The most widely grown backyard fruit tree in Australia. Tough, productive, and fruits nearly year-round in warm climates. Eureka and Lisbon are the main varieties; Meyer is a lemon-orange hybrid (easier to grow but less acidic). A single grafted tree on dwarfing rootstock fits any suburban garden and produces more lemons than most families can use. Grafted trees fruit in 2-3 years.
