OLL-4 Sweet Orange (Citrus sinensis ‘OLL-4’)
⚠ Citrus ships to Florida only ⚠
LIMITED AVAILABILITY! OLL-4 is a very special new commercial variety that was grown to be the most green resistant cultivar.
This sweet orange cultivar is similar to but better than Valencia. It is one of the series of OLL (‘Orie Lee Late’) oranges that was developed by the University of Florida and grower/researcher Orie Lee, patented in 2017. It is higher yielding, disease resistant, and with more cold and drought tolerance than standard orange varieties and can be grown in the garden or in containers.
OLL-4 trees grow to 19 feet high with a 16 to 18-foot spread. The greenish-white, highly fragrant flowers bloom in the early spring and develop into fruit that stays on the tree without dropping and keeps its quality into the summer. The oranges are juicy and very sweet with a flavor similar to Valencia’s. They are excellent for juice and also for eating fresh with 2 to 5 seeds per fruit and easily peeling skin.
OLL-4 grows best in full sun in rich, well-draining soil that is kept moist but not soggy. It is hardy in USDA zones 9 to 11 but can be grown in containers and even indoors in colder zones.
