Trees that Start with R
1. Rain Tree

Also known as the 5’o clock tree, the leaves of this wide-canopied tropical tree fold up before a downpour or late in the evening. Native to Central and South America, it belongs to the pea family and produces leathery pink flowers and edible pulpy fruits that taste a bit like lemons.

Red Maple is a deciduous tree adored for its color-changing foliage. This tree flourishes in high altitudes as well as swamps and lowlands in the northeastern parts of the US. As fall approaches, you’ll find its serrated leaves turn a shade of deep pink to red.
It tolerates a wide range of soil types, including different textures, moisture levels, and pH.
3. River Birch
Botanical Name: Betula nigra
Almost all parts of this tree are quite intriguing! One of the most disease-resistant birches, this deciduous tree native to Missouri can grow up to 70 feet! Sporting bright yellow foliage and golden flowers, it tolerates heavy clay soil and full sun to part shade.
While highly adaptable, this tree does love moist conditions and can be commonly spotted near river beds.
4. Redbud![Amazing Trees that Start with R](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20500%20715'%3E%3C/svg%3E)
Botanical Name: Cercis Canadensis
Next on our list of trees that start with R is another native to the eastern parts of North America—the redbud. Although smaller than the others above, its heart-shaped leaves and nectar-filled bright pink to purple flowers overshadow its compact size.
This tree attracts butterflies, bees, and songbirds and is common in woodland areas. It tolerates full sun to part shade but cannot withstand drought or too much heat. It grows well in fertile clay or sandy soil.
5. Rimu
Botanical Name: Dacrydium cupressinum
Scaling up to 150 feet or more, Rimu is a conifer native to New Zealand. It has dark red wood, which used to make furniture and finger-like spikey leaves that appear bushy. You can tell that a table is made out of Rimu if it features unique light and dark streaks.
This slow grower has a long period of adolescence with high moisture needs. But it is captivating at all its growth stages, from young, slender, and narrow to upright and imposing as an adult!
6. Rock Elm![top best Trees that Start with R](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20500%20689'%3E%3C/svg%3E)
Botanical Name: Ulmus thomasii
Rock Elm is much like a regular elm tree, only taller and skinnier. Growing up to 100 feet and living up to 300 years, this midwestern US native has an upright growth habit, with older branches featuring corky wings—hence the alternative name, cork elm!
It tolerates shade and prefers moist, well-draining sandy loam or silt soil. Rock elm can also grow in drier conditions, such as rocky ridges or limestone bluffs.
7. Ribbon Gum
Botanical Name: Eucalyptus viminalis
Native to Australia, the Ribbon Gum tree grows to massive heights of over 300 feet! Its trunk sheds long ribbons and exposes a smooth, snowy bark—hence the name. Also known as manna gum, the bark exudes a crumbly substance with a pleasant and sweet taste, made up of unfermentable sugars.
Ribbon Gum is commonly used for timber, building, and joinery. It prefers moist, wet soil and tolerate drought to an extent, but cannot stand shade.
8. Rowan![lovely Trees Beginning with R](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20500%20750'%3E%3C/svg%3E)

The heartwood of this tropical tree is sweet and fragrant, often used in making musical instruments such as sitars and guitars, yachts, boats, veneers, etc.
Rosewood trunks yield wood with a lustrous finish and are exceptionally durable. However, it is a slow-growing tree protected by sustainable forestry programs to balance harvesting and conservation.

Royal Poinciana is a striking tree that exudes royalty through its broad, umbrella-like canopy and red-orange flowers. Native to Madagascar, it thrives in tropical climates and is often called the “flame tree” because of its fiery blossoms.

12. Rubber Fig
Botanical Name: Ficus elastica
The Rubber Fig is a large tree in the banyan family of figs that can grow up to 130 feet but it’s also grown as a houseplant. It features a broad, stout trunk and glossy oval leaves. Its strong aerial roots have even been used to form living bridges in Indian states like Meghalaya, which you’ll find to this day.
All parts of the plant comprise a milky latex used earlier to make rubber. However, it isn’t the same as the Para rubber tree, which contains the official latex used in making commercial rubber.
13. Rum Cherry Tree
Botanical Name: Prunus serotina
Another member of the rose family that starts with the alphabet R is the Rum Cherry Tree. This rapid-growing forest tree’s foliage turns yellow and red during fall, and its cluster of tiny white blooms give birth to reddish black berries.
While used in wine, jelly, and for flavoring rum, studies suggest consuming large amounts of these berries could lead to cyanide poisoning!
14. Rata
Botanical Name: Metrosideros umbellata
We have so many trees from New Zealand that begin with the letter R! The Rata tree has a thick, twisting trunk that often exceeds a meter in diameter. It features glossy, dark green leaves and bright red flowers that grow during winters in the region.
This tree can live over 1000 years, but sighting its blossoms is rare, as it occurs only once every few years.
15. Riberry
Botanical Name: Syzygium luehmannii
Riberry is a small to medium tree with flaky, reddish bark, glossy green leaves, and bright pink to red berries. It is native to the low-lying rainforests of Australia and is often planted in gardens as a hedge or topiary.

River Red Gum is a tall tree that can grow up to 150 feet. It features smooth, mottled bark and long, narrow leaves and is commonly spotted along the riverbanks and floodplains of Australia. This one’s another old soul as it can live up to 1000 years.
17. Rusty Fig
Botanical Name: Ficus rubiginosa
Looking like a giant green cloud emerging from a single trunk, the Rusty Fig is one of the hardiest rubber trees. It is known for its dense spread and smooth, oval foliage, which is green on top and brownish underside.
As it grows at a relatively slower pace, it is well suited for smaller areas. In their native region of eastern Australia, they are found in rainforests, gullies, riverbanks, and rocky hillsides.
18. Rocky Mountain Fir
Botanical Name: Abies lasiocarpa
As the name suggests, this evergreen conifer is native to the Rocky Mountain range of North America. It usually grows up to about 66 feet but can sometimes scale up to even 160 feet! This tree looks down upon most others on this list not because of its colossal size but because it can be found at elevations up to 3700 meters from sea level in montane forests.
With sharp cone-shaped and bluish-green needle-like leaves, its timber is too fragile for woodwork or furniture.
19. Royal Palm
Botanical Name: Roystonea regia
