Grafted Meyer Lemon (Citrus Limon 'Meyer')Meyer Lemon is a hybrid citrus native to China. Mature trees grow 6 to 10 feet tall and produce small sweet lemons. These make great container plants for your patio and can be brought inside for winter as an attractive houseplant. All of our 3 gallon and larger citrus plants are grafted, so they usually produce fruit during their first year.
