Flowers and Fruit
In warm climates or if brought indoors for the winter months, lemon trees will flower and bear fruit periodically throughout the year. However, most lemon trees produce the most flowers and fruit during the summer. If your lemon tree grows outside year-round but is exposed to cold winters, then it may flower but fail to produce fruit, or it may produce lush foliage but fail to flower. Lemon fruits are oval, rich yellow and should be firm but not hard to the touch when ripe. The flowers are mildly fragrant and grow alone or in clusters. The petals are white on the top and flushed violet underneath.
