Trees serve a variety of purposes, from providing shade to giving oxygen, in addition to just being beautiful to look at. Trees that produce edible fruit are wonderful to have in the home garden, providing tasty, nutritious produce that will taste fresher and better than most fruits found in a supermarket.
The hardiest species of lemon tree is the Meyer lemon, a diminutive tree native to China that reaches a maximum height of only 10 feet tall. The tree produces round lemon fruits that are sweeter and juicier than most other types of lemon. Meyer lemon has waxy, purplish-white flowers that start to appear in the winter. These lovely blooms attract butterflies, before giving way to edible fruits. The tree grows best in full sunlight in USDA hardiness zones 8B to 10. Meyer lemon requires well-drained soil, and the tree should be watered frequently in late spring and early summer.
A native of Central America, the avocado tree (Persea americana) is an evergreen tree that keeps its glossy dark green leaves year round. The tree is cultivated commercially, and in the home landscape, primarily for its edible fruits, which are a rich source of nutrients. The tree can reach staggering heights of up to 60 feet. Avocado Trees should be grown in full sunlight in USDA zones 8 to 11. The plant must be grown in soils that are well drained and kept consistently moist.
Unsurprisingly, sweet orange (Citrus sinensis) is named after its sweet, edible orange fruits. The tree is on the smaller side, rarely reaching heights over 25 feet. Sweet orange trees boast glossy, rich green foliage and small fragrant white flowers, which bloom anytime from mid-winter until mid-spring. If the tree is to produce its signature sweet citrus fruits, it must be grown in full sunlight in USDA zones 9A to 11A. Though not picky about soil, sweet orange should be grown in well-drained soil, as the tree will not do well in waterlogged or overly wet conditions.
