Citrus limon. Similar to the Lisbon lemon above, Eureka has fewer thorns. It tends to bear more fruit throughout the year on bushes that are vigorous yet easy to train and bear fewer thorns than many citrus varieties. A classic high-acid, flavorful lemon. Grown on dwarfing rootstock in 5 gal pots, trees are bushy, about 3' tall, flowering. ONE PER CUSTOMER, PLEASE.
