
US 119 is a citrumelo crossed with a sweet orange cross [(Poncirus trifoliate x Citrus paradisi)xCitrus sinensis] with large grapefruit-like leaves and orange fruit. The tree has a mixture of unifoliate, bifoliate, and trifoliate leaves, with trifoliate dominating. The fruit is very attractive, with a deep orange color and smooth peel. Inside, the fruit is very attractive with a rich orange color and few to no seeds. The taste is sweet with just a touch of trifoliate aftertaste. While US 119 has been touted as hardy to 10F. it remains to be seen if this is true. Young plants have been injured by temperatures in the low 20's.
Flavor: Sweet orange, few off-flavors, good quality.
