Fruit trees typically flower before they produce fruit, therefore summer-blooming fruit tree types include the ones that produce fruit in late summer or fall. Occasionally, a fruit tree which normally blooms throughout spring, such as an apple tree, flowers during summer because of abnormal weather patterns. Many booming fruit trees add attractive colour to the garden, like starfruit trees with purple or pink blooms.
American elder (Sambucus canadensis) is a deciduous tree or shrub that grows white blooms between June and August. It tolerates U.S. Department of Agriculture plant hardiness zones 4 through 9, though it can occasionally grow in the warmest areas of USDA zone 3. The tree grows throughout the majority of the United States and much of Canada. It produces edible fruit in September. This tree prefers full sunlight, well-drained soils along with a slightly acidic soil pH.
Lime trees (Citrus aurantifolia) produce white flowers during summer followed by limes during autumn. Citrus trees generally do best in USDA zones 9 and warmer, and many types of limes grow best in USDA zones 9 and 10. For instance, Mexican limes succeed in warm coastal areas which never freeze, while hybrid limequats can tolerate occasional frosts. Citrus trees favor well-drained soils and perform best when gardeners plant them during spring until the weather becomes hot.
Starfruit (Averrhoa carambola), indigenous to Southeast Asia, is cultivated in tropical and subtropical parts of the United States, like Florida and areas of California that rarely freeze. Temperatures as cold as 20 degrees Fahrenheit may ruin starfruit trees. They grow best in USDA zones 9b through 11. Starfruit trees produce pink to lavender blooms during summer, followed by sweet, juicy fruit during autumn and winter. They grow best in well-drained soils using a slightly acidic pH. In addition they favor protection from the wind.
Meiwa kumquat (Fortunella crassifolia) is a sort of Asian kumquat that’s cultivated in warmer parts of the United States, like Florida and California. It grows white blooms during summer and produces edible citrus fruits during winter. Kumquat trees grow slowly and stay relatively small. They tolerate temperatures as cold as 14 degrees Fahrenheit, and they grow best in USDA zones 8b through 10. All these trees are hardier than a number of different types of citrus and can grow in Mediterranean climates.
