The Lemon guava has been a fun surprise for us here. We brought in a 15 gallon specimen last winter and it fruited really well and didn’t have any issues. The lemon guava is hardy to roughly 22 degrees. We are planning to plant one out and see how it does. The fruit has nice lemon guava like flavor. The plants are self-fertile, pest free and have required little care, they do like water, especially when flowering and fruiting. a beautiful indoor/outdoor plant.
