'REPUBLIC OF TEXAS' ORANGE: An heirloom Texas treasure dating back to the 1800s, this 10-15' tree is considered one of the most cold-hardy of all sweet oranges. It produces medium-sized, incredibly juicy fruit with a rich, sweet flavor. While it is a bit thorny and has some seeds, the taste and resilience make it a legendary choice for the Houston area. PROTECT FROM FREEZE (ESPECIALLY THE GRAFT).
